Throughout this breakout session the following controller releases are used
bull AirOS 76130 release is mainly used because of
ndash Pre-Auth DNS-based ACL enhancement
ndash iOS7 Captive Network Assistant (CNA) behavior change
ndash Stability improvements
bull AirOS 74130
ndash Alternative AirOS release containing most ISE ndash MDM Integration related features and stability improvements
ndash Missing Pre-Auth DNS-based ACL enhancementTherefore the first proposed implementation option later in this deck ldquoPre-Auth DNS-based ACLrdquo isnrsquot applicable
bull A note to converged access controllers
ndash IOS-XE 33 adds URL-redirection functionality
ndash IOS-XE 36 adds FQDN ACLs

WLC ndash URL Redirection ACL
bull Problem Statement To register iOS and Android devices for BYOD or MDM they may require Internet access for either downloading supplicant software or for device validation from highly dynamic sources like iTunes and Google Play Same applies for MDM marked non-compliant devices In contrast WLC URL redirection ACL only offers static IP-based rule definition
bull Workaround (works also with older WLC versions eg 741300)
a) Permit full Internet access denyredirect only internal IP address ranges
b) Permit access to Apple and Google IP ranges denyredirect other traffic
c) Fake DNS resolutionbull Optional Plus external DNS-based network access enforcement (ASA WSA or others)
d) Out-of-band MDM onboarding just do endpoint compliance checking

ndash MDM cachingbull If device connects to network ISE caches the MDM state
bull Next time device attempts to log-on ISE use the cache to allow access per previous MDM check
bull Once the device is on the network ISE checks with MDM using API call if the MDM state has changed (eg compliant -gt non-compliant)
bull If the state has changed ISE issues a COA to give a new policy (as per updated MDM attributes)
bull A note to ISE 13 12 patches

copy 2015 Cisco andor its affiliates All rights reservedBRKSEC-2035 Cisco Public
bull Problem Statement Any change to interface IP addressing (network relocation vMotion network infrastructure changes etc) requires new certificates to be generated with SAN attributes updated for new IP addresses
ndash Time-consuming process
ndash New certificates signed by 3rd-party CAs can be expensive
ndash Disruption to application services after new cert loaded
bull Solution
ndash Interface Alias Optionally assign ISE node interface (eth1 eth2 eth3) a unique hostnameFQDN which can be resolved to its local IP address using DNS
ndash Each PSN tracks which interfaces are enabled for each service and dynamically substitutes IP variable for URL redirection to the PSNs local interface alias (hostname + domain)
bull Considerations
ndash Manual configuration process from CLI
ndash Requires DNS to be updates for each alias

FQDN in SAN
60
bull Problem Statement Every ISE node requires a unique certificate
ndash New certificates signed by 3rd-party CAs can be expensive
ndash Time-consuming process to generate new certs each time new node added
ndash Certificate SAN must include FQDN entry for other web services (Sponsor MDP etc)
ndash Some endpoints require each PSN cert to be trusted and will prompt user to accept
bull Solution Wildcard Certificates
ndash Allows multiple ISE nodes to share single certificate for WebEAP authentication
ndash No longer requires custom SAN with node FQDN or interface IP addresses
ndash Most seamless and improved end-user experience
bull Considerations
ndash Less secure than unique certificate per node greater care to safeguard private key
ndash Limit exposure and deploy ISE into subdomain eg isecompanycom

Key business driver for multi-interface support is traffic separation and assumption that traffic for one service that enters on interface X will return from the interfacenetwork path
bull Problem Statement
ndash Packets received on any ISE interface relies on CARS routing table to determine egress interface and next hop address
bull Solution
ndash Static routes for each endpoint subnet must be configured on each node using CLI to use the desired web service interface
ndash Source NAT to Web Portal interfaces and configure static route to NATrsquoed network
bull Considerations
ndash If NAT not used then depending on network size and addressing complexity may require hundreds of static routes to be configured very difficult to manage and maintain
ndash Dedicated interface for Anchor Controller use case should not be impacted since client IP is local (L2 adjacent) to dedicated ISE interface in DMZ

Connection Messages Explanation
Connection Failed
Please check the connection
parameters
A routing or firewall problem exists between the ISE located in the data center and the MDM located in either the
DMZ or Cloud The firewalls configuration should be checked to confirm HTTPS is allowed in this direction
Connection Failed
404 Not Found
The most likely cause of an HTML 404 error code is that an instance was configured when it was not required or
that the wrong instance has been configured
Connection Failed
403 Forbidden
The user account setup on the MDM server does not have the proper roles associated to it Validate that the
account being used by ISE is assigned the REST API MDM role
Connection Failed
401 UnauthorizedThe user name or password is not correct for the account being used by ISE
Connection Failed There is a
problem with the server
certificate or ISE Trust store
ISE does not trust the certificate presented by the MDM website This indicates the certificate was not imported to
the ISE certificate store or the certificate has expired since it was imported
The MDM Server details are
valid and the connectivity was
successful
The connection has successfully been tested The administrator should also verify the MDM AUTHZ dictionary
has been populated with attributes

bull Scalability = 30 API calls per second ( gt100`000 callsh)Consider Internet bandwidth and latency for cloud-based solutions
Passive Reassessment
bull Bulk recheck against MDM server using configurable timer (polling interval)
bull If result of periodic recheck shows that a connected endpoint is no longer compliant ISE sends a CoA to terminate session
Survivability
bull CoA is NOT sent for devices granted access while MDM server unavailable
bull If device is granted a ldquofail openrdquo or other limited access state (for example URL-redirected to MDM) user can hit Continue button when MDM is back online to trigger CoA

bull Problem Statement To register iOS and Android devices for BYOD or MDM they may require Internet access for either downloading supplicant software or for device validation from highly dynamic sources like iTunes and Google Play Same applies for MDM marked non-compliant devices In contrast WLC URL redirection ACL only offers static IP-based rule definition
bull Workaround (works also with older WLC versions eg 741300)
a) Permit full Internet access denyredirect only internal IP address ranges
b) Permit access to Apple and Google IP ranges denyredirect other traffic
c) Fake DNS resolutionbull Optional Plus external DNS-based network access enforcement (ASA WSA or others)

copy 2015 Cisco andor its affiliates All rights reservedBRKSEC-2035 Cisco Public
bull Problem Statement Any change to interface IP addressing (network relocation vMotion network infrastructure changes etc) requires new certificates to be generated with SAN attributes updated for new IP addresses
ndash Time-consuming process
ndash New certificates signed by 3rd-party CAs can be expensive
ndash Disruption to application services after new cert loaded
bull Solution
ndash Interface Alias Optionally assign ISE node interface (eth1 eth2 eth3) a unique hostnameFQDN which can be resolved to its local IP address using DNS
ndash Each PSN tracks which interfaces are enabled for each service and dynamically substitutes IP variable for URL redirection to the PSNs local interface alias (hostname + domain)
bull Considerations
ndash Manual configuration process from CLI
ndash Requires DNS to be updates for each alias

FQDN in SAN
60
bull Problem Statement Every ISE node requires a unique certificate
ndash New certificates signed by 3rd-party CAs can be expensive
ndash Time-consuming process to generate new certs each time new node added
ndash Certificate SAN must include FQDN entry for other web services (Sponsor MDP etc)
ndash Some endpoints require each PSN cert to be trusted and will prompt user to accept
bull Solution Wildcard Certificates
ndash Allows multiple ISE nodes to share single certificate for WebEAP authentication
ndash No longer requires custom SAN with node FQDN or interface IP addresses
ndash Most seamless and improved end-user experience
bull Considerations
ndash Less secure than unique certificate per node greater care to safeguard private key
ndash Limit exposure and deploy ISE into subdomain eg isecompanycom

Key business driver for multi-interface support is traffic separation and assumption that traffic for one service that enters on interface X will return from the interfacenetwork path
bull Problem Statement
ndash Packets received on any ISE interface relies on CARS routing table to determine egress interface and next hop address
bull Solution
ndash Static routes for each endpoint subnet must be configured on each node using CLI to use the desired web service interface
ndash Source NAT to Web Portal interfaces and configure static route to NATrsquoed network
bull Considerations
ndash If NAT not used then depending on network size and addressing complexity may require hundreds of static routes to be configured very difficult to manage and maintain
ndash Dedicated interface for Anchor Controller use case should not be impacted since client IP is local (L2 adjacent) to dedicated ISE interface in DMZ

Connection Messages Explanation
Connection Failed
Please check the connection
parameters
A routing or firewall problem exists between the ISE located in the data center and the MDM located in either the
DMZ or Cloud The firewalls configuration should be checked to confirm HTTPS is allowed in this direction
Connection Failed
404 Not Found
The most likely cause of an HTML 404 error code is that an instance was configured when it was not required or
that the wrong instance has been configured
Connection Failed
403 Forbidden
The user account setup on the MDM server does not have the proper roles associated to it Validate that the
account being used by ISE is assigned the REST API MDM role
Connection Failed
401 UnauthorizedThe user name or password is not correct for the account being used by ISE
Connection Failed There is a
problem with the server
certificate or ISE Trust store
ISE does not trust the certificate presented by the MDM website This indicates the certificate was not imported to
the ISE certificate store or the certificate has expired since it was imported
The MDM Server details are
valid and the connectivity was
successful
The connection has successfully been tested The administrator should also verify the MDM AUTHZ dictionary
has been populated with attributes

ndash iOS7 Captive Network Assistant (CNA) behavior change
ndash Stability improvements
bull AirOS 74130
ndash Alternative AirOS release containing most ISE ndash MDM Integration related features and stability improvements
ndash Missing Pre-Auth DNS-based ACL enhancementTherefore the first proposed implementation option later in this deck ldquoPre-Auth DNS-based ACLrdquo isnrsquot applicable

bull Problem Statement To register iOS and Android devices for BYOD or MDM they may require Internet access for either downloading supplicant software or for device validation from highly dynamic sources like iTunes and Google Play Same applies for MDM marked non-compliant devices In contrast WLC URL redirection ACL only offers static IP-based rule definition
bull Workaround (works also with older WLC versions eg 741300)
a) Permit full Internet access denyredirect only internal IP address ranges
b) Permit access to Apple and Google IP ranges denyredirect other traffic
c) Fake DNS resolutionbull Optional Plus external DNS-based network access enforcement (ASA WSA or others)

copy 2015 Cisco andor its affiliates All rights reservedBRKSEC-2035 Cisco Public
bull Problem Statement Any change to interface IP addressing (network relocation vMotion network infrastructure changes etc) requires new certificates to be generated with SAN attributes updated for new IP addresses
ndash Time-consuming process
ndash New certificates signed by 3rd-party CAs can be expensive
ndash Disruption to application services after new cert loaded
bull Solution
ndash Interface Alias Optionally assign ISE node interface (eth1 eth2 eth3) a unique hostnameFQDN which can be resolved to its local IP address using DNS
ndash Each PSN tracks which interfaces are enabled for each service and dynamically substitutes IP variable for URL redirection to the PSNs local interface alias (hostname + domain)
bull Considerations
ndash Manual configuration process from CLI
ndash Requires DNS to be updates for each alias

FQDN in SAN
60
bull Problem Statement Every ISE node requires a unique certificate
ndash New certificates signed by 3rd-party CAs can be expensive
ndash Time-consuming process to generate new certs each time new node added
ndash Certificate SAN must include FQDN entry for other web services (Sponsor MDP etc)
ndash Some endpoints require each PSN cert to be trusted and will prompt user to accept
bull Solution Wildcard Certificates
ndash Allows multiple ISE nodes to share single certificate for WebEAP authentication
ndash No longer requires custom SAN with node FQDN or interface IP addresses
ndash Most seamless and improved end-user experience
bull Considerations
ndash Less secure than unique certificate per node greater care to safeguard private key
ndash Limit exposure and deploy ISE into subdomain eg isecompanycom

Key business driver for multi-interface support is traffic separation and assumption that traffic for one service that enters on interface X will return from the interfacenetwork path
bull Problem Statement
ndash Packets received on any ISE interface relies on CARS routing table to determine egress interface and next hop address
bull Solution
ndash Static routes for each endpoint subnet must be configured on each node using CLI to use the desired web service interface
ndash Source NAT to Web Portal interfaces and configure static route to NATrsquoed network
bull Considerations
ndash If NAT not used then depending on network size and addressing complexity may require hundreds of static routes to be configured very difficult to manage and maintain
ndash Dedicated interface for Anchor Controller use case should not be impacted since client IP is local (L2 adjacent) to dedicated ISE interface in DMZ

Connection Messages Explanation
Connection Failed
Please check the connection
parameters
A routing or firewall problem exists between the ISE located in the data center and the MDM located in either the
DMZ or Cloud The firewalls configuration should be checked to confirm HTTPS is allowed in this direction
Connection Failed
404 Not Found
The most likely cause of an HTML 404 error code is that an instance was configured when it was not required or
that the wrong instance has been configured
Connection Failed
403 Forbidden
The user account setup on the MDM server does not have the proper roles associated to it Validate that the
account being used by ISE is assigned the REST API MDM role
Connection Failed
401 UnauthorizedThe user name or password is not correct for the account being used by ISE
Connection Failed There is a
problem with the server
certificate or ISE Trust store
ISE does not trust the certificate presented by the MDM website This indicates the certificate was not imported to
the ISE certificate store or the certificate has expired since it was imported
The MDM Server details are
valid and the connectivity was
successful
The connection has successfully been tested The administrator should also verify the MDM AUTHZ dictionary
has been populated with attributes

bull Scalability = 30 API calls per second ( gt100`000 callsh)Consider Internet bandwidth and latency for cloud-based solutions
Passive Reassessment
bull Bulk recheck against MDM server using configurable timer (polling interval)
bull If result of periodic recheck shows that a connected endpoint is no longer compliant ISE sends a CoA to terminate session
Survivability
bull CoA is NOT sent for devices granted access while MDM server unavailable
bull If device is granted a ldquofail openrdquo or other limited access state (for example URL-redirected to MDM) user can hit Continue button when MDM is back online to trigger CoA

bull Problem Statement To register iOS and Android devices for BYOD or MDM they may require Internet access for either downloading supplicant software or for device validation from highly dynamic sources like iTunes and Google Play Same applies for MDM marked non-compliant devices In contrast WLC URL redirection ACL only offers static IP-based rule definition
bull Workaround (works also with older WLC versions eg 741300)
a) Permit full Internet access denyredirect only internal IP address ranges
b) Permit access to Apple and Google IP ranges denyredirect other traffic
c) Fake DNS resolutionbull Optional Plus external DNS-based network access enforcement (ASA WSA or others)

copy 2015 Cisco andor its affiliates All rights reservedBRKSEC-2035 Cisco Public
bull Problem Statement Any change to interface IP addressing (network relocation vMotion network infrastructure changes etc) requires new certificates to be generated with SAN attributes updated for new IP addresses
ndash Time-consuming process
ndash New certificates signed by 3rd-party CAs can be expensive
ndash Disruption to application services after new cert loaded
bull Solution
ndash Interface Alias Optionally assign ISE node interface (eth1 eth2 eth3) a unique hostnameFQDN which can be resolved to its local IP address using DNS
ndash Each PSN tracks which interfaces are enabled for each service and dynamically substitutes IP variable for URL redirection to the PSNs local interface alias (hostname + domain)
bull Considerations
ndash Manual configuration process from CLI
ndash Requires DNS to be updates for each alias

FQDN in SAN
60
bull Problem Statement Every ISE node requires a unique certificate
ndash New certificates signed by 3rd-party CAs can be expensive
ndash Time-consuming process to generate new certs each time new node added
ndash Certificate SAN must include FQDN entry for other web services (Sponsor MDP etc)
ndash Some endpoints require each PSN cert to be trusted and will prompt user to accept
bull Solution Wildcard Certificates
ndash Allows multiple ISE nodes to share single certificate for WebEAP authentication
ndash No longer requires custom SAN with node FQDN or interface IP addresses
ndash Most seamless and improved end-user experience
bull Considerations
ndash Less secure than unique certificate per node greater care to safeguard private key
ndash Limit exposure and deploy ISE into subdomain eg isecompanycom

Key business driver for multi-interface support is traffic separation and assumption that traffic for one service that enters on interface X will return from the interfacenetwork path
bull Problem Statement
ndash Packets received on any ISE interface relies on CARS routing table to determine egress interface and next hop address
bull Solution
ndash Static routes for each endpoint subnet must be configured on each node using CLI to use the desired web service interface
ndash Source NAT to Web Portal interfaces and configure static route to NATrsquoed network
bull Considerations
ndash If NAT not used then depending on network size and addressing complexity may require hundreds of static routes to be configured very difficult to manage and maintain
ndash Dedicated interface for Anchor Controller use case should not be impacted since client IP is local (L2 adjacent) to dedicated ISE interface in DMZ

Connection Messages Explanation
Connection Failed
Please check the connection
parameters
A routing or firewall problem exists between the ISE located in the data center and the MDM located in either the
DMZ or Cloud The firewalls configuration should be checked to confirm HTTPS is allowed in this direction
Connection Failed
404 Not Found
The most likely cause of an HTML 404 error code is that an instance was configured when it was not required or
that the wrong instance has been configured
Connection Failed
403 Forbidden
The user account setup on the MDM server does not have the proper roles associated to it Validate that the
account being used by ISE is assigned the REST API MDM role
Connection Failed
401 UnauthorizedThe user name or password is not correct for the account being used by ISE
Connection Failed There is a
problem with the server
certificate or ISE Trust store
ISE does not trust the certificate presented by the MDM website This indicates the certificate was not imported to
the ISE certificate store or the certificate has expired since it was imported
The MDM Server details are
valid and the connectivity was
successful
The connection has successfully been tested The administrator should also verify the MDM AUTHZ dictionary
has been populated with attributes

ndash iOS7 Captive Network Assistant (CNA) behavior change
ndash Stability improvements
bull AirOS 74130
ndash Alternative AirOS release containing most ISE ndash MDM Integration related features and stability improvements
ndash Missing Pre-Auth DNS-based ACL enhancementTherefore the first proposed implementation option later in this deck ldquoPre-Auth DNS-based ACLrdquo isnrsquot applicable

bull Problem Statement To register iOS and Android devices for BYOD or MDM they may require Internet access for either downloading supplicant software or for device validation from highly dynamic sources like iTunes and Google Play Same applies for MDM marked non-compliant devices In contrast WLC URL redirection ACL only offers static IP-based rule definition
bull Workaround (works also with older WLC versions eg 741300)
a) Permit full Internet access denyredirect only internal IP address ranges
b) Permit access to Apple and Google IP ranges denyredirect other traffic
c) Fake DNS resolutionbull Optional Plus external DNS-based network access enforcement (ASA WSA or others)
d) Out-of-band MDM onboarding just do endpoint compliance checking

attribute entry for each interface IP address used for URL-

copy 2015 Cisco andor its affiliates All rights reservedBRKSEC-2035 Cisco Public
bull Problem Statement Any change to interface IP addressing (network relocation vMotion network infrastructure changes etc) requires new certificates to be generated with SAN attributes updated for new IP addresses
ndash Time-consuming process
ndash New certificates signed by 3rd-party CAs can be expensive
ndash Disruption to application services after new cert loaded
bull Solution
ndash Interface Alias Optionally assign ISE node interface (eth1 eth2 eth3) a unique hostnameFQDN which can be resolved to its local IP address using DNS
ndash Each PSN tracks which interfaces are enabled for each service and dynamically substitutes IP variable for URL redirection to the PSNs local interface alias (hostname + domain)
bull Considerations
ndash Manual configuration process from CLI
ndash Requires DNS to be updates for each alias

FQDN in SAN
60
bull Problem Statement Every ISE node requires a unique certificate
ndash New certificates signed by 3rd-party CAs can be expensive
ndash Time-consuming process to generate new certs each time new node added
ndash Certificate SAN must include FQDN entry for other web services (Sponsor MDP etc)
ndash Some endpoints require each PSN cert to be trusted and will prompt user to accept
bull Solution Wildcard Certificates
ndash Allows multiple ISE nodes to share single certificate for WebEAP authentication
ndash No longer requires custom SAN with node FQDN or interface IP addresses
ndash Most seamless and improved end-user experience
bull Considerations
ndash Less secure than unique certificate per node greater care to safeguard private key
ndash Limit exposure and deploy ISE into subdomain eg isecompanycom

Key business driver for multi-interface support is traffic separation and assumption that traffic for one service that enters on interface X will return from the interfacenetwork path
bull Problem Statement
ndash Packets received on any ISE interface relies on CARS routing table to determine egress interface and next hop address
bull Solution
ndash Static routes for each endpoint subnet must be configured on each node using CLI to use the desired web service interface
ndash Source NAT to Web Portal interfaces and configure static route to NATrsquoed network
bull Considerations
ndash If NAT not used then depending on network size and addressing complexity may require hundreds of static routes to be configured very difficult to manage and maintain
ndash Dedicated interface for Anchor Controller use case should not be impacted since client IP is local (L2 adjacent) to dedicated ISE interface in DMZ

Connection Messages Explanation
Connection Failed
Please check the connection
parameters
A routing or firewall problem exists between the ISE located in the data center and the MDM located in either the
DMZ or Cloud The firewalls configuration should be checked to confirm HTTPS is allowed in this direction
Connection Failed
404 Not Found
The most likely cause of an HTML 404 error code is that an instance was configured when it was not required or
that the wrong instance has been configured
Connection Failed
403 Forbidden
The user account setup on the MDM server does not have the proper roles associated to it Validate that the
account being used by ISE is assigned the REST API MDM role
Connection Failed
401 UnauthorizedThe user name or password is not correct for the account being used by ISE
Connection Failed There is a
problem with the server
certificate or ISE Trust store
ISE does not trust the certificate presented by the MDM website This indicates the certificate was not imported to
the ISE certificate store or the certificate has expired since it was imported
The MDM Server details are
valid and the connectivity was
successful
The connection has successfully been tested The administrator should also verify the MDM AUTHZ dictionary
has been populated with attributes

bull Scalability = 30 API calls per second ( gt100`000 callsh)Consider Internet bandwidth and latency for cloud-based solutions
Passive Reassessment
bull Bulk recheck against MDM server using configurable timer (polling interval)
bull If result of periodic recheck shows that a connected endpoint is no longer compliant ISE sends a CoA to terminate session
Survivability
bull CoA is NOT sent for devices granted access while MDM server unavailable
bull If device is granted a ldquofail openrdquo or other limited access state (for example URL-redirected to MDM) user can hit Continue button when MDM is back online to trigger CoA

bull Problem Statement To register iOS and Android devices for BYOD or MDM they may require Internet access for either downloading supplicant software or for device validation from highly dynamic sources like iTunes and Google Play Same applies for MDM marked non-compliant devices In contrast WLC URL redirection ACL only offers static IP-based rule definition
bull Workaround (works also with older WLC versions eg 741300)
a) Permit full Internet access denyredirect only internal IP address ranges
b) Permit access to Apple and Google IP ranges denyredirect other traffic
c) Fake DNS resolutionbull Optional Plus external DNS-based network access enforcement (ASA WSA or others)

copy 2015 Cisco andor its affiliates All rights reservedBRKSEC-2035 Cisco Public
bull Problem Statement Any change to interface IP addressing (network relocation vMotion network infrastructure changes etc) requires new certificates to be generated with SAN attributes updated for new IP addresses
ndash Time-consuming process
ndash New certificates signed by 3rd-party CAs can be expensive
ndash Disruption to application services after new cert loaded
bull Solution
ndash Interface Alias Optionally assign ISE node interface (eth1 eth2 eth3) a unique hostnameFQDN which can be resolved to its local IP address using DNS
ndash Each PSN tracks which interfaces are enabled for each service and dynamically substitutes IP variable for URL redirection to the PSNs local interface alias (hostname + domain)
bull Considerations
ndash Manual configuration process from CLI
ndash Requires DNS to be updates for each alias

FQDN in SAN
60
bull Problem Statement Every ISE node requires a unique certificate
ndash New certificates signed by 3rd-party CAs can be expensive
ndash Time-consuming process to generate new certs each time new node added
ndash Certificate SAN must include FQDN entry for other web services (Sponsor MDP etc)
ndash Some endpoints require each PSN cert to be trusted and will prompt user to accept
bull Solution Wildcard Certificates
ndash Allows multiple ISE nodes to share single certificate for WebEAP authentication
ndash No longer requires custom SAN with node FQDN or interface IP addresses
ndash Most seamless and improved end-user experience
bull Considerations
ndash Less secure than unique certificate per node greater care to safeguard private key
ndash Limit exposure and deploy ISE into subdomain eg isecompanycom

Key business driver for multi-interface support is traffic separation and assumption that traffic for one service that enters on interface X will return from the interfacenetwork path
bull Problem Statement
ndash Packets received on any ISE interface relies on CARS routing table to determine egress interface and next hop address
bull Solution
ndash Static routes for each endpoint subnet must be configured on each node using CLI to use the desired web service interface
ndash Source NAT to Web Portal interfaces and configure static route to NATrsquoed network
bull Considerations
ndash If NAT not used then depending on network size and addressing complexity may require hundreds of static routes to be configured very difficult to manage and maintain
ndash Dedicated interface for Anchor Controller use case should not be impacted since client IP is local (L2 adjacent) to dedicated ISE interface in DMZ

Connection Messages Explanation
Connection Failed
Please check the connection
parameters
A routing or firewall problem exists between the ISE located in the data center and the MDM located in either the
DMZ or Cloud The firewalls configuration should be checked to confirm HTTPS is allowed in this direction
Connection Failed
404 Not Found
The most likely cause of an HTML 404 error code is that an instance was configured when it was not required or
that the wrong instance has been configured
Connection Failed
403 Forbidden
The user account setup on the MDM server does not have the proper roles associated to it Validate that the
account being used by ISE is assigned the REST API MDM role
Connection Failed
401 UnauthorizedThe user name or password is not correct for the account being used by ISE
Connection Failed There is a
problem with the server
certificate or ISE Trust store
ISE does not trust the certificate presented by the MDM website This indicates the certificate was not imported to
the ISE certificate store or the certificate has expired since it was imported
The MDM Server details are
valid and the connectivity was
successful
The connection has successfully been tested The administrator should also verify the MDM AUTHZ dictionary
has been populated with attributes

Passive Reassessment
bull Bulk recheck against MDM server using configurable timer (polling interval)
bull If result of periodic recheck shows that a connected endpoint is no longer compliant ISE sends a CoA to terminate session
Survivability
bull CoA is NOT sent for devices granted access while MDM server unavailable

ndash iOS7 Captive Network Assistant (CNA) behavior change
ndash Stability improvements
bull AirOS 74130
ndash Alternative AirOS release containing most ISE ndash MDM Integration related features and stability improvements
ndash Missing Pre-Auth DNS-based ACL enhancementTherefore the first proposed implementation option later in this deck ldquoPre-Auth DNS-based ACLrdquo isnrsquot applicable

bull Problem Statement To register iOS and Android devices for BYOD or MDM they may require Internet access for either downloading supplicant software or for device validation from highly dynamic sources like iTunes and Google Play Same applies for MDM marked non-compliant devices In contrast WLC URL redirection ACL only offers static IP-based rule definition
bull Workaround (works also with older WLC versions eg 741300)
a) Permit full Internet access denyredirect only internal IP address ranges
b) Permit access to Apple and Google IP ranges denyredirect other traffic
c) Fake DNS resolutionbull Optional Plus external DNS-based network access enforcement (ASA WSA or others)
d) Out-of-band MDM onboarding just do endpoint compliance checking

attribute entry for each interface IP address used for URL-

copy 2015 Cisco andor its affiliates All rights reservedBRKSEC-2035 Cisco Public
bull Problem Statement Any change to interface IP addressing (network relocation vMotion network infrastructure changes etc) requires new certificates to be generated with SAN attributes updated for new IP addresses
ndash Time-consuming process
ndash New certificates signed by 3rd-party CAs can be expensive
ndash Disruption to application services after new cert loaded
bull Solution
ndash Interface Alias Optionally assign ISE node interface (eth1 eth2 eth3) a unique hostnameFQDN which can be resolved to its local IP address using DNS
ndash Each PSN tracks which interfaces are enabled for each service and dynamically substitutes IP variable for URL redirection to the PSNs local interface alias (hostname + domain)
bull Considerations
ndash Manual configuration process from CLI
ndash Requires DNS to be updates for each alias

FQDN in SAN
60
bull Problem Statement Every ISE node requires a unique certificate
ndash New certificates signed by 3rd-party CAs can be expensive
ndash Time-consuming process to generate new certs each time new node added
ndash Certificate SAN must include FQDN entry for other web services (Sponsor MDP etc)
ndash Some endpoints require each PSN cert to be trusted and will prompt user to accept
bull Solution Wildcard Certificates
ndash Allows multiple ISE nodes to share single certificate for WebEAP authentication
ndash No longer requires custom SAN with node FQDN or interface IP addresses
ndash Most seamless and improved end-user experience
bull Considerations
ndash Less secure than unique certificate per node greater care to safeguard private key
ndash Limit exposure and deploy ISE into subdomain eg isecompanycom

Key business driver for multi-interface support is traffic separation and assumption that traffic for one service that enters on interface X will return from the interfacenetwork path
bull Problem Statement
ndash Packets received on any ISE interface relies on CARS routing table to determine egress interface and next hop address
bull Solution
ndash Static routes for each endpoint subnet must be configured on each node using CLI to use the desired web service interface
ndash Source NAT to Web Portal interfaces and configure static route to NATrsquoed network
bull Considerations
ndash If NAT not used then depending on network size and addressing complexity may require hundreds of static routes to be configured very difficult to manage and maintain
ndash Dedicated interface for Anchor Controller use case should not be impacted since client IP is local (L2 adjacent) to dedicated ISE interface in DMZ

Connection Messages Explanation
Connection Failed
Please check the connection
parameters
A routing or firewall problem exists between the ISE located in the data center and the MDM located in either the
DMZ or Cloud The firewalls configuration should be checked to confirm HTTPS is allowed in this direction
Connection Failed
404 Not Found
The most likely cause of an HTML 404 error code is that an instance was configured when it was not required or
that the wrong instance has been configured
Connection Failed
403 Forbidden
The user account setup on the MDM server does not have the proper roles associated to it Validate that the
account being used by ISE is assigned the REST API MDM role
Connection Failed
401 UnauthorizedThe user name or password is not correct for the account being used by ISE
Connection Failed There is a
problem with the server
certificate or ISE Trust store
ISE does not trust the certificate presented by the MDM website This indicates the certificate was not imported to
the ISE certificate store or the certificate has expired since it was imported
The MDM Server details are
valid and the connectivity was
successful
The connection has successfully been tested The administrator should also verify the MDM AUTHZ dictionary
has been populated with attributes

bull Scalability = 30 API calls per second ( gt100`000 callsh)Consider Internet bandwidth and latency for cloud-based solutions
Passive Reassessment
bull Bulk recheck against MDM server using configurable timer (polling interval)
bull If result of periodic recheck shows that a connected endpoint is no longer compliant ISE sends a CoA to terminate session
Survivability
bull CoA is NOT sent for devices granted access while MDM server unavailable
bull If device is granted a ldquofail openrdquo or other limited access state (for example URL-redirected to MDM) user can hit Continue button when MDM is back online to trigger CoA

bull Problem Statement To register iOS and Android devices for BYOD or MDM they may require Internet access for either downloading supplicant software or for device validation from highly dynamic sources like iTunes and Google Play Same applies for MDM marked non-compliant devices In contrast WLC URL redirection ACL only offers static IP-based rule definition
bull Workaround (works also with older WLC versions eg 741300)
a) Permit full Internet access denyredirect only internal IP address ranges
b) Permit access to Apple and Google IP ranges denyredirect other traffic
c) Fake DNS resolutionbull Optional Plus external DNS-based network access enforcement (ASA WSA or others)

attribute entry for each interface IP address used for URL-
redirected Web services
copy 2015 Cisco andor its affiliates All rights reservedBRKSEC-2035 Cisco Public
bull Problem Statement Any change to interface IP addressing (network relocation vMotion network infrastructure changes etc) requires new certificates to be generated with SAN attributes updated for new IP addresses
ndash Time-consuming process
ndash New certificates signed by 3rd-party CAs can be expensive
ndash Disruption to application services after new cert loaded
bull Solution
ndash Interface Alias Optionally assign ISE node interface (eth1 eth2 eth3) a unique hostnameFQDN which can be resolved to its local IP address using DNS
ndash Each PSN tracks which interfaces are enabled for each service and dynamically substitutes IP variable for URL redirection to the PSNs local interface alias (hostname + domain)

FQDN in SAN
60
bull Problem Statement Every ISE node requires a unique certificate
ndash New certificates signed by 3rd-party CAs can be expensive
ndash Time-consuming process to generate new certs each time new node added
ndash Certificate SAN must include FQDN entry for other web services (Sponsor MDP etc)
ndash Some endpoints require each PSN cert to be trusted and will prompt user to accept
bull Solution Wildcard Certificates
ndash Allows multiple ISE nodes to share single certificate for WebEAP authentication
ndash No longer requires custom SAN with node FQDN or interface IP addresses
ndash Most seamless and improved end-user experience
bull Considerations
ndash Less secure than unique certificate per node greater care to safeguard private key
ndash Limit exposure and deploy ISE into subdomain eg isecompanycom

Key business driver for multi-interface support is traffic separation and assumption that traffic for one service that enters on interface X will return from the interfacenetwork path
bull Problem Statement
ndash Packets received on any ISE interface relies on CARS routing table to determine egress interface and next hop address
bull Solution
ndash Static routes for each endpoint subnet must be configured on each node using CLI to use the desired web service interface
ndash Source NAT to Web Portal interfaces and configure static route to NATrsquoed network
bull Considerations
ndash If NAT not used then depending on network size and addressing complexity may require hundreds of static routes to be configured very difficult to manage and maintain
ndash Dedicated interface for Anchor Controller use case should not be impacted since client IP is local (L2 adjacent) to dedicated ISE interface in DMZ

Connection Messages Explanation
Connection Failed
Please check the connection
parameters
A routing or firewall problem exists between the ISE located in the data center and the MDM located in either the
DMZ or Cloud The firewalls configuration should be checked to confirm HTTPS is allowed in this direction
Connection Failed
404 Not Found
The most likely cause of an HTML 404 error code is that an instance was configured when it was not required or
that the wrong instance has been configured
Connection Failed
403 Forbidden
The user account setup on the MDM server does not have the proper roles associated to it Validate that the
account being used by ISE is assigned the REST API MDM role
Connection Failed
401 UnauthorizedThe user name or password is not correct for the account being used by ISE
Connection Failed There is a
problem with the server
certificate or ISE Trust store
ISE does not trust the certificate presented by the MDM website This indicates the certificate was not imported to
the ISE certificate store or the certificate has expired since it was imported
The MDM Server details are
valid and the connectivity was
successful
The connection has successfully been tested The administrator should also verify the MDM AUTHZ dictionary
has been populated with attributes

Passive Reassessment
bull Bulk recheck against MDM server using configurable timer (polling interval)
bull If result of periodic recheck shows that a connected endpoint is no longer compliant ISE sends a CoA to terminate session
Survivability
bull CoA is NOT sent for devices granted access while MDM server unavailable
bull If device is granted a ldquofail openrdquo or other limited access state (for example URL-redirected to MDM) user can hit Continue button when MDM is back online to trigger CoA

bull Problem Statement To register iOS and Android devices for BYOD or MDM they may require Internet access for either downloading supplicant software or for device validation from highly dynamic sources like iTunes and Google Play Same applies for MDM marked non-compliant devices In contrast WLC URL redirection ACL only offers static IP-based rule definition
bull Workaround (works also with older WLC versions eg 741300)
a) Permit full Internet access denyredirect only internal IP address ranges
b) Permit access to Apple and Google IP ranges denyredirect other traffic
c) Fake DNS resolutionbull Optional Plus external DNS-based network access enforcement (ASA WSA or others)

copy 2015 Cisco andor its affiliates All rights reservedBRKSEC-2035 Cisco Public
bull Problem Statement Any change to interface IP addressing (network relocation vMotion network infrastructure changes etc) requires new certificates to be generated with SAN attributes updated for new IP addresses
ndash Time-consuming process
ndash New certificates signed by 3rd-party CAs can be expensive
ndash Disruption to application services after new cert loaded
bull Solution
ndash Interface Alias Optionally assign ISE node interface (eth1 eth2 eth3) a unique hostnameFQDN which can be resolved to its local IP address using DNS
ndash Each PSN tracks which interfaces are enabled for each service and dynamically substitutes IP variable for URL redirection to the PSNs local interface alias (hostname + domain)
bull Considerations
ndash Manual configuration process from CLI
ndash Requires DNS to be updates for each alias

FQDN in SAN
60
bull Problem Statement Every ISE node requires a unique certificate
ndash New certificates signed by 3rd-party CAs can be expensive
ndash Time-consuming process to generate new certs each time new node added
ndash Certificate SAN must include FQDN entry for other web services (Sponsor MDP etc)
ndash Some endpoints require each PSN cert to be trusted and will prompt user to accept
bull Solution Wildcard Certificates
ndash Allows multiple ISE nodes to share single certificate for WebEAP authentication
ndash No longer requires custom SAN with node FQDN or interface IP addresses
ndash Most seamless and improved end-user experience
bull Considerations
ndash Less secure than unique certificate per node greater care to safeguard private key
ndash Limit exposure and deploy ISE into subdomain eg isecompanycom

Key business driver for multi-interface support is traffic separation and assumption that traffic for one service that enters on interface X will return from the interfacenetwork path
bull Problem Statement
ndash Packets received on any ISE interface relies on CARS routing table to determine egress interface and next hop address
bull Solution
ndash Static routes for each endpoint subnet must be configured on each node using CLI to use the desired web service interface
ndash Source NAT to Web Portal interfaces and configure static route to NATrsquoed network
bull Considerations
ndash If NAT not used then depending on network size and addressing complexity may require hundreds of static routes to be configured very difficult to manage and maintain
ndash Dedicated interface for Anchor Controller use case should not be impacted since client IP is local (L2 adjacent) to dedicated ISE interface in DMZ

Connection Messages Explanation
Connection Failed
Please check the connection
parameters
A routing or firewall problem exists between the ISE located in the data center and the MDM located in either the
DMZ or Cloud The firewalls configuration should be checked to confirm HTTPS is allowed in this direction
Connection Failed
404 Not Found
The most likely cause of an HTML 404 error code is that an instance was configured when it was not required or
that the wrong instance has been configured
Connection Failed
403 Forbidden
The user account setup on the MDM server does not have the proper roles associated to it Validate that the
account being used by ISE is assigned the REST API MDM role
Connection Failed
401 UnauthorizedThe user name or password is not correct for the account being used by ISE
Connection Failed There is a
problem with the server
certificate or ISE Trust store
ISE does not trust the certificate presented by the MDM website This indicates the certificate was not imported to
the ISE certificate store or the certificate has expired since it was imported
The MDM Server details are
valid and the connectivity was
successful
The connection has successfully been tested The administrator should also verify the MDM AUTHZ dictionary
has been populated with attributes

bull Problem Statement To register iOS and Android devices for BYOD or MDM they may require Internet access for either downloading supplicant software or for device validation from highly dynamic sources like iTunes and Google Play Same applies for MDM marked non-compliant devices In contrast WLC URL redirection ACL only offers static IP-based rule definition
bull Workaround (works also with older WLC versions eg 741300)
a) Permit full Internet access denyredirect only internal IP address ranges
b) Permit access to Apple and Google IP ranges denyredirect other traffic
c) Fake DNS resolutionbull Optional Plus external DNS-based network access enforcement (ASA WSA or others)

copy 2015 Cisco andor its affiliates All rights reservedBRKSEC-2035 Cisco Public
bull Problem Statement Any change to interface IP addressing (network relocation vMotion network infrastructure changes etc) requires new certificates to be generated with SAN attributes updated for new IP addresses
ndash Time-consuming process
ndash New certificates signed by 3rd-party CAs can be expensive
ndash Disruption to application services after new cert loaded
bull Solution
ndash Interface Alias Optionally assign ISE node interface (eth1 eth2 eth3) a unique hostnameFQDN which can be resolved to its local IP address using DNS
ndash Each PSN tracks which interfaces are enabled for each service and dynamically substitutes IP variable for URL redirection to the PSNs local interface alias (hostname + domain)

FQDN in SAN
60
bull Problem Statement Every ISE node requires a unique certificate
ndash New certificates signed by 3rd-party CAs can be expensive
ndash Time-consuming process to generate new certs each time new node added
ndash Certificate SAN must include FQDN entry for other web services (Sponsor MDP etc)
ndash Some endpoints require each PSN cert to be trusted and will prompt user to accept
bull Solution Wildcard Certificates
ndash Allows multiple ISE nodes to share single certificate for WebEAP authentication
ndash No longer requires custom SAN with node FQDN or interface IP addresses
ndash Most seamless and improved end-user experience
bull Considerations
ndash Less secure than unique certificate per node greater care to safeguard private key
ndash Limit exposure and deploy ISE into subdomain eg isecompanycom

Key business driver for multi-interface support is traffic separation and assumption that traffic for one service that enters on interface X will return from the interfacenetwork path
bull Problem Statement
ndash Packets received on any ISE interface relies on CARS routing table to determine egress interface and next hop address
bull Solution
ndash Static routes for each endpoint subnet must be configured on each node using CLI to use the desired web service interface
ndash Source NAT to Web Portal interfaces and configure static route to NATrsquoed network
bull Considerations
ndash If NAT not used then depending on network size and addressing complexity may require hundreds of static routes to be configured very difficult to manage and maintain
ndash Dedicated interface for Anchor Controller use case should not be impacted since client IP is local (L2 adjacent) to dedicated ISE interface in DMZ

Connection Messages Explanation
Connection Failed
Please check the connection
parameters
A routing or firewall problem exists between the ISE located in the data center and the MDM located in either the
DMZ or Cloud The firewalls configuration should be checked to confirm HTTPS is allowed in this direction
Connection Failed
404 Not Found
The most likely cause of an HTML 404 error code is that an instance was configured when it was not required or
that the wrong instance has been configured
Connection Failed
403 Forbidden
The user account setup on the MDM server does not have the proper roles associated to it Validate that the
account being used by ISE is assigned the REST API MDM role
Connection Failed
401 UnauthorizedThe user name or password is not correct for the account being used by ISE
Connection Failed There is a
problem with the server
certificate or ISE Trust store
ISE does not trust the certificate presented by the MDM website This indicates the certificate was not imported to
the ISE certificate store or the certificate has expired since it was imported
The MDM Server details are
valid and the connectivity was
successful
The connection has successfully been tested The administrator should also verify the MDM AUTHZ dictionary
has been populated with attributes

ISE ndash MDM IntegrationScalability
bull Scalability = 30 API calls per second ( gt100`000 callsh)Consider Internet bandwidth and latency for cloud-based solutions
Passive Reassessment
bull Bulk recheck against MDM server using configurable timer (polling interval)
bull If result of periodic recheck shows that a connected endpoint is no longer compliant ISE sends a CoA to terminate session
Survivability
bull CoA is NOT sent for devices granted access while MDM server unavailable
bull If device is granted a ldquofail openrdquo or other limited access state (for example URL-redirected to MDM) user can hit Continue button when MDM is back online to trigger CoA

bull Problem Statement To register iOS and Android devices for BYOD or MDM they may require Internet access for either downloading supplicant software or for device validation from highly dynamic sources like iTunes and Google Play Same applies for MDM marked non-compliant devices In contrast WLC URL redirection ACL only offers static IP-based rule definition
bull Workaround (works also with older WLC versions eg 741300)
a) Permit full Internet access denyredirect only internal IP address ranges
b) Permit access to Apple and Google IP ranges denyredirect other traffic
c) Fake DNS resolutionbull Optional Plus external DNS-based network access enforcement (ASA WSA or others)

bull Problem Statement Any change to interface IP addressing (network relocation vMotion network infrastructure changes etc) requires new certificates to be generated with SAN attributes updated for new IP addresses
ndash Time-consuming process
ndash New certificates signed by 3rd-party CAs can be expensive
ndash Disruption to application services after new cert loaded
bull Solution
ndash Interface Alias Optionally assign ISE node interface (eth1 eth2 eth3) a unique hostnameFQDN which can be resolved to its local IP address using DNS
ndash Each PSN tracks which interfaces are enabled for each service and dynamically substitutes IP variable for URL redirection to the PSNs local interface alias (hostname + domain)
bull Considerations
ndash Manual configuration process from CLI
ndash Requires DNS to be updates for each alias

FQDN in SAN
60
bull Problem Statement Every ISE node requires a unique certificate
ndash New certificates signed by 3rd-party CAs can be expensive
ndash Time-consuming process to generate new certs each time new node added
ndash Certificate SAN must include FQDN entry for other web services (Sponsor MDP etc)
ndash Some endpoints require each PSN cert to be trusted and will prompt user to accept
bull Solution Wildcard Certificates
ndash Allows multiple ISE nodes to share single certificate for WebEAP authentication
ndash No longer requires custom SAN with node FQDN or interface IP addresses
ndash Most seamless and improved end-user experience
bull Considerations
ndash Less secure than unique certificate per node greater care to safeguard private key
ndash Limit exposure and deploy ISE into subdomain eg isecompanycom

Key business driver for multi-interface support is traffic separation and assumption that traffic for one service that enters on interface X will return from the interfacenetwork path
bull Problem Statement
ndash Packets received on any ISE interface relies on CARS routing table to determine egress interface and next hop address
bull Solution
ndash Static routes for each endpoint subnet must be configured on each node using CLI to use the desired web service interface
ndash Source NAT to Web Portal interfaces and configure static route to NATrsquoed network
bull Considerations
ndash If NAT not used then depending on network size and addressing complexity may require hundreds of static routes to be configured very difficult to manage and maintain
ndash Dedicated interface for Anchor Controller use case should not be impacted since client IP is local (L2 adjacent) to dedicated ISE interface in DMZ

Connection Messages Explanation
Connection Failed
Please check the connection
parameters
A routing or firewall problem exists between the ISE located in the data center and the MDM located in either the
DMZ or Cloud The firewalls configuration should be checked to confirm HTTPS is allowed in this direction
Connection Failed
404 Not Found
The most likely cause of an HTML 404 error code is that an instance was configured when it was not required or
that the wrong instance has been configured
Connection Failed
403 Forbidden
The user account setup on the MDM server does not have the proper roles associated to it Validate that the
account being used by ISE is assigned the REST API MDM role
Connection Failed
401 UnauthorizedThe user name or password is not correct for the account being used by ISE
Connection Failed There is a
problem with the server
certificate or ISE Trust store
ISE does not trust the certificate presented by the MDM website This indicates the certificate was not imported to
the ISE certificate store or the certificate has expired since it was imported
The MDM Server details are
valid and the connectivity was
successful
The connection has successfully been tested The administrator should also verify the MDM AUTHZ dictionary
has been populated with attributes

Passive Reassessment
bull Bulk recheck against MDM server using configurable timer (polling interval)
bull If result of periodic recheck shows that a connected endpoint is no longer compliant ISE sends a CoA to terminate session
Survivability
bull CoA is NOT sent for devices granted access while MDM server unavailable
bull If device is granted a ldquofail openrdquo or other limited access state (for example URL-redirected to MDM) user can hit Continue button when MDM is back online to trigger CoA

ndash Pre-Auth DNS-based ACL enhancement
ndash iOS7 Captive Network Assistant (CNA) behavior change
ndash Stability improvements
bull AirOS 74130
ndash Alternative AirOS release containing most ISE ndash MDM Integration related features and stability improvements
ndash Missing Pre-Auth DNS-based ACL enhancementTherefore the first proposed implementation option later in this deck ldquoPre-Auth DNS-based ACLrdquo isnrsquot applicable
bull A note to converged access controllers

WLC ndash URL Redirection ACL
bull Problem Statement To register iOS and Android devices for BYOD or MDM they may require Internet access for either downloading supplicant software or for device validation from highly dynamic sources like iTunes and Google Play Same applies for MDM marked non-compliant devices In contrast WLC URL redirection ACL only offers static IP-based rule definition
bull Workaround (works also with older WLC versions eg 741300)
a) Permit full Internet access denyredirect only internal IP address ranges
b) Permit access to Apple and Google IP ranges denyredirect other traffic
c) Fake DNS resolutionbull Optional Plus external DNS-based network access enforcement (ASA WSA or others)
d) Out-of-band MDM onboarding just do endpoint compliance checking

attribute entry for each interface IP address used for URL-

copy 2015 Cisco andor its affiliates All rights reservedBRKSEC-2035 Cisco Public
bull Problem Statement Any change to interface IP addressing (network relocation vMotion network infrastructure changes etc) requires new certificates to be generated with SAN attributes updated for new IP addresses
ndash Time-consuming process
ndash New certificates signed by 3rd-party CAs can be expensive
ndash Disruption to application services after new cert loaded
bull Solution
ndash Interface Alias Optionally assign ISE node interface (eth1 eth2 eth3) a unique hostnameFQDN which can be resolved to its local IP address using DNS
ndash Each PSN tracks which interfaces are enabled for each service and dynamically substitutes IP variable for URL redirection to the PSNs local interface alias (hostname + domain)
bull Considerations
ndash Manual configuration process from CLI
ndash Requires DNS to be updates for each alias

FQDN in SAN
60
bull Problem Statement Every ISE node requires a unique certificate
ndash New certificates signed by 3rd-party CAs can be expensive
ndash Time-consuming process to generate new certs each time new node added
ndash Certificate SAN must include FQDN entry for other web services (Sponsor MDP etc)
ndash Some endpoints require each PSN cert to be trusted and will prompt user to accept
bull Solution Wildcard Certificates
ndash Allows multiple ISE nodes to share single certificate for WebEAP authentication
ndash No longer requires custom SAN with node FQDN or interface IP addresses
ndash Most seamless and improved end-user experience
bull Considerations
ndash Less secure than unique certificate per node greater care to safeguard private key
ndash Limit exposure and deploy ISE into subdomain eg isecompanycom

Key business driver for multi-interface support is traffic separation and assumption that traffic for one service that enters on interface X will return from the interfacenetwork path
bull Problem Statement
ndash Packets received on any ISE interface relies on CARS routing table to determine egress interface and next hop address
bull Solution
ndash Static routes for each endpoint subnet must be configured on each node using CLI to use the desired web service interface
ndash Source NAT to Web Portal interfaces and configure static route to NATrsquoed network
bull Considerations
ndash If NAT not used then depending on network size and addressing complexity may require hundreds of static routes to be configured very difficult to manage and maintain
ndash Dedicated interface for Anchor Controller use case should not be impacted since client IP is local (L2 adjacent) to dedicated ISE interface in DMZ

Connection Messages Explanation
Connection Failed
Please check the connection
parameters
A routing or firewall problem exists between the ISE located in the data center and the MDM located in either the
DMZ or Cloud The firewalls configuration should be checked to confirm HTTPS is allowed in this direction
Connection Failed
404 Not Found
The most likely cause of an HTML 404 error code is that an instance was configured when it was not required or
that the wrong instance has been configured
Connection Failed
403 Forbidden
The user account setup on the MDM server does not have the proper roles associated to it Validate that the
account being used by ISE is assigned the REST API MDM role
Connection Failed
401 UnauthorizedThe user name or password is not correct for the account being used by ISE
Connection Failed There is a
problem with the server
certificate or ISE Trust store
ISE does not trust the certificate presented by the MDM website This indicates the certificate was not imported to
the ISE certificate store or the certificate has expired since it was imported
The MDM Server details are
valid and the connectivity was
successful
The connection has successfully been tested The administrator should also verify the MDM AUTHZ dictionary
has been populated with attributes

ISE ndash MDM IntegrationScalability
bull Scalability = 30 API calls per second ( gt100`000 callsh)Consider Internet bandwidth and latency for cloud-based solutions
Passive Reassessment
bull Bulk recheck against MDM server using configurable timer (polling interval)
bull If result of periodic recheck shows that a connected endpoint is no longer compliant ISE sends a CoA to terminate session
Survivability
bull CoA is NOT sent for devices granted access while MDM server unavailable
bull If device is granted a ldquofail openrdquo or other limited access state (for example URL-redirected to MDM) user can hit Continue button when MDM is back online to trigger CoA

bull Problem Statement To register iOS and Android devices for BYOD or MDM they may require Internet access for either downloading supplicant software or for device validation from highly dynamic sources like iTunes and Google Play Same applies for MDM marked non-compliant devices In contrast WLC URL redirection ACL only offers static IP-based rule definition
bull Workaround (works also with older WLC versions eg 741300)
a) Permit full Internet access denyredirect only internal IP address ranges
b) Permit access to Apple and Google IP ranges denyredirect other traffic

copy 2015 Cisco andor its affiliates All rights reservedBRKSEC-2035 Cisco Public

ndash Time-consuming process
ndash New certificates signed by 3rd-party CAs can be expensive
ndash Disruption to application services after new cert loaded
bull Solution
ndash Interface Alias Optionally assign ISE node interface (eth1 eth2 eth3) a unique hostnameFQDN which can be resolved to its local IP address using DNS
ndash Each PSN tracks which interfaces are enabled for each service and dynamically substitutes IP variable for URL redirection to the PSNs local interface alias (hostname + domain)

FQDN in SAN
60
bull Problem Statement Every ISE node requires a unique certificate
ndash New certificates signed by 3rd-party CAs can be expensive
ndash Time-consuming process to generate new certs each time new node added
ndash Certificate SAN must include FQDN entry for other web services (Sponsor MDP etc)
ndash Some endpoints require each PSN cert to be trusted and will prompt user to accept
bull Solution Wildcard Certificates
ndash Allows multiple ISE nodes to share single certificate for WebEAP authentication
ndash No longer requires custom SAN with node FQDN or interface IP addresses
ndash Most seamless and improved end-user experience
bull Considerations
ndash Less secure than unique certificate per node greater care to safeguard private key
ndash Limit exposure and deploy ISE into subdomain eg isecompanycom

Key business driver for multi-interface support is traffic separation and assumption that traffic for one service that enters on interface X will return from the interfacenetwork path
bull Problem Statement
ndash Packets received on any ISE interface relies on CARS routing table to determine egress interface and next hop address
bull Solution
ndash Static routes for each endpoint subnet must be configured on each node using CLI to use the desired web service interface
ndash Source NAT to Web Portal interfaces and configure static route to NATrsquoed network
bull Considerations
ndash If NAT not used then depending on network size and addressing complexity may require hundreds of static routes to be configured very difficult to manage and maintain
ndash Dedicated interface for Anchor Controller use case should not be impacted since client IP is local (L2 adjacent) to dedicated ISE interface in DMZ

Connection Messages Explanation
Connection Failed
Please check the connection
parameters
A routing or firewall problem exists between the ISE located in the data center and the MDM located in either the
DMZ or Cloud The firewalls configuration should be checked to confirm HTTPS is allowed in this direction
Connection Failed
404 Not Found
The most likely cause of an HTML 404 error code is that an instance was configured when it was not required or
that the wrong instance has been configured
Connection Failed
403 Forbidden
The user account setup on the MDM server does not have the proper roles associated to it Validate that the
account being used by ISE is assigned the REST API MDM role
Connection Failed
401 UnauthorizedThe user name or password is not correct for the account being used by ISE
Connection Failed There is a
problem with the server
certificate or ISE Trust store
ISE does not trust the certificate presented by the MDM website This indicates the certificate was not imported to
the ISE certificate store or the certificate has expired since it was imported
The MDM Server details are
valid and the connectivity was
successful
The connection has successfully been tested The administrator should also verify the MDM AUTHZ dictionary
has been populated with attributes

bull Scalability = 30 API calls per second ( gt100`000 callsh)Consider Internet bandwidth and latency for cloud-based solutions
Passive Reassessment
bull Bulk recheck against MDM server using configurable timer (polling interval)
bull If result of periodic recheck shows that a connected endpoint is no longer compliant ISE sends a CoA to terminate session
Survivability
bull CoA is NOT sent for devices granted access while MDM server unavailable
bull If device is granted a ldquofail openrdquo or other limited access state (for example URL-redirected to MDM) user can hit Continue button when MDM is back online to trigger CoA

bull Problem Statement To register iOS and Android devices for BYOD or MDM they may require Internet access for either downloading supplicant software or for device validation from highly dynamic sources like iTunes and Google Play Same applies for MDM marked non-compliant devices In contrast WLC URL redirection ACL only offers static IP-based rule definition
bull Workaround (works also with older WLC versions eg 741300)
a) Permit full Internet access denyredirect only internal IP address ranges
b) Permit access to Apple and Google IP ranges denyredirect other traffic
c) Fake DNS resolutionbull Optional Plus external DNS-based network access enforcement (ASA WSA or others)
d) Out-of-band MDM onboarding just do endpoint compliance checking

copy 2015 Cisco andor its affiliates All rights reservedBRKSEC-2035 Cisco Public
bull Problem Statement Any change to interface IP addressing (network relocation vMotion network infrastructure changes etc) requires new certificates to be generated with SAN attributes updated for new IP addresses
ndash Time-consuming process
ndash New certificates signed by 3rd-party CAs can be expensive
ndash Disruption to application services after new cert loaded
bull Solution
ndash Interface Alias Optionally assign ISE node interface (eth1 eth2 eth3) a unique hostnameFQDN which can be resolved to its local IP address using DNS
ndash Each PSN tracks which interfaces are enabled for each service and dynamically substitutes IP variable for URL redirection to the PSNs local interface alias (hostname + domain)
bull Considerations
ndash Manual configuration process from CLI
ndash Requires DNS to be updates for each alias

FQDN in SAN
60
bull Problem Statement Every ISE node requires a unique certificate
ndash New certificates signed by 3rd-party CAs can be expensive
ndash Time-consuming process to generate new certs each time new node added
ndash Certificate SAN must include FQDN entry for other web services (Sponsor MDP etc)
ndash Some endpoints require each PSN cert to be trusted and will prompt user to accept
bull Solution Wildcard Certificates
ndash Allows multiple ISE nodes to share single certificate for WebEAP authentication
ndash No longer requires custom SAN with node FQDN or interface IP addresses
ndash Most seamless and improved end-user experience
bull Considerations
ndash Less secure than unique certificate per node greater care to safeguard private key
ndash Limit exposure and deploy ISE into subdomain eg isecompanycom

Key business driver for multi-interface support is traffic separation and assumption that traffic for one service that enters on interface X will return from the interfacenetwork path
bull Problem Statement
ndash Packets received on any ISE interface relies on CARS routing table to determine egress interface and next hop address
bull Solution
ndash Static routes for each endpoint subnet must be configured on each node using CLI to use the desired web service interface
ndash Source NAT to Web Portal interfaces and configure static route to NATrsquoed network
bull Considerations
ndash If NAT not used then depending on network size and addressing complexity may require hundreds of static routes to be configured very difficult to manage and maintain
ndash Dedicated interface for Anchor Controller use case should not be impacted since client IP is local (L2 adjacent) to dedicated ISE interface in DMZ

Connection Messages Explanation
Connection Failed
Please check the connection
parameters
A routing or firewall problem exists between the ISE located in the data center and the MDM located in either the
DMZ or Cloud The firewalls configuration should be checked to confirm HTTPS is allowed in this direction
Connection Failed
404 Not Found
The most likely cause of an HTML 404 error code is that an instance was configured when it was not required or
that the wrong instance has been configured
Connection Failed
403 Forbidden
The user account setup on the MDM server does not have the proper roles associated to it Validate that the
account being used by ISE is assigned the REST API MDM role
Connection Failed
401 UnauthorizedThe user name or password is not correct for the account being used by ISE
Connection Failed There is a
problem with the server
certificate or ISE Trust store
ISE does not trust the certificate presented by the MDM website This indicates the certificate was not imported to
the ISE certificate store or the certificate has expired since it was imported
The MDM Server details are
valid and the connectivity was
successful
The connection has successfully been tested The administrator should also verify the MDM AUTHZ dictionary
has been populated with attributes

Passive Reassessment
bull Bulk recheck against MDM server using configurable timer (polling interval)
bull If result of periodic recheck shows that a connected endpoint is no longer compliant ISE sends a CoA to terminate session
Survivability
bull CoA is NOT sent for devices granted access while MDM server unavailable
bull If device is granted a ldquofail openrdquo or other limited access state (for example URL-redirected to MDM) user can hit Continue button when MDM is back online to trigger CoA

WLC ndash URL Redirection ACL
bull Problem Statement To register iOS and Android devices for BYOD or MDM they may require Internet access for either downloading supplicant software or for device validation from highly dynamic sources like iTunes and Google Play Same applies for MDM marked non-compliant devices In contrast WLC URL redirection ACL only offers static IP-based rule definition
bull Workaround (works also with older WLC versions eg 741300)
a) Permit full Internet access denyredirect only internal IP address ranges
b) Permit access to Apple and Google IP ranges denyredirect other traffic
c) Fake DNS resolutionbull Optional Plus external DNS-based network access enforcement (ASA WSA or others)
d) Out-of-band MDM onboarding just do endpoint compliance checking

copy 2015 Cisco andor its affiliates All rights reservedBRKSEC-2035 Cisco Public
bull Problem Statement Any change to interface IP addressing (network relocation vMotion network infrastructure changes etc) requires new certificates to be generated with SAN attributes updated for new IP addresses
ndash Time-consuming process
ndash New certificates signed by 3rd-party CAs can be expensive
ndash Disruption to application services after new cert loaded
bull Solution
ndash Interface Alias Optionally assign ISE node interface (eth1 eth2 eth3) a unique hostnameFQDN which can be resolved to its local IP address using DNS
ndash Each PSN tracks which interfaces are enabled for each service and dynamically substitutes IP variable for URL redirection to the PSNs local interface alias (hostname + domain)
bull Considerations

FQDN in SAN
60
bull Problem Statement Every ISE node requires a unique certificate
ndash New certificates signed by 3rd-party CAs can be expensive
ndash Time-consuming process to generate new certs each time new node added
ndash Certificate SAN must include FQDN entry for other web services (Sponsor MDP etc)
ndash Some endpoints require each PSN cert to be trusted and will prompt user to accept
bull Solution Wildcard Certificates
ndash Allows multiple ISE nodes to share single certificate for WebEAP authentication
ndash No longer requires custom SAN with node FQDN or interface IP addresses
ndash Most seamless and improved end-user experience
bull Considerations
ndash Less secure than unique certificate per node greater care to safeguard private key
ndash Limit exposure and deploy ISE into subdomain eg isecompanycom

Key business driver for multi-interface support is traffic separation and assumption that traffic for one service that enters on interface X will return from the interfacenetwork path
bull Problem Statement
ndash Packets received on any ISE interface relies on CARS routing table to determine egress interface and next hop address
bull Solution
ndash Static routes for each endpoint subnet must be configured on each node using CLI to use the desired web service interface
ndash Source NAT to Web Portal interfaces and configure static route to NATrsquoed network
bull Considerations
ndash If NAT not used then depending on network size and addressing complexity may require hundreds of static routes to be configured very difficult to manage and maintain
ndash Dedicated interface for Anchor Controller use case should not be impacted since client IP is local (L2 adjacent) to dedicated ISE interface in DMZ

Connection Messages Explanation
Connection Failed
Please check the connection
parameters
A routing or firewall problem exists between the ISE located in the data center and the MDM located in either the
DMZ or Cloud The firewalls configuration should be checked to confirm HTTPS is allowed in this direction
Connection Failed
404 Not Found
The most likely cause of an HTML 404 error code is that an instance was configured when it was not required or
that the wrong instance has been configured
Connection Failed
403 Forbidden
The user account setup on the MDM server does not have the proper roles associated to it Validate that the
account being used by ISE is assigned the REST API MDM role
Connection Failed
401 UnauthorizedThe user name or password is not correct for the account being used by ISE
Connection Failed There is a
problem with the server
certificate or ISE Trust store
ISE does not trust the certificate presented by the MDM website This indicates the certificate was not imported to
the ISE certificate store or the certificate has expired since it was imported
The MDM Server details are
valid and the connectivity was
successful
The connection has successfully been tested The administrator should also verify the MDM AUTHZ dictionary
has been populated with attributes

Passive Reassessment
bull Bulk recheck against MDM server using configurable timer (polling interval)
bull If result of periodic recheck shows that a connected endpoint is no longer compliant ISE sends a CoA to terminate session
Survivability
bull CoA is NOT sent for devices granted access while MDM server unavailable
bull If device is granted a ldquofail openrdquo or other limited access state (for example URL-redirected to MDM) user can hit Continue button when MDM is back online to trigger CoA

bull Problem Statement To register iOS and Android devices for BYOD or MDM they may require Internet access for either downloading supplicant software or for device validation from highly dynamic sources like iTunes and Google Play Same applies for MDM marked non-compliant devices In contrast WLC URL redirection ACL only offers static IP-based rule definition
bull Workaround (works also with older WLC versions eg 741300)
a) Permit full Internet access denyredirect only internal IP address ranges
b) Permit access to Apple and Google IP ranges denyredirect other traffic
c) Fake DNS resolutionbull Optional Plus external DNS-based network access enforcement (ASA WSA or others)

copy 2015 Cisco andor its affiliates All rights reservedBRKSEC-2035 Cisco Public
bull Problem Statement Any change to interface IP addressing (network relocation vMotion network infrastructure changes etc) requires new certificates to be generated with SAN attributes updated for new IP addresses
ndash Time-consuming process
ndash New certificates signed by 3rd-party CAs can be expensive
ndash Disruption to application services after new cert loaded
bull Solution
ndash Interface Alias Optionally assign ISE node interface (eth1 eth2 eth3) a unique hostnameFQDN which can be resolved to its local IP address using DNS
ndash Each PSN tracks which interfaces are enabled for each service and dynamically substitutes IP variable for URL redirection to the PSNs local interface alias (hostname + domain)
bull Considerations

FQDN in SAN
60
bull Problem Statement Every ISE node requires a unique certificate
ndash New certificates signed by 3rd-party CAs can be expensive
ndash Time-consuming process to generate new certs each time new node added
ndash Certificate SAN must include FQDN entry for other web services (Sponsor MDP etc)
ndash Some endpoints require each PSN cert to be trusted and will prompt user to accept
bull Solution Wildcard Certificates
ndash Allows multiple ISE nodes to share single certificate for WebEAP authentication
ndash No longer requires custom SAN with node FQDN or interface IP addresses
ndash Most seamless and improved end-user experience
bull Considerations
ndash Less secure than unique certificate per node greater care to safeguard private key
ndash Limit exposure and deploy ISE into subdomain eg isecompanycom

Key business driver for multi-interface support is traffic separation and assumption that traffic for one service that enters on interface X will return from the interfacenetwork path
bull Problem Statement
ndash Packets received on any ISE interface relies on CARS routing table to determine egress interface and next hop address
bull Solution
ndash Static routes for each endpoint subnet must be configured on each node using CLI to use the desired web service interface
ndash Source NAT to Web Portal interfaces and configure static route to NATrsquoed network
bull Considerations
ndash If NAT not used then depending on network size and addressing complexity may require hundreds of static routes to be configured very difficult to manage and maintain
ndash Dedicated interface for Anchor Controller use case should not be impacted since client IP is local (L2 adjacent) to dedicated ISE interface in DMZ

Connection Messages Explanation
Connection Failed
Please check the connection
parameters
A routing or firewall problem exists between the ISE located in the data center and the MDM located in either the
DMZ or Cloud The firewalls configuration should be checked to confirm HTTPS is allowed in this direction
Connection Failed
404 Not Found
The most likely cause of an HTML 404 error code is that an instance was configured when it was not required or
that the wrong instance has been configured
Connection Failed
403 Forbidden
The user account setup on the MDM server does not have the proper roles associated to it Validate that the
account being used by ISE is assigned the REST API MDM role
Connection Failed
401 UnauthorizedThe user name or password is not correct for the account being used by ISE
Connection Failed There is a
problem with the server
certificate or ISE Trust store
ISE does not trust the certificate presented by the MDM website This indicates the certificate was not imported to
the ISE certificate store or the certificate has expired since it was imported
The MDM Server details are
valid and the connectivity was
successful
The connection has successfully been tested The administrator should also verify the MDM AUTHZ dictionary
has been populated with attributes

Passive Reassessment
bull Bulk recheck against MDM server using configurable timer (polling interval)
bull If result of periodic recheck shows that a connected endpoint is no longer compliant ISE sends a CoA to terminate session
Survivability
bull CoA is NOT sent for devices granted access while MDM server unavailable
bull If device is granted a ldquofail openrdquo or other limited access state (for example URL-redirected to MDM) user can hit Continue button when MDM is back online to trigger CoA

bull Problem Statement To register iOS and Android devices for BYOD or MDM they may require Internet access for either downloading supplicant software or for device validation from highly dynamic sources like iTunes and Google Play Same applies for MDM marked non-compliant devices In contrast WLC URL redirection ACL only offers static IP-based rule definition
bull Workaround (works also with older WLC versions eg 741300)
a) Permit full Internet access denyredirect only internal IP address ranges
b) Permit access to Apple and Google IP ranges denyredirect other traffic
c) Fake DNS resolutionbull Optional Plus external DNS-based network access enforcement (ASA WSA or others)

attribute entry for each interface IP address used for URL-
redirected Web services
copy 2015 Cisco andor its affiliates All rights reservedBRKSEC-2035 Cisco Public
bull Problem Statement Any change to interface IP addressing (network relocation vMotion network infrastructure changes etc) requires new certificates to be generated with SAN attributes updated for new IP addresses
ndash Time-consuming process
ndash New certificates signed by 3rd-party CAs can be expensive
ndash Disruption to application services after new cert loaded
bull Solution
ndash Interface Alias Optionally assign ISE node interface (eth1 eth2 eth3) a unique hostnameFQDN which can be resolved to its local IP address using DNS
ndash Each PSN tracks which interfaces are enabled for each service and dynamically substitutes IP variable for URL redirection to the PSNs local interface alias (hostname + domain)
bull Considerations
ndash Manual configuration process from CLI

FQDN in SAN

bull Problem Statement Every ISE node requires a unique certificate
ndash New certificates signed by 3rd-party CAs can be expensive
ndash Time-consuming process to generate new certs each time new node added
ndash Certificate SAN must include FQDN entry for other web services (Sponsor MDP etc)
ndash Some endpoints require each PSN cert to be trusted and will prompt user to accept
bull Solution Wildcard Certificates
ndash Allows multiple ISE nodes to share single certificate for WebEAP authentication
ndash No longer requires custom SAN with node FQDN or interface IP addresses
ndash Most seamless and improved end-user experience
bull Considerations
ndash Less secure than unique certificate per node greater care to safeguard private key
ndash Limit exposure and deploy ISE into subdomain eg isecompanycom

Key business driver for multi-interface support is traffic separation and assumption that traffic for one service that enters on interface X will return from the interfacenetwork path
bull Problem Statement
ndash Packets received on any ISE interface relies on CARS routing table to determine egress interface and next hop address
bull Solution
ndash Static routes for each endpoint subnet must be configured on each node using CLI to use the desired web service interface
ndash Source NAT to Web Portal interfaces and configure static route to NATrsquoed network
bull Considerations
ndash If NAT not used then depending on network size and addressing complexity may require hundreds of static routes to be configured very difficult to manage and maintain
ndash Dedicated interface for Anchor Controller use case should not be impacted since client IP is local (L2 adjacent) to dedicated ISE interface in DMZ

Connection Messages Explanation
Connection Failed
Please check the connection
parameters
A routing or firewall problem exists between the ISE located in the data center and the MDM located in either the
DMZ or Cloud The firewalls configuration should be checked to confirm HTTPS is allowed in this direction
Connection Failed
404 Not Found
The most likely cause of an HTML 404 error code is that an instance was configured when it was not required or
that the wrong instance has been configured
Connection Failed
403 Forbidden
The user account setup on the MDM server does not have the proper roles associated to it Validate that the
account being used by ISE is assigned the REST API MDM role
Connection Failed
401 UnauthorizedThe user name or password is not correct for the account being used by ISE
Connection Failed There is a
problem with the server
certificate or ISE Trust store
ISE does not trust the certificate presented by the MDM website This indicates the certificate was not imported to
the ISE certificate store or the certificate has expired since it was imported
The MDM Server details are
valid and the connectivity was
successful
The connection has successfully been tested The administrator should also verify the MDM AUTHZ dictionary
has been populated with attributes

Passive Reassessment
bull Bulk recheck against MDM server using configurable timer (polling interval)
bull If result of periodic recheck shows that a connected endpoint is no longer compliant ISE sends a CoA to terminate session
Survivability
bull CoA is NOT sent for devices granted access while MDM server unavailable
bull If device is granted a ldquofail openrdquo or other limited access state (for example URL-redirected to MDM) user can hit Continue button when MDM is back online to trigger CoA

bull Problem Statement To register iOS and Android devices for BYOD or MDM they may require Internet access for either downloading supplicant software or for device validation from highly dynamic sources like iTunes and Google Play Same applies for MDM marked non-compliant devices In contrast WLC URL redirection ACL only offers static IP-based rule definition
bull Workaround (works also with older WLC versions eg 741300)
a) Permit full Internet access denyredirect only internal IP address ranges
b) Permit access to Apple and Google IP ranges denyredirect other traffic
c) Fake DNS resolutionbull Optional Plus external DNS-based network access enforcement (ASA WSA or others)

bull ISE 13 or
bull ISE 12 Patch with latest patch (but min patch 6 is recommended)
ndash MDM cachingbull If device connects to network ISE caches the MDM state
bull Next time device attempts to log-on ISE use the cache to allow access per previous MDM check
bull Once the device is on the network ISE checks with MDM using API call if the MDM state has changed (eg compliant -gt non-compliant)
bull If the state has changed ISE issues a COA to give a new policy (as per updated MDM attributes)
bull A note to ISE 13 12 patches
ndash Patches are cumulative
ndash Patches posted roughly on a 4-6 weeks basis

attribute entry for each interface IP address used for URL-
redirected Web services
copy 2015 Cisco andor its affiliates All rights reservedBRKSEC-2035 Cisco Public
bull Problem Statement Any change to interface IP addressing (network relocation vMotion network infrastructure changes etc) requires new certificates to be generated with SAN attributes updated for new IP addresses
ndash Time-consuming process
ndash New certificates signed by 3rd-party CAs can be expensive
ndash Disruption to application services after new cert loaded
bull Solution
ndash Interface Alias Optionally assign ISE node interface (eth1 eth2 eth3) a unique hostnameFQDN which can be resolved to its local IP address using DNS
ndash Each PSN tracks which interfaces are enabled for each service and dynamically substitutes IP variable for URL redirection to the PSNs local interface alias (hostname + domain)
bull Considerations
ndash Manual configuration process from CLI
ndash Requires DNS to be updates for each alias

FQDN in SAN
60
bull Problem Statement Every ISE node requires a unique certificate
ndash New certificates signed by 3rd-party CAs can be expensive
ndash Time-consuming process to generate new certs each time new node added
ndash Certificate SAN must include FQDN entry for other web services (Sponsor MDP etc)
ndash Some endpoints require each PSN cert to be trusted and will prompt user to accept
bull Solution Wildcard Certificates
ndash Allows multiple ISE nodes to share single certificate for WebEAP authentication
ndash No longer requires custom SAN with node FQDN or interface IP addresses
ndash Most seamless and improved end-user experience
bull Considerations
ndash Less secure than unique certificate per node greater care to safeguard private key
ndash Limit exposure and deploy ISE into subdomain eg isecompanycom

Key business driver for multi-interface support is traffic separation and assumption that traffic for one service that enters on interface X will return from the interfacenetwork path
bull Problem Statement
ndash Packets received on any ISE interface relies on CARS routing table to determine egress interface and next hop address
bull Solution
ndash Static routes for each endpoint subnet must be configured on each node using CLI to use the desired web service interface
ndash Source NAT to Web Portal interfaces and configure static route to NATrsquoed network
bull Considerations
ndash If NAT not used then depending on network size and addressing complexity may require hundreds of static routes to be configured very difficult to manage and maintain
ndash Dedicated interface for Anchor Controller use case should not be impacted since client IP is local (L2 adjacent) to dedicated ISE interface in DMZ

Connection Messages Explanation
Connection Failed
Please check the connection
parameters
A routing or firewall problem exists between the ISE located in the data center and the MDM located in either the
DMZ or Cloud The firewalls configuration should be checked to confirm HTTPS is allowed in this direction
Connection Failed
404 Not Found
The most likely cause of an HTML 404 error code is that an instance was configured when it was not required or
that the wrong instance has been configured
Connection Failed
403 Forbidden
The user account setup on the MDM server does not have the proper roles associated to it Validate that the
account being used by ISE is assigned the REST API MDM role
Connection Failed
401 UnauthorizedThe user name or password is not correct for the account being used by ISE
Connection Failed There is a
problem with the server
certificate or ISE Trust store
ISE does not trust the certificate presented by the MDM website This indicates the certificate was not imported to
the ISE certificate store or the certificate has expired since it was imported
The MDM Server details are
valid and the connectivity was
successful
The connection has successfully been tested The administrator should also verify the MDM AUTHZ dictionary
has been populated with attributes

bull Bulk recheck against MDM server using configurable timer (polling interval)
bull If result of periodic recheck shows that a connected endpoint is no longer compliant ISE sends a CoA to terminate session
Survivability
bull CoA is NOT sent for devices granted access while MDM server unavailable

ndash iOS7 Captive Network Assistant (CNA) behavior change
ndash Stability improvements
bull AirOS 74130
ndash Alternative AirOS release containing most ISE ndash MDM Integration related features and stability improvements
ndash Missing Pre-Auth DNS-based ACL enhancementTherefore the first proposed implementation option later in this deck ldquoPre-Auth DNS-based ACLrdquo isnrsquot applicable

bull Problem Statement To register iOS and Android devices for BYOD or MDM they may require Internet access for either downloading supplicant software or for device validation from highly dynamic sources like iTunes and Google Play Same applies for MDM marked non-compliant devices In contrast WLC URL redirection ACL only offers static IP-based rule definition
bull Workaround (works also with older WLC versions eg 741300)
a) Permit full Internet access denyredirect only internal IP address ranges
b) Permit access to Apple and Google IP ranges denyredirect other traffic
c) Fake DNS resolutionbull Optional Plus external DNS-based network access enforcement (ASA WSA or others)
d) Out-of-band MDM onboarding just do endpoint compliance checking

attribute entry for each interface IP address used for URL-
redirected Web services
copy 2015 Cisco andor its affiliates All rights reservedBRKSEC-2035 Cisco Public
bull Problem Statement Any change to interface IP addressing (network relocation vMotion network infrastructure changes etc) requires new certificates to be generated with SAN attributes updated for new IP addresses
ndash Time-consuming process
ndash New certificates signed by 3rd-party CAs can be expensive
ndash Disruption to application services after new cert loaded
bull Solution
ndash Interface Alias Optionally assign ISE node interface (eth1 eth2 eth3) a unique hostnameFQDN which can be resolved to its local IP address using DNS
ndash Each PSN tracks which interfaces are enabled for each service and dynamically substitutes IP variable for URL redirection to the PSNs local interface alias (hostname + domain)
bull Considerations
ndash Manual configuration process from CLI
ndash Requires DNS to be updates for each alias

FQDN in SAN
60
bull Problem Statement Every ISE node requires a unique certificate
ndash New certificates signed by 3rd-party CAs can be expensive
ndash Time-consuming process to generate new certs each time new node added
ndash Certificate SAN must include FQDN entry for other web services (Sponsor MDP etc)
ndash Some endpoints require each PSN cert to be trusted and will prompt user to accept
bull Solution Wildcard Certificates
ndash Allows multiple ISE nodes to share single certificate for WebEAP authentication
ndash No longer requires custom SAN with node FQDN or interface IP addresses
ndash Most seamless and improved end-user experience
bull Considerations
ndash Less secure than unique certificate per node greater care to safeguard private key
ndash Limit exposure and deploy ISE into subdomain eg isecompanycom

Key business driver for multi-interface support is traffic separation and assumption that traffic for one service that enters on interface X will return from the interfacenetwork path
bull Problem Statement
ndash Packets received on any ISE interface relies on CARS routing table to determine egress interface and next hop address
bull Solution
ndash Static routes for each endpoint subnet must be configured on each node using CLI to use the desired web service interface
ndash Source NAT to Web Portal interfaces and configure static route to NATrsquoed network
bull Considerations
ndash If NAT not used then depending on network size and addressing complexity may require hundreds of static routes to be configured very difficult to manage and maintain
ndash Dedicated interface for Anchor Controller use case should not be impacted since client IP is local (L2 adjacent) to dedicated ISE interface in DMZ

Connection Messages Explanation
Connection Failed
Please check the connection
parameters
A routing or firewall problem exists between the ISE located in the data center and the MDM located in either the
DMZ or Cloud The firewalls configuration should be checked to confirm HTTPS is allowed in this direction
Connection Failed
404 Not Found
The most likely cause of an HTML 404 error code is that an instance was configured when it was not required or
that the wrong instance has been configured
Connection Failed
403 Forbidden
The user account setup on the MDM server does not have the proper roles associated to it Validate that the
account being used by ISE is assigned the REST API MDM role
Connection Failed
401 UnauthorizedThe user name or password is not correct for the account being used by ISE
Connection Failed There is a
problem with the server
certificate or ISE Trust store
ISE does not trust the certificate presented by the MDM website This indicates the certificate was not imported to
the ISE certificate store or the certificate has expired since it was imported
The MDM Server details are
valid and the connectivity was
successful
The connection has successfully been tested The administrator should also verify the MDM AUTHZ dictionary
has been populated with attributes

Passive Reassessment
bull Bulk recheck against MDM server using configurable timer (polling interval)
bull If result of periodic recheck shows that a connected endpoint is no longer compliant ISE sends a CoA to terminate session
Survivability
bull CoA is NOT sent for devices granted access while MDM server unavailable
bull If device is granted a ldquofail openrdquo or other limited access state (for example URL-redirected to MDM) user can hit Continue button when MDM is back online to trigger CoA

copy 2015 Cisco andor its affiliates All rights reservedBRKSEC-2035 Cisco Public
bull Problem Statement Any change to interface IP addressing (network relocation vMotion network infrastructure changes etc) requires new certificates to be generated with SAN attributes updated for new IP addresses
ndash Time-consuming process
ndash New certificates signed by 3rd-party CAs can be expensive
ndash Disruption to application services after new cert loaded
bull Solution
ndash Interface Alias Optionally assign ISE node interface (eth1 eth2 eth3) a unique hostnameFQDN which can be resolved to its local IP address using DNS
ndash Each PSN tracks which interfaces are enabled for each service and dynamically substitutes IP variable for URL redirection to the PSNs local interface alias (hostname + domain)
bull Considerations

FQDN in SAN
60
bull Problem Statement Every ISE node requires a unique certificate
ndash New certificates signed by 3rd-party CAs can be expensive
ndash Time-consuming process to generate new certs each time new node added
ndash Certificate SAN must include FQDN entry for other web services (Sponsor MDP etc)
ndash Some endpoints require each PSN cert to be trusted and will prompt user to accept
bull Solution Wildcard Certificates
ndash Allows multiple ISE nodes to share single certificate for WebEAP authentication
ndash No longer requires custom SAN with node FQDN or interface IP addresses
ndash Most seamless and improved end-user experience
bull Considerations
ndash Less secure than unique certificate per node greater care to safeguard private key
ndash Limit exposure and deploy ISE into subdomain eg isecompanycom

Key business driver for multi-interface support is traffic separation and assumption that traffic for one service that enters on interface X will return from the interfacenetwork path
bull Problem Statement
ndash Packets received on any ISE interface relies on CARS routing table to determine egress interface and next hop address
bull Solution
ndash Static routes for each endpoint subnet must be configured on each node using CLI to use the desired web service interface
ndash Source NAT to Web Portal interfaces and configure static route to NATrsquoed network
bull Considerations
ndash If NAT not used then depending on network size and addressing complexity may require hundreds of static routes to be configured very difficult to manage and maintain
ndash Dedicated interface for Anchor Controller use case should not be impacted since client IP is local (L2 adjacent) to dedicated ISE interface in DMZ

Connection Messages Explanation
Connection Failed
Please check the connection
parameters
A routing or firewall problem exists between the ISE located in the data center and the MDM located in either the
DMZ or Cloud The firewalls configuration should be checked to confirm HTTPS is allowed in this direction
Connection Failed
404 Not Found
The most likely cause of an HTML 404 error code is that an instance was configured when it was not required or
that the wrong instance has been configured
Connection Failed
403 Forbidden
The user account setup on the MDM server does not have the proper roles associated to it Validate that the
account being used by ISE is assigned the REST API MDM role
Connection Failed
401 UnauthorizedThe user name or password is not correct for the account being used by ISE
Connection Failed There is a
problem with the server
certificate or ISE Trust store
ISE does not trust the certificate presented by the MDM website This indicates the certificate was not imported to
the ISE certificate store or the certificate has expired since it was imported
The MDM Server details are
valid and the connectivity was
successful
The connection has successfully been tested The administrator should also verify the MDM AUTHZ dictionary
has been populated with attributes

bull Scalability = 30 API calls per second ( gt100`000 callsh)Consider Internet bandwidth and latency for cloud-based solutions
Passive Reassessment
bull Bulk recheck against MDM server using configurable timer (polling interval)
bull If result of periodic recheck shows that a connected endpoint is no longer compliant ISE sends a CoA to terminate session
Survivability
bull CoA is NOT sent for devices granted access while MDM server unavailable
bull If device is granted a ldquofail openrdquo or other limited access state (for example URL-redirected to MDM) user can hit Continue button when MDM is back online to trigger CoA

WLC ndash URL Redirection ACL
bull Problem Statement To register iOS and Android devices for BYOD or MDM they may require Internet access for either downloading supplicant software or for device validation from highly dynamic sources like iTunes and Google Play Same applies for MDM marked non-compliant devices In contrast WLC URL redirection ACL only offers static IP-based rule definition
bull Workaround (works also with older WLC versions eg 741300)
a) Permit full Internet access denyredirect only internal IP address ranges
b) Permit access to Apple and Google IP ranges denyredirect other traffic
c) Fake DNS resolutionbull Optional Plus external DNS-based network access enforcement (ASA WSA or others)

attribute entry for each interface IP address used for URL-
redirected Web services
copy 2015 Cisco andor its affiliates All rights reservedBRKSEC-2035 Cisco Public
bull Problem Statement Any change to interface IP addressing (network relocation vMotion network infrastructure changes etc) requires new certificates to be generated with SAN attributes updated for new IP addresses
ndash Time-consuming process
ndash New certificates signed by 3rd-party CAs can be expensive
ndash Disruption to application services after new cert loaded
bull Solution
ndash Interface Alias Optionally assign ISE node interface (eth1 eth2 eth3) a unique hostnameFQDN which can be resolved to its local IP address using DNS
ndash Each PSN tracks which interfaces are enabled for each service and dynamically substitutes IP variable for URL redirection to the PSNs local interface alias (hostname + domain)
bull Considerations
ndash Manual configuration process from CLI

FQDN in SAN
60
bull Problem Statement Every ISE node requires a unique certificate
ndash New certificates signed by 3rd-party CAs can be expensive
ndash Time-consuming process to generate new certs each time new node added
ndash Certificate SAN must include FQDN entry for other web services (Sponsor MDP etc)
ndash Some endpoints require each PSN cert to be trusted and will prompt user to accept
bull Solution Wildcard Certificates
ndash Allows multiple ISE nodes to share single certificate for WebEAP authentication
ndash No longer requires custom SAN with node FQDN or interface IP addresses
ndash Most seamless and improved end-user experience
bull Considerations
ndash Less secure than unique certificate per node greater care to safeguard private key
ndash Limit exposure and deploy ISE into subdomain eg isecompanycom

Key business driver for multi-interface support is traffic separation and assumption that traffic for one service that enters on interface X will return from the interfacenetwork path
bull Problem Statement
ndash Packets received on any ISE interface relies on CARS routing table to determine egress interface and next hop address
bull Solution
ndash Static routes for each endpoint subnet must be configured on each node using CLI to use the desired web service interface
ndash Source NAT to Web Portal interfaces and configure static route to NATrsquoed network
bull Considerations
ndash If NAT not used then depending on network size and addressing complexity may require hundreds of static routes to be configured very difficult to manage and maintain
ndash Dedicated interface for Anchor Controller use case should not be impacted since client IP is local (L2 adjacent) to dedicated ISE interface in DMZ

Connection Messages Explanation
Connection Failed
Please check the connection
parameters
A routing or firewall problem exists between the ISE located in the data center and the MDM located in either the
DMZ or Cloud The firewalls configuration should be checked to confirm HTTPS is allowed in this direction
Connection Failed
404 Not Found
The most likely cause of an HTML 404 error code is that an instance was configured when it was not required or
that the wrong instance has been configured
Connection Failed
403 Forbidden
The user account setup on the MDM server does not have the proper roles associated to it Validate that the
account being used by ISE is assigned the REST API MDM role
Connection Failed
401 UnauthorizedThe user name or password is not correct for the account being used by ISE
Connection Failed There is a
problem with the server
certificate or ISE Trust store
ISE does not trust the certificate presented by the MDM website This indicates the certificate was not imported to
the ISE certificate store or the certificate has expired since it was imported
The MDM Server details are
valid and the connectivity was
successful
The connection has successfully been tested The administrator should also verify the MDM AUTHZ dictionary
has been populated with attributes

Passive Reassessment
bull Bulk recheck against MDM server using configurable timer (polling interval)
bull If result of periodic recheck shows that a connected endpoint is no longer compliant ISE sends a CoA to terminate session
Survivability
bull CoA is NOT sent for devices granted access while MDM server unavailable

copy 2015 Cisco andor its affiliates All rights reservedBRKSEC-2035 Cisco Public
bull Problem Statement Any change to interface IP addressing (network relocation vMotion network infrastructure changes etc) requires new certificates to be generated with SAN attributes updated for new IP addresses
ndash Time-consuming process
ndash New certificates signed by 3rd-party CAs can be expensive
ndash Disruption to application services after new cert loaded
bull Solution
ndash Interface Alias Optionally assign ISE node interface (eth1 eth2 eth3) a unique hostnameFQDN which can be resolved to its local IP address using DNS
ndash Each PSN tracks which interfaces are enabled for each service and dynamically substitutes IP variable for URL redirection to the PSNs local interface alias (hostname + domain)
bull Considerations
ndash Manual configuration process from CLI
ndash Requires DNS to be updates for each alias

FQDN in SAN
60
bull Problem Statement Every ISE node requires a unique certificate
ndash New certificates signed by 3rd-party CAs can be expensive
ndash Time-consuming process to generate new certs each time new node added
ndash Certificate SAN must include FQDN entry for other web services (Sponsor MDP etc)
ndash Some endpoints require each PSN cert to be trusted and will prompt user to accept
bull Solution Wildcard Certificates
ndash Allows multiple ISE nodes to share single certificate for WebEAP authentication
ndash No longer requires custom SAN with node FQDN or interface IP addresses
ndash Most seamless and improved end-user experience
bull Considerations
ndash Less secure than unique certificate per node greater care to safeguard private key
ndash Limit exposure and deploy ISE into subdomain eg isecompanycom

Key business driver for multi-interface support is traffic separation and assumption that traffic for one service that enters on interface X will return from the interfacenetwork path
bull Problem Statement
ndash Packets received on any ISE interface relies on CARS routing table to determine egress interface and next hop address
bull Solution
ndash Static routes for each endpoint subnet must be configured on each node using CLI to use the desired web service interface
ndash Source NAT to Web Portal interfaces and configure static route to NATrsquoed network
bull Considerations
ndash If NAT not used then depending on network size and addressing complexity may require hundreds of static routes to be configured very difficult to manage and maintain
ndash Dedicated interface for Anchor Controller use case should not be impacted since client IP is local (L2 adjacent) to dedicated ISE interface in DMZ

Connection Messages Explanation
Connection Failed
Please check the connection
parameters
A routing or firewall problem exists between the ISE located in the data center and the MDM located in either the
DMZ or Cloud The firewalls configuration should be checked to confirm HTTPS is allowed in this direction
Connection Failed
404 Not Found
The most likely cause of an HTML 404 error code is that an instance was configured when it was not required or
that the wrong instance has been configured
Connection Failed
403 Forbidden
The user account setup on the MDM server does not have the proper roles associated to it Validate that the
account being used by ISE is assigned the REST API MDM role
Connection Failed
401 UnauthorizedThe user name or password is not correct for the account being used by ISE
Connection Failed There is a
problem with the server
certificate or ISE Trust store
ISE does not trust the certificate presented by the MDM website This indicates the certificate was not imported to
the ISE certificate store or the certificate has expired since it was imported
The MDM Server details are
valid and the connectivity was
successful
The connection has successfully been tested The administrator should also verify the MDM AUTHZ dictionary
has been populated with attributes

bull ISE 13 or
bull ISE 12 Patch with latest patch (but min patch 6 is recommended)
ndash MDM cachingbull If device connects to network ISE caches the MDM state
bull Next time device attempts to log-on ISE use the cache to allow access per previous MDM check
bull Once the device is on the network ISE checks with MDM using API call if the MDM state has changed (eg compliant -gt non-compliant)
bull If the state has changed ISE issues a COA to give a new policy (as per updated MDM attributes)
bull A note to ISE 13 12 patches

attribute entry for each interface IP address used for URL-

copy 2015 Cisco andor its affiliates All rights reservedBRKSEC-2035 Cisco Public
bull Problem Statement Any change to interface IP addressing (network relocation vMotion network infrastructure changes etc) requires new certificates to be generated with SAN attributes updated for new IP addresses
ndash Time-consuming process
ndash New certificates signed by 3rd-party CAs can be expensive
ndash Disruption to application services after new cert loaded
bull Solution
ndash Interface Alias Optionally assign ISE node interface (eth1 eth2 eth3) a unique hostnameFQDN which can be resolved to its local IP address using DNS
ndash Each PSN tracks which interfaces are enabled for each service and dynamically substitutes IP variable for URL redirection to the PSNs local interface alias (hostname + domain)
bull Considerations
ndash Manual configuration process from CLI
ndash Requires DNS to be updates for each alias

FQDN in SAN
60
bull Problem Statement Every ISE node requires a unique certificate
ndash New certificates signed by 3rd-party CAs can be expensive
ndash Time-consuming process to generate new certs each time new node added
ndash Certificate SAN must include FQDN entry for other web services (Sponsor MDP etc)
ndash Some endpoints require each PSN cert to be trusted and will prompt user to accept
bull Solution Wildcard Certificates
ndash Allows multiple ISE nodes to share single certificate for WebEAP authentication
ndash No longer requires custom SAN with node FQDN or interface IP addresses
ndash Most seamless and improved end-user experience
bull Considerations
ndash Less secure than unique certificate per node greater care to safeguard private key
ndash Limit exposure and deploy ISE into subdomain eg isecompanycom

Key business driver for multi-interface support is traffic separation and assumption that traffic for one service that enters on interface X will return from the interfacenetwork path
bull Problem Statement
ndash Packets received on any ISE interface relies on CARS routing table to determine egress interface and next hop address
bull Solution
ndash Static routes for each endpoint subnet must be configured on each node using CLI to use the desired web service interface
ndash Source NAT to Web Portal interfaces and configure static route to NATrsquoed network
bull Considerations
ndash If NAT not used then depending on network size and addressing complexity may require hundreds of static routes to be configured very difficult to manage and maintain
ndash Dedicated interface for Anchor Controller use case should not be impacted since client IP is local (L2 adjacent) to dedicated ISE interface in DMZ

Connection Messages Explanation
Connection Failed
Please check the connection
parameters
A routing or firewall problem exists between the ISE located in the data center and the MDM located in either the
DMZ or Cloud The firewalls configuration should be checked to confirm HTTPS is allowed in this direction
Connection Failed
404 Not Found
The most likely cause of an HTML 404 error code is that an instance was configured when it was not required or
that the wrong instance has been configured
Connection Failed
403 Forbidden
The user account setup on the MDM server does not have the proper roles associated to it Validate that the
account being used by ISE is assigned the REST API MDM role
Connection Failed
401 UnauthorizedThe user name or password is not correct for the account being used by ISE
Connection Failed There is a
problem with the server
certificate or ISE Trust store
ISE does not trust the certificate presented by the MDM website This indicates the certificate was not imported to
the ISE certificate store or the certificate has expired since it was imported
The MDM Server details are
valid and the connectivity was
successful
The connection has successfully been tested The administrator should also verify the MDM AUTHZ dictionary
has been populated with attributes

Passive Reassessment
bull Bulk recheck against MDM server using configurable timer (polling interval)
bull If result of periodic recheck shows that a connected endpoint is no longer compliant ISE sends a CoA to terminate session
Survivability
bull CoA is NOT sent for devices granted access while MDM server unavailable

attribute entry for each interface IP address used for URL-
redirected Web services
copy 2015 Cisco andor its affiliates All rights reservedBRKSEC-2035 Cisco Public
bull Problem Statement Any change to interface IP addressing (network relocation vMotion network infrastructure changes etc) requires new certificates to be generated with SAN attributes updated for new IP addresses
ndash Time-consuming process
ndash New certificates signed by 3rd-party CAs can be expensive
ndash Disruption to application services after new cert loaded
bull Solution
ndash Interface Alias Optionally assign ISE node interface (eth1 eth2 eth3) a unique hostnameFQDN which can be resolved to its local IP address using DNS
ndash Each PSN tracks which interfaces are enabled for each service and dynamically substitutes IP variable for URL redirection to the PSNs local interface alias (hostname + domain)
bull Considerations
ndash Manual configuration process from CLI
ndash Requires DNS to be updates for each alias

FQDN in SAN
60
bull Problem Statement Every ISE node requires a unique certificate
ndash New certificates signed by 3rd-party CAs can be expensive
ndash Time-consuming process to generate new certs each time new node added
ndash Certificate SAN must include FQDN entry for other web services (Sponsor MDP etc)
ndash Some endpoints require each PSN cert to be trusted and will prompt user to accept
bull Solution Wildcard Certificates
ndash Allows multiple ISE nodes to share single certificate for WebEAP authentication
ndash No longer requires custom SAN with node FQDN or interface IP addresses
ndash Most seamless and improved end-user experience
bull Considerations
ndash Less secure than unique certificate per node greater care to safeguard private key
ndash Limit exposure and deploy ISE into subdomain eg isecompanycom

Key business driver for multi-interface support is traffic separation and assumption that traffic for one service that enters on interface X will return from the interfacenetwork path
bull Problem Statement
ndash Packets received on any ISE interface relies on CARS routing table to determine egress interface and next hop address
bull Solution
ndash Static routes for each endpoint subnet must be configured on each node using CLI to use the desired web service interface
ndash Source NAT to Web Portal interfaces and configure static route to NATrsquoed network
bull Considerations
ndash If NAT not used then depending on network size and addressing complexity may require hundreds of static routes to be configured very difficult to manage and maintain
ndash Dedicated interface for Anchor Controller use case should not be impacted since client IP is local (L2 adjacent) to dedicated ISE interface in DMZ

Connection Messages Explanation
Connection Failed
Please check the connection
parameters
A routing or firewall problem exists between the ISE located in the data center and the MDM located in either the
DMZ or Cloud The firewalls configuration should be checked to confirm HTTPS is allowed in this direction
Connection Failed
404 Not Found
The most likely cause of an HTML 404 error code is that an instance was configured when it was not required or
that the wrong instance has been configured
Connection Failed
403 Forbidden
The user account setup on the MDM server does not have the proper roles associated to it Validate that the
account being used by ISE is assigned the REST API MDM role
Connection Failed
401 UnauthorizedThe user name or password is not correct for the account being used by ISE
Connection Failed There is a
problem with the server
certificate or ISE Trust store
ISE does not trust the certificate presented by the MDM website This indicates the certificate was not imported to
the ISE certificate store or the certificate has expired since it was imported
The MDM Server details are
valid and the connectivity was
successful
The connection has successfully been tested The administrator should also verify the MDM AUTHZ dictionary
has been populated with attributes

ISE ndash MDM IntegrationScalability
bull Scalability = 30 API calls per second ( gt100`000 callsh)Consider Internet bandwidth and latency for cloud-based solutions
Passive Reassessment
bull Bulk recheck against MDM server using configurable timer (polling interval)
bull If result of periodic recheck shows that a connected endpoint is no longer compliant ISE sends a CoA to terminate session
Survivability
bull CoA is NOT sent for devices granted access while MDM server unavailable
bull If device is granted a ldquofail openrdquo or other limited access state (for example URL-redirected to MDM) user can hit Continue button when MDM is back online to trigger CoA

copy 2015 Cisco andor its affiliates All rights reservedBRKSEC-2035 Cisco Public
bull Problem Statement Any change to interface IP addressing (network relocation vMotion network infrastructure changes etc) requires new certificates to be generated with SAN attributes updated for new IP addresses
ndash Time-consuming process
ndash New certificates signed by 3rd-party CAs can be expensive
ndash Disruption to application services after new cert loaded
bull Solution
ndash Interface Alias Optionally assign ISE node interface (eth1 eth2 eth3) a unique hostnameFQDN which can be resolved to its local IP address using DNS
ndash Each PSN tracks which interfaces are enabled for each service and dynamically substitutes IP variable for URL redirection to the PSNs local interface alias (hostname + domain)
bull Considerations
ndash Manual configuration process from CLI

FQDN in SAN
60
bull Problem Statement Every ISE node requires a unique certificate
ndash New certificates signed by 3rd-party CAs can be expensive
ndash Time-consuming process to generate new certs each time new node added
ndash Certificate SAN must include FQDN entry for other web services (Sponsor MDP etc)
ndash Some endpoints require each PSN cert to be trusted and will prompt user to accept
bull Solution Wildcard Certificates
ndash Allows multiple ISE nodes to share single certificate for WebEAP authentication
ndash No longer requires custom SAN with node FQDN or interface IP addresses
ndash Most seamless and improved end-user experience
bull Considerations
ndash Less secure than unique certificate per node greater care to safeguard private key
ndash Limit exposure and deploy ISE into subdomain eg isecompanycom

Key business driver for multi-interface support is traffic separation and assumption that traffic for one service that enters on interface X will return from the interfacenetwork path
bull Problem Statement
ndash Packets received on any ISE interface relies on CARS routing table to determine egress interface and next hop address
bull Solution
ndash Static routes for each endpoint subnet must be configured on each node using CLI to use the desired web service interface
ndash Source NAT to Web Portal interfaces and configure static route to NATrsquoed network
bull Considerations
ndash If NAT not used then depending on network size and addressing complexity may require hundreds of static routes to be configured very difficult to manage and maintain
ndash Dedicated interface for Anchor Controller use case should not be impacted since client IP is local (L2 adjacent) to dedicated ISE interface in DMZ

Connection Messages Explanation
Connection Failed
Please check the connection
parameters
A routing or firewall problem exists between the ISE located in the data center and the MDM located in either the
DMZ or Cloud The firewalls configuration should be checked to confirm HTTPS is allowed in this direction
Connection Failed
404 Not Found
The most likely cause of an HTML 404 error code is that an instance was configured when it was not required or
that the wrong instance has been configured
Connection Failed
403 Forbidden
The user account setup on the MDM server does not have the proper roles associated to it Validate that the
account being used by ISE is assigned the REST API MDM role
Connection Failed
401 UnauthorizedThe user name or password is not correct for the account being used by ISE
Connection Failed There is a
problem with the server
certificate or ISE Trust store
ISE does not trust the certificate presented by the MDM website This indicates the certificate was not imported to
the ISE certificate store or the certificate has expired since it was imported
The MDM Server details are
valid and the connectivity was
successful
The connection has successfully been tested The administrator should also verify the MDM AUTHZ dictionary
has been populated with attributes

Passive Reassessment
bull Bulk recheck against MDM server using configurable timer (polling interval)
bull If result of periodic recheck shows that a connected endpoint is no longer compliant ISE sends a CoA to terminate session
Survivability
bull CoA is NOT sent for devices granted access while MDM server unavailable
bull If device is granted a ldquofail openrdquo or other limited access state (for example URL-redirected to MDM) user can hit Continue button when MDM is back online to trigger CoA

copy 2015 Cisco andor its affiliates All rights reservedBRKSEC-2035 Cisco Public
bull Problem Statement Any change to interface IP addressing (network relocation vMotion network infrastructure changes etc) requires new certificates to be generated with SAN attributes updated for new IP addresses
ndash Time-consuming process
ndash New certificates signed by 3rd-party CAs can be expensive
ndash Disruption to application services after new cert loaded
bull Solution
ndash Interface Alias Optionally assign ISE node interface (eth1 eth2 eth3) a unique hostnameFQDN which can be resolved to its local IP address using DNS
ndash Each PSN tracks which interfaces are enabled for each service and dynamically substitutes IP variable for URL redirection to the PSNs local interface alias (hostname + domain)

FQDN in SAN
60
bull Problem Statement Every ISE node requires a unique certificate
ndash New certificates signed by 3rd-party CAs can be expensive
ndash Time-consuming process to generate new certs each time new node added
ndash Certificate SAN must include FQDN entry for other web services (Sponsor MDP etc)
ndash Some endpoints require each PSN cert to be trusted and will prompt user to accept
bull Solution Wildcard Certificates
ndash Allows multiple ISE nodes to share single certificate for WebEAP authentication
ndash No longer requires custom SAN with node FQDN or interface IP addresses
ndash Most seamless and improved end-user experience
bull Considerations
ndash Less secure than unique certificate per node greater care to safeguard private key
ndash Limit exposure and deploy ISE into subdomain eg isecompanycom

Key business driver for multi-interface support is traffic separation and assumption that traffic for one service that enters on interface X will return from the interfacenetwork path
bull Problem Statement
ndash Packets received on any ISE interface relies on CARS routing table to determine egress interface and next hop address
bull Solution
ndash Static routes for each endpoint subnet must be configured on each node using CLI to use the desired web service interface
ndash Source NAT to Web Portal interfaces and configure static route to NATrsquoed network
bull Considerations
ndash If NAT not used then depending on network size and addressing complexity may require hundreds of static routes to be configured very difficult to manage and maintain
ndash Dedicated interface for Anchor Controller use case should not be impacted since client IP is local (L2 adjacent) to dedicated ISE interface in DMZ

ISE ndash MDM configuration most common issues
Connection Messages Explanation
Connection Failed
Please check the connection
parameters
A routing or firewall problem exists between the ISE located in the data center and the MDM located in either the
DMZ or Cloud The firewalls configuration should be checked to confirm HTTPS is allowed in this direction
Connection Failed
404 Not Found
The most likely cause of an HTML 404 error code is that an instance was configured when it was not required or
that the wrong instance has been configured
Connection Failed
403 Forbidden
The user account setup on the MDM server does not have the proper roles associated to it Validate that the
account being used by ISE is assigned the REST API MDM role
Connection Failed
401 UnauthorizedThe user name or password is not correct for the account being used by ISE
Connection Failed There is a
problem with the server
certificate or ISE Trust store
ISE does not trust the certificate presented by the MDM website This indicates the certificate was not imported to
the ISE certificate store or the certificate has expired since it was imported
The MDM Server details are
valid and the connectivity was
successful
The connection has successfully been tested The administrator should also verify the MDM AUTHZ dictionary
has been populated with attributes

ISE ndash MDM IntegrationScalability
bull Scalability = 30 API calls per second ( gt100`000 callsh)Consider Internet bandwidth and latency for cloud-based solutions
Passive Reassessment
bull Bulk recheck against MDM server using configurable timer (polling interval)
bull If result of periodic recheck shows that a connected endpoint is no longer compliant ISE sends a CoA to terminate session
Survivability
bull CoA is NOT sent for devices granted access while MDM server unavailable
bull If device is granted a ldquofail openrdquo or other limited access state (for example URL-redirected to MDM) user can hit Continue button when MDM is back online to trigger CoA

attribute entry for each interface IP address used for URL-
redirected Web services
copy 2015 Cisco andor its affiliates All rights reservedBRKSEC-2035 Cisco Public
bull Problem Statement Any change to interface IP addressing (network relocation vMotion network infrastructure changes etc) requires new certificates to be generated with SAN attributes updated for new IP addresses
ndash Time-consuming process
ndash New certificates signed by 3rd-party CAs can be expensive
ndash Disruption to application services after new cert loaded
bull Solution
ndash Interface Alias Optionally assign ISE node interface (eth1 eth2 eth3) a unique hostnameFQDN which can be resolved to its local IP address using DNS
ndash Each PSN tracks which interfaces are enabled for each service and dynamically substitutes IP variable for URL redirection to the PSNs local interface alias (hostname + domain)
bull Considerations
ndash Manual configuration process from CLI
ndash Requires DNS to be updates for each alias

FQDN in SAN
60
bull Problem Statement Every ISE node requires a unique certificate
ndash New certificates signed by 3rd-party CAs can be expensive
ndash Time-consuming process to generate new certs each time new node added
ndash Certificate SAN must include FQDN entry for other web services (Sponsor MDP etc)
ndash Some endpoints require each PSN cert to be trusted and will prompt user to accept
bull Solution Wildcard Certificates
ndash Allows multiple ISE nodes to share single certificate for WebEAP authentication
ndash No longer requires custom SAN with node FQDN or interface IP addresses
ndash Most seamless and improved end-user experience
bull Considerations
ndash Less secure than unique certificate per node greater care to safeguard private key
ndash Limit exposure and deploy ISE into subdomain eg isecompanycom

Key business driver for multi-interface support is traffic separation and assumption that traffic for one service that enters on interface X will return from the interfacenetwork path
bull Problem Statement
ndash Packets received on any ISE interface relies on CARS routing table to determine egress interface and next hop address
bull Solution
ndash Static routes for each endpoint subnet must be configured on each node using CLI to use the desired web service interface
ndash Source NAT to Web Portal interfaces and configure static route to NATrsquoed network
bull Considerations
ndash If NAT not used then depending on network size and addressing complexity may require hundreds of static routes to be configured very difficult to manage and maintain
ndash Dedicated interface for Anchor Controller use case should not be impacted since client IP is local (L2 adjacent) to dedicated ISE interface in DMZ

Connection Messages Explanation
Connection Failed
Please check the connection
parameters
A routing or firewall problem exists between the ISE located in the data center and the MDM located in either the
DMZ or Cloud The firewalls configuration should be checked to confirm HTTPS is allowed in this direction
Connection Failed
404 Not Found
The most likely cause of an HTML 404 error code is that an instance was configured when it was not required or
that the wrong instance has been configured
Connection Failed
403 Forbidden
The user account setup on the MDM server does not have the proper roles associated to it Validate that the
account being used by ISE is assigned the REST API MDM role
Connection Failed
401 UnauthorizedThe user name or password is not correct for the account being used by ISE
Connection Failed There is a
problem with the server
certificate or ISE Trust store
ISE does not trust the certificate presented by the MDM website This indicates the certificate was not imported to
the ISE certificate store or the certificate has expired since it was imported
The MDM Server details are
valid and the connectivity was
successful
The connection has successfully been tested The administrator should also verify the MDM AUTHZ dictionary
has been populated with attributes

Passive Reassessment
bull Bulk recheck against MDM server using configurable timer (polling interval)
bull If result of periodic recheck shows that a connected endpoint is no longer compliant ISE sends a CoA to terminate session
Survivability
bull CoA is NOT sent for devices granted access while MDM server unavailable
bull If device is granted a ldquofail openrdquo or other limited access state (for example URL-redirected to MDM) user can hit Continue button when MDM is back online to trigger CoA

copy 2015 Cisco andor its affiliates All rights reservedBRKSEC-2035 Cisco Public
bull Problem Statement Any change to interface IP addressing (network relocation vMotion network infrastructure changes etc) requires new certificates to be generated with SAN attributes updated for new IP addresses
ndash Time-consuming process
ndash New certificates signed by 3rd-party CAs can be expensive
ndash Disruption to application services after new cert loaded
bull Solution
ndash Interface Alias Optionally assign ISE node interface (eth1 eth2 eth3) a unique hostnameFQDN which can be resolved to its local IP address using DNS
ndash Each PSN tracks which interfaces are enabled for each service and dynamically substitutes IP variable for URL redirection to the PSNs local interface alias (hostname + domain)

FQDN in SAN
60
bull Problem Statement Every ISE node requires a unique certificate
ndash New certificates signed by 3rd-party CAs can be expensive
ndash Time-consuming process to generate new certs each time new node added
ndash Certificate SAN must include FQDN entry for other web services (Sponsor MDP etc)
ndash Some endpoints require each PSN cert to be trusted and will prompt user to accept
bull Solution Wildcard Certificates
ndash Allows multiple ISE nodes to share single certificate for WebEAP authentication
ndash No longer requires custom SAN with node FQDN or interface IP addresses
ndash Most seamless and improved end-user experience
bull Considerations
ndash Less secure than unique certificate per node greater care to safeguard private key
ndash Limit exposure and deploy ISE into subdomain eg isecompanycom

Key business driver for multi-interface support is traffic separation and assumption that traffic for one service that enters on interface X will return from the interfacenetwork path
bull Problem Statement
ndash Packets received on any ISE interface relies on CARS routing table to determine egress interface and next hop address
bull Solution
ndash Static routes for each endpoint subnet must be configured on each node using CLI to use the desired web service interface
ndash Source NAT to Web Portal interfaces and configure static route to NATrsquoed network
bull Considerations
ndash If NAT not used then depending on network size and addressing complexity may require hundreds of static routes to be configured very difficult to manage and maintain
ndash Dedicated interface for Anchor Controller use case should not be impacted since client IP is local (L2 adjacent) to dedicated ISE interface in DMZ

Connection Messages Explanation
Connection Failed
Please check the connection
parameters
A routing or firewall problem exists between the ISE located in the data center and the MDM located in either the
DMZ or Cloud The firewalls configuration should be checked to confirm HTTPS is allowed in this direction
Connection Failed
404 Not Found
The most likely cause of an HTML 404 error code is that an instance was configured when it was not required or
that the wrong instance has been configured
Connection Failed
403 Forbidden
The user account setup on the MDM server does not have the proper roles associated to it Validate that the
account being used by ISE is assigned the REST API MDM role
Connection Failed
401 UnauthorizedThe user name or password is not correct for the account being used by ISE
Connection Failed There is a
problem with the server
certificate or ISE Trust store
ISE does not trust the certificate presented by the MDM website This indicates the certificate was not imported to
the ISE certificate store or the certificate has expired since it was imported
The MDM Server details are
valid and the connectivity was
successful
The connection has successfully been tested The administrator should also verify the MDM AUTHZ dictionary
has been populated with attributes

Passive Reassessment
bull Bulk recheck against MDM server using configurable timer (polling interval)
bull If result of periodic recheck shows that a connected endpoint is no longer compliant ISE sends a CoA to terminate session
Survivability
bull CoA is NOT sent for devices granted access while MDM server unavailable
bull If device is granted a ldquofail openrdquo or other limited access state (for example URL-redirected to MDM) user can hit Continue button when MDM is back online to trigger CoA

attribute entry for each interface IP address used for URL-
redirected Web services
copy 2015 Cisco andor its affiliates All rights reservedBRKSEC-2035 Cisco Public
bull Problem Statement Any change to interface IP addressing (network relocation vMotion network infrastructure changes etc) requires new certificates to be generated with SAN attributes updated for new IP addresses
ndash Time-consuming process
ndash New certificates signed by 3rd-party CAs can be expensive
ndash Disruption to application services after new cert loaded
bull Solution
ndash Interface Alias Optionally assign ISE node interface (eth1 eth2 eth3) a unique hostnameFQDN which can be resolved to its local IP address using DNS
ndash Each PSN tracks which interfaces are enabled for each service and dynamically substitutes IP variable for URL redirection to the PSNs local interface alias (hostname + domain)
bull Considerations

FQDN in SAN
60
bull Problem Statement Every ISE node requires a unique certificate
ndash New certificates signed by 3rd-party CAs can be expensive
ndash Time-consuming process to generate new certs each time new node added
ndash Certificate SAN must include FQDN entry for other web services (Sponsor MDP etc)
ndash Some endpoints require each PSN cert to be trusted and will prompt user to accept
bull Solution Wildcard Certificates
ndash Allows multiple ISE nodes to share single certificate for WebEAP authentication
ndash No longer requires custom SAN with node FQDN or interface IP addresses
ndash Most seamless and improved end-user experience
bull Considerations
ndash Less secure than unique certificate per node greater care to safeguard private key
ndash Limit exposure and deploy ISE into subdomain eg isecompanycom

Key business driver for multi-interface support is traffic separation and assumption that traffic for one service that enters on interface X will return from the interfacenetwork path
bull Problem Statement
ndash Packets received on any ISE interface relies on CARS routing table to determine egress interface and next hop address
bull Solution
ndash Static routes for each endpoint subnet must be configured on each node using CLI to use the desired web service interface
ndash Source NAT to Web Portal interfaces and configure static route to NATrsquoed network
bull Considerations
ndash If NAT not used then depending on network size and addressing complexity may require hundreds of static routes to be configured very difficult to manage and maintain
ndash Dedicated interface for Anchor Controller use case should not be impacted since client IP is local (L2 adjacent) to dedicated ISE interface in DMZ

Connection Messages Explanation
Connection Failed
Please check the connection
parameters
A routing or firewall problem exists between the ISE located in the data center and the MDM located in either the
DMZ or Cloud The firewalls configuration should be checked to confirm HTTPS is allowed in this direction
Connection Failed
404 Not Found
The most likely cause of an HTML 404 error code is that an instance was configured when it was not required or
that the wrong instance has been configured
Connection Failed
403 Forbidden
The user account setup on the MDM server does not have the proper roles associated to it Validate that the
account being used by ISE is assigned the REST API MDM role
Connection Failed
401 UnauthorizedThe user name or password is not correct for the account being used by ISE
Connection Failed There is a
problem with the server
certificate or ISE Trust store
ISE does not trust the certificate presented by the MDM website This indicates the certificate was not imported to
the ISE certificate store or the certificate has expired since it was imported
The MDM Server details are
valid and the connectivity was
successful
The connection has successfully been tested The administrator should also verify the MDM AUTHZ dictionary
has been populated with attributes

attribute entry for each interface IP address used for URL-
redirected Web services
copy 2015 Cisco andor its affiliates All rights reservedBRKSEC-2035 Cisco Public
bull Problem Statement Any change to interface IP addressing (network relocation vMotion network infrastructure changes etc) requires new certificates to be generated with SAN attributes updated for new IP addresses
ndash Time-consuming process
ndash New certificates signed by 3rd-party CAs can be expensive
ndash Disruption to application services after new cert loaded
bull Solution
ndash Interface Alias Optionally assign ISE node interface (eth1 eth2 eth3) a unique hostnameFQDN which can be resolved to its local IP address using DNS
ndash Each PSN tracks which interfaces are enabled for each service and dynamically substitutes IP variable for URL redirection to the PSNs local interface alias (hostname + domain)
bull Considerations

bull Problem Statement Every ISE node requires a unique certificate
ndash New certificates signed by 3rd-party CAs can be expensive
ndash Time-consuming process to generate new certs each time new node added
ndash Certificate SAN must include FQDN entry for other web services (Sponsor MDP etc)
ndash Some endpoints require each PSN cert to be trusted and will prompt user to accept
bull Solution Wildcard Certificates
ndash Allows multiple ISE nodes to share single certificate for WebEAP authentication
ndash No longer requires custom SAN with node FQDN or interface IP addresses
ndash Most seamless and improved end-user experience
bull Considerations
ndash Less secure than unique certificate per node greater care to safeguard private key
ndash Limit exposure and deploy ISE into subdomain eg isecompanycom

Key business driver for multi-interface support is traffic separation and assumption that traffic for one service that enters on interface X will return from the interfacenetwork path
bull Problem Statement
ndash Packets received on any ISE interface relies on CARS routing table to determine egress interface and next hop address
bull Solution
ndash Static routes for each endpoint subnet must be configured on each node using CLI to use the desired web service interface
ndash Source NAT to Web Portal interfaces and configure static route to NATrsquoed network
bull Considerations
ndash If NAT not used then depending on network size and addressing complexity may require hundreds of static routes to be configured very difficult to manage and maintain
ndash Dedicated interface for Anchor Controller use case should not be impacted since client IP is local (L2 adjacent) to dedicated ISE interface in DMZ

Connection Messages Explanation
Connection Failed
Please check the connection
parameters
A routing or firewall problem exists between the ISE located in the data center and the MDM located in either the
DMZ or Cloud The firewalls configuration should be checked to confirm HTTPS is allowed in this direction
Connection Failed
404 Not Found
The most likely cause of an HTML 404 error code is that an instance was configured when it was not required or
that the wrong instance has been configured
Connection Failed
403 Forbidden
The user account setup on the MDM server does not have the proper roles associated to it Validate that the
account being used by ISE is assigned the REST API MDM role
Connection Failed
401 UnauthorizedThe user name or password is not correct for the account being used by ISE
Connection Failed There is a
problem with the server
certificate or ISE Trust store
ISE does not trust the certificate presented by the MDM website This indicates the certificate was not imported to
the ISE certificate store or the certificate has expired since it was imported
The MDM Server details are
valid and the connectivity was
successful
The connection has successfully been tested The administrator should also verify the MDM AUTHZ dictionary
has been populated with attributes

Passive Reassessment
bull Bulk recheck against MDM server using configurable timer (polling interval)
bull If result of periodic recheck shows that a connected endpoint is no longer compliant ISE sends a CoA to terminate session
Survivability
bull CoA is NOT sent for devices granted access while MDM server unavailable
bull If device is granted a ldquofail openrdquo or other limited access state (for example URL-redirected to MDM) user can hit Continue button when MDM is back online to trigger CoA

attribute entry for each interface IP address used for URL-
redirected Web services
copy 2015 Cisco andor its affiliates All rights reservedBRKSEC-2035 Cisco Public
bull Problem Statement Any change to interface IP addressing (network relocation vMotion network infrastructure changes etc) requires new certificates to be generated with SAN attributes updated for new IP addresses
ndash Time-consuming process
ndash New certificates signed by 3rd-party CAs can be expensive
ndash Disruption to application services after new cert loaded
bull Solution
ndash Interface Alias Optionally assign ISE node interface (eth1 eth2 eth3) a unique hostnameFQDN which can be resolved to its local IP address using DNS
ndash Each PSN tracks which interfaces are enabled for each service and dynamically substitutes IP variable for URL redirection to the PSNs local interface alias (hostname + domain)
bull Considerations
ndash Manual configuration process from CLI

FQDN in SAN
60
bull Problem Statement Every ISE node requires a unique certificate
ndash New certificates signed by 3rd-party CAs can be expensive
ndash Time-consuming process to generate new certs each time new node added
ndash Certificate SAN must include FQDN entry for other web services (Sponsor MDP etc)
ndash Some endpoints require each PSN cert to be trusted and will prompt user to accept
bull Solution Wildcard Certificates
ndash Allows multiple ISE nodes to share single certificate for WebEAP authentication
ndash No longer requires custom SAN with node FQDN or interface IP addresses
ndash Most seamless and improved end-user experience
bull Considerations
ndash Less secure than unique certificate per node greater care to safeguard private key
ndash Limit exposure and deploy ISE into subdomain eg isecompanycom

Key business driver for multi-interface support is traffic separation and assumption that traffic for one service that enters on interface X will return from the interfacenetwork path
bull Problem Statement
ndash Packets received on any ISE interface relies on CARS routing table to determine egress interface and next hop address
bull Solution
ndash Static routes for each endpoint subnet must be configured on each node using CLI to use the desired web service interface
ndash Source NAT to Web Portal interfaces and configure static route to NATrsquoed network
bull Considerations
ndash If NAT not used then depending on network size and addressing complexity may require hundreds of static routes to be configured very difficult to manage and maintain
ndash Dedicated interface for Anchor Controller use case should not be impacted since client IP is local (L2 adjacent) to dedicated ISE interface in DMZ

Connection Messages Explanation
Connection Failed
Please check the connection
parameters
A routing or firewall problem exists between the ISE located in the data center and the MDM located in either the
DMZ or Cloud The firewalls configuration should be checked to confirm HTTPS is allowed in this direction
Connection Failed
404 Not Found
The most likely cause of an HTML 404 error code is that an instance was configured when it was not required or
that the wrong instance has been configured
Connection Failed
403 Forbidden
The user account setup on the MDM server does not have the proper roles associated to it Validate that the
account being used by ISE is assigned the REST API MDM role
Connection Failed
401 UnauthorizedThe user name or password is not correct for the account being used by ISE
Connection Failed There is a
problem with the server
certificate or ISE Trust store
ISE does not trust the certificate presented by the MDM website This indicates the certificate was not imported to
the ISE certificate store or the certificate has expired since it was imported
The MDM Server details are
valid and the connectivity was
successful
The connection has successfully been tested The administrator should also verify the MDM AUTHZ dictionary
has been populated with attributes

Passive Reassessment
bull Bulk recheck against MDM server using configurable timer (polling interval)
bull If result of periodic recheck shows that a connected endpoint is no longer compliant ISE sends a CoA to terminate session
Survivability
bull CoA is NOT sent for devices granted access while MDM server unavailable
bull If device is granted a ldquofail openrdquo or other limited access state (for example URL-redirected to MDM) user can hit Continue button when MDM is back online to trigger CoA

ndash New certificates signed by 3rd-party CAs can be expensive
ndash Disruption to application services after new cert loaded
bull Solution
ndash Interface Alias Optionally assign ISE node interface (eth1 eth2 eth3) a unique hostnameFQDN which can be resolved to its local IP address using DNS
ndash Each PSN tracks which interfaces are enabled for each service and dynamically substitutes IP variable for URL redirection to the PSNs local interface alias (hostname + domain)
bull Considerations
ndash Manual configuration process from CLI
ndash Requires DNS to be updates for each alias

bull Problem Statement Every ISE node requires a unique certificate
ndash New certificates signed by 3rd-party CAs can be expensive
ndash Time-consuming process to generate new certs each time new node added
ndash Certificate SAN must include FQDN entry for other web services (Sponsor MDP etc)
ndash Some endpoints require each PSN cert to be trusted and will prompt user to accept
bull Solution Wildcard Certificates
ndash Allows multiple ISE nodes to share single certificate for WebEAP authentication
ndash No longer requires custom SAN with node FQDN or interface IP addresses
ndash Most seamless and improved end-user experience
bull Considerations
ndash Less secure than unique certificate per node greater care to safeguard private key
ndash Limit exposure and deploy ISE into subdomain eg isecompanycom

Key business driver for multi-interface support is traffic separation and assumption that traffic for one service that enters on interface X will return from the interfacenetwork path
bull Problem Statement
ndash Packets received on any ISE interface relies on CARS routing table to determine egress interface and next hop address
bull Solution
ndash Static routes for each endpoint subnet must be configured on each node using CLI to use the desired web service interface
ndash Source NAT to Web Portal interfaces and configure static route to NATrsquoed network
bull Considerations
ndash If NAT not used then depending on network size and addressing complexity may require hundreds of static routes to be configured very difficult to manage and maintain
ndash Dedicated interface for Anchor Controller use case should not be impacted since client IP is local (L2 adjacent) to dedicated ISE interface in DMZ

Connection Messages Explanation
Connection Failed
Please check the connection
parameters
A routing or firewall problem exists between the ISE located in the data center and the MDM located in either the
DMZ or Cloud The firewalls configuration should be checked to confirm HTTPS is allowed in this direction
Connection Failed
404 Not Found
The most likely cause of an HTML 404 error code is that an instance was configured when it was not required or
that the wrong instance has been configured
Connection Failed
403 Forbidden
The user account setup on the MDM server does not have the proper roles associated to it Validate that the
account being used by ISE is assigned the REST API MDM role
Connection Failed
401 UnauthorizedThe user name or password is not correct for the account being used by ISE
Connection Failed There is a
problem with the server
certificate or ISE Trust store
ISE does not trust the certificate presented by the MDM website This indicates the certificate was not imported to
the ISE certificate store or the certificate has expired since it was imported
The MDM Server details are
valid and the connectivity was
successful
The connection has successfully been tested The administrator should also verify the MDM AUTHZ dictionary
has been populated with attributes

Passive Reassessment
bull Bulk recheck against MDM server using configurable timer (polling interval)
bull If result of periodic recheck shows that a connected endpoint is no longer compliant ISE sends a CoA to terminate session
Survivability
bull CoA is NOT sent for devices granted access while MDM server unavailable
bull If device is granted a ldquofail openrdquo or other limited access state (for example URL-redirected to MDM) user can hit Continue button when MDM is back online to trigger CoA

copy 2015 Cisco andor its affiliates All rights reservedBRKSEC-2035 Cisco Public
bull Problem Statement Any change to interface IP addressing (network relocation vMotion network infrastructure changes etc) requires new certificates to be generated with SAN attributes updated for new IP addresses
ndash Time-consuming process
ndash New certificates signed by 3rd-party CAs can be expensive
ndash Disruption to application services after new cert loaded
bull Solution
ndash Interface Alias Optionally assign ISE node interface (eth1 eth2 eth3) a unique hostnameFQDN which can be resolved to its local IP address using DNS
ndash Each PSN tracks which interfaces are enabled for each service and dynamically substitutes IP variable for URL redirection to the PSNs local interface alias (hostname + domain)
bull Considerations
ndash Manual configuration process from CLI
ndash Requires DNS to be updates for each alias

bull Problem Statement Every ISE node requires a unique certificate
ndash New certificates signed by 3rd-party CAs can be expensive
ndash Time-consuming process to generate new certs each time new node added
ndash Certificate SAN must include FQDN entry for other web services (Sponsor MDP etc)
ndash Some endpoints require each PSN cert to be trusted and will prompt user to accept
bull Solution Wildcard Certificates
ndash Allows multiple ISE nodes to share single certificate for WebEAP authentication
ndash No longer requires custom SAN with node FQDN or interface IP addresses
ndash Most seamless and improved end-user experience
bull Considerations
ndash Less secure than unique certificate per node greater care to safeguard private key
ndash Limit exposure and deploy ISE into subdomain eg isecompanycom

Key business driver for multi-interface support is traffic separation and assumption that traffic for one service that enters on interface X will return from the interfacenetwork path
bull Problem Statement
ndash Packets received on any ISE interface relies on CARS routing table to determine egress interface and next hop address
bull Solution
ndash Static routes for each endpoint subnet must be configured on each node using CLI to use the desired web service interface
ndash Source NAT to Web Portal interfaces and configure static route to NATrsquoed network
bull Considerations
ndash If NAT not used then depending on network size and addressing complexity may require hundreds of static routes to be configured very difficult to manage and maintain
ndash Dedicated interface for Anchor Controller use case should not be impacted since client IP is local (L2 adjacent) to dedicated ISE interface in DMZ

Connection Messages Explanation
Connection Failed
Please check the connection
parameters
A routing or firewall problem exists between the ISE located in the data center and the MDM located in either the
DMZ or Cloud The firewalls configuration should be checked to confirm HTTPS is allowed in this direction
Connection Failed
404 Not Found
The most likely cause of an HTML 404 error code is that an instance was configured when it was not required or
that the wrong instance has been configured
Connection Failed
403 Forbidden
The user account setup on the MDM server does not have the proper roles associated to it Validate that the
account being used by ISE is assigned the REST API MDM role
Connection Failed
401 UnauthorizedThe user name or password is not correct for the account being used by ISE
Connection Failed There is a
problem with the server
certificate or ISE Trust store
ISE does not trust the certificate presented by the MDM website This indicates the certificate was not imported to
the ISE certificate store or the certificate has expired since it was imported
The MDM Server details are
valid and the connectivity was
successful
The connection has successfully been tested The administrator should also verify the MDM AUTHZ dictionary
has been populated with attributes

bull If result of periodic recheck shows that a connected endpoint is no longer compliant ISE sends a CoA to terminate session
Survivability
bull CoA is NOT sent for devices granted access while MDM server unavailable

ndash Interface Alias Optionally assign ISE node interface (eth1 eth2 eth3) a unique hostnameFQDN which can be resolved to its local IP address using DNS
ndash Each PSN tracks which interfaces are enabled for each service and dynamically substitutes IP variable for URL redirection to the PSNs local interface alias (hostname + domain)
bull Considerations
ndash Manual configuration process from CLI
ndash Requires DNS to be updates for each alias

FQDN in SAN
60
bull Problem Statement Every ISE node requires a unique certificate
ndash New certificates signed by 3rd-party CAs can be expensive
ndash Time-consuming process to generate new certs each time new node added
ndash Certificate SAN must include FQDN entry for other web services (Sponsor MDP etc)
ndash Some endpoints require each PSN cert to be trusted and will prompt user to accept
bull Solution Wildcard Certificates
ndash Allows multiple ISE nodes to share single certificate for WebEAP authentication
ndash No longer requires custom SAN with node FQDN or interface IP addresses
ndash Most seamless and improved end-user experience
bull Considerations
ndash Less secure than unique certificate per node greater care to safeguard private key
ndash Limit exposure and deploy ISE into subdomain eg isecompanycom

Key business driver for multi-interface support is traffic separation and assumption that traffic for one service that enters on interface X will return from the interfacenetwork path
bull Problem Statement
ndash Packets received on any ISE interface relies on CARS routing table to determine egress interface and next hop address
bull Solution
ndash Static routes for each endpoint subnet must be configured on each node using CLI to use the desired web service interface
ndash Source NAT to Web Portal interfaces and configure static route to NATrsquoed network
bull Considerations
ndash If NAT not used then depending on network size and addressing complexity may require hundreds of static routes to be configured very difficult to manage and maintain
ndash Dedicated interface for Anchor Controller use case should not be impacted since client IP is local (L2 adjacent) to dedicated ISE interface in DMZ

Connection Messages Explanation
Connection Failed
Please check the connection
parameters
A routing or firewall problem exists between the ISE located in the data center and the MDM located in either the
DMZ or Cloud The firewalls configuration should be checked to confirm HTTPS is allowed in this direction
Connection Failed
404 Not Found
The most likely cause of an HTML 404 error code is that an instance was configured when it was not required or
that the wrong instance has been configured
Connection Failed
403 Forbidden
The user account setup on the MDM server does not have the proper roles associated to it Validate that the
account being used by ISE is assigned the REST API MDM role
Connection Failed
401 UnauthorizedThe user name or password is not correct for the account being used by ISE
Connection Failed There is a
problem with the server
certificate or ISE Trust store
ISE does not trust the certificate presented by the MDM website This indicates the certificate was not imported to
the ISE certificate store or the certificate has expired since it was imported
The MDM Server details are
valid and the connectivity was
successful
The connection has successfully been tested The administrator should also verify the MDM AUTHZ dictionary
has been populated with attributes

ndash Time-consuming process
ndash New certificates signed by 3rd-party CAs can be expensive
ndash Disruption to application services after new cert loaded
bull Solution
ndash Interface Alias Optionally assign ISE node interface (eth1 eth2 eth3) a unique hostnameFQDN which can be resolved to its local IP address using DNS
ndash Each PSN tracks which interfaces are enabled for each service and dynamically substitutes IP variable for URL redirection to the PSNs local interface alias (hostname + domain)

bull Problem Statement Every ISE node requires a unique certificate
ndash New certificates signed by 3rd-party CAs can be expensive
ndash Time-consuming process to generate new certs each time new node added
ndash Certificate SAN must include FQDN entry for other web services (Sponsor MDP etc)
ndash Some endpoints require each PSN cert to be trusted and will prompt user to accept
bull Solution Wildcard Certificates
ndash Allows multiple ISE nodes to share single certificate for WebEAP authentication
ndash No longer requires custom SAN with node FQDN or interface IP addresses
ndash Most seamless and improved end-user experience
bull Considerations
ndash Less secure than unique certificate per node greater care to safeguard private key
ndash Limit exposure and deploy ISE into subdomain eg isecompanycom

Key business driver for multi-interface support is traffic separation and assumption that traffic for one service that enters on interface X will return from the interfacenetwork path
bull Problem Statement
ndash Packets received on any ISE interface relies on CARS routing table to determine egress interface and next hop address
bull Solution
ndash Static routes for each endpoint subnet must be configured on each node using CLI to use the desired web service interface
ndash Source NAT to Web Portal interfaces and configure static route to NATrsquoed network
bull Considerations
ndash If NAT not used then depending on network size and addressing complexity may require hundreds of static routes to be configured very difficult to manage and maintain
ndash Dedicated interface for Anchor Controller use case should not be impacted since client IP is local (L2 adjacent) to dedicated ISE interface in DMZ

Connection Messages Explanation
Connection Failed
Please check the connection
parameters
A routing or firewall problem exists between the ISE located in the data center and the MDM located in either the
DMZ or Cloud The firewalls configuration should be checked to confirm HTTPS is allowed in this direction
Connection Failed
404 Not Found
The most likely cause of an HTML 404 error code is that an instance was configured when it was not required or
that the wrong instance has been configured
Connection Failed
403 Forbidden
The user account setup on the MDM server does not have the proper roles associated to it Validate that the
account being used by ISE is assigned the REST API MDM role
Connection Failed
401 UnauthorizedThe user name or password is not correct for the account being used by ISE
Connection Failed There is a
problem with the server
certificate or ISE Trust store
ISE does not trust the certificate presented by the MDM website This indicates the certificate was not imported to
the ISE certificate store or the certificate has expired since it was imported
The MDM Server details are
valid and the connectivity was
successful
The connection has successfully been tested The administrator should also verify the MDM AUTHZ dictionary
has been populated with attributes

Passive Reassessment
bull Bulk recheck against MDM server using configurable timer (polling interval)
bull If result of periodic recheck shows that a connected endpoint is no longer compliant ISE sends a CoA to terminate session
Survivability
bull CoA is NOT sent for devices granted access while MDM server unavailable
bull If device is granted a ldquofail openrdquo or other limited access state (for example URL-redirected to MDM) user can hit Continue button when MDM is back online to trigger CoA

ndash Disruption to application services after new cert loaded
bull Solution
ndash Interface Alias Optionally assign ISE node interface (eth1 eth2 eth3) a unique hostnameFQDN which can be resolved to its local IP address using DNS
ndash Each PSN tracks which interfaces are enabled for each service and dynamically substitutes IP variable for URL redirection to the PSNs local interface alias (hostname + domain)

Key business driver for multi-interface support is traffic separation and assumption that traffic for one service that enters on interface X will return from the interfacenetwork path
bull Problem Statement
ndash Packets received on any ISE interface relies on CARS routing table to determine egress interface and next hop address
bull Solution
ndash Static routes for each endpoint subnet must be configured on each node using CLI to use the desired web service interface
ndash Source NAT to Web Portal interfaces and configure static route to NATrsquoed network
bull Considerations
ndash If NAT not used then depending on network size and addressing complexity may require hundreds of static routes to be configured very difficult to manage and maintain
ndash Dedicated interface for Anchor Controller use case should not be impacted since client IP is local (L2 adjacent) to dedicated ISE interface in DMZ

Connection Messages Explanation
Connection Failed
Please check the connection
parameters
A routing or firewall problem exists between the ISE located in the data center and the MDM located in either the
DMZ or Cloud The firewalls configuration should be checked to confirm HTTPS is allowed in this direction
Connection Failed
404 Not Found
The most likely cause of an HTML 404 error code is that an instance was configured when it was not required or
that the wrong instance has been configured
Connection Failed
403 Forbidden
The user account setup on the MDM server does not have the proper roles associated to it Validate that the
account being used by ISE is assigned the REST API MDM role
Connection Failed
401 UnauthorizedThe user name or password is not correct for the account being used by ISE
Connection Failed There is a
problem with the server
certificate or ISE Trust store
ISE does not trust the certificate presented by the MDM website This indicates the certificate was not imported to
the ISE certificate store or the certificate has expired since it was imported
The MDM Server details are
valid and the connectivity was
successful
The connection has successfully been tested The administrator should also verify the MDM AUTHZ dictionary
has been populated with attributes

Passive Reassessment
bull Bulk recheck against MDM server using configurable timer (polling interval)
bull If result of periodic recheck shows that a connected endpoint is no longer compliant ISE sends a CoA to terminate session
Survivability
bull CoA is NOT sent for devices granted access while MDM server unavailable

bull Solution
ndash Interface Alias Optionally assign ISE node interface (eth1 eth2 eth3) a unique hostnameFQDN which can be resolved to its local IP address using DNS
ndash Each PSN tracks which interfaces are enabled for each service and dynamically substitutes IP variable for URL redirection to the PSNs local interface alias (hostname + domain)

bull Problem Statement Every ISE node requires a unique certificate
ndash New certificates signed by 3rd-party CAs can be expensive
ndash Time-consuming process to generate new certs each time new node added
ndash Certificate SAN must include FQDN entry for other web services (Sponsor MDP etc)
ndash Some endpoints require each PSN cert to be trusted and will prompt user to accept
bull Solution Wildcard Certificates
ndash Allows multiple ISE nodes to share single certificate for WebEAP authentication
ndash No longer requires custom SAN with node FQDN or interface IP addresses
ndash Most seamless and improved end-user experience

Connection Messages Explanation
Connection Failed
Please check the connection
parameters
A routing or firewall problem exists between the ISE located in the data center and the MDM located in either the
DMZ or Cloud The firewalls configuration should be checked to confirm HTTPS is allowed in this direction
Connection Failed
404 Not Found
The most likely cause of an HTML 404 error code is that an instance was configured when it was not required or
that the wrong instance has been configured
Connection Failed
403 Forbidden
The user account setup on the MDM server does not have the proper roles associated to it Validate that the
account being used by ISE is assigned the REST API MDM role
Connection Failed
401 UnauthorizedThe user name or password is not correct for the account being used by ISE
Connection Failed There is a
problem with the server
certificate or ISE Trust store
ISE does not trust the certificate presented by the MDM website This indicates the certificate was not imported to
the ISE certificate store or the certificate has expired since it was imported
The MDM Server details are
valid and the connectivity was
successful
The connection has successfully been tested The administrator should also verify the MDM AUTHZ dictionary
has been populated with attributes

FQDN in SAN
60
bull Problem Statement Every ISE node requires a unique certificate
ndash New certificates signed by 3rd-party CAs can be expensive
ndash Time-consuming process to generate new certs each time new node added
ndash Certificate SAN must include FQDN entry for other web services (Sponsor MDP etc)
ndash Some endpoints require each PSN cert to be trusted and will prompt user to accept
bull Solution Wildcard Certificates
ndash Allows multiple ISE nodes to share single certificate for WebEAP authentication
ndash No longer requires custom SAN with node FQDN or interface IP addresses
ndash Most seamless and improved end-user experience
bull Considerations
ndash Less secure than unique certificate per node greater care to safeguard private key
ndash Limit exposure and deploy ISE into subdomain eg isecompanycom

Key business driver for multi-interface support is traffic separation and assumption that traffic for one service that enters on interface X will return from the interfacenetwork path
bull Problem Statement
ndash Packets received on any ISE interface relies on CARS routing table to determine egress interface and next hop address
bull Solution
ndash Static routes for each endpoint subnet must be configured on each node using CLI to use the desired web service interface
ndash Source NAT to Web Portal interfaces and configure static route to NATrsquoed network
bull Considerations
ndash If NAT not used then depending on network size and addressing complexity may require hundreds of static routes to be configured very difficult to manage and maintain
ndash Dedicated interface for Anchor Controller use case should not be impacted since client IP is local (L2 adjacent) to dedicated ISE interface in DMZ

Connection Messages Explanation
Connection Failed
Please check the connection
parameters
A routing or firewall problem exists between the ISE located in the data center and the MDM located in either the
DMZ or Cloud The firewalls configuration should be checked to confirm HTTPS is allowed in this direction
Connection Failed
404 Not Found
The most likely cause of an HTML 404 error code is that an instance was configured when it was not required or
that the wrong instance has been configured
Connection Failed
403 Forbidden
The user account setup on the MDM server does not have the proper roles associated to it Validate that the
account being used by ISE is assigned the REST API MDM role
Connection Failed
401 UnauthorizedThe user name or password is not correct for the account being used by ISE
Connection Failed There is a
problem with the server
certificate or ISE Trust store
ISE does not trust the certificate presented by the MDM website This indicates the certificate was not imported to
the ISE certificate store or the certificate has expired since it was imported
The MDM Server details are
valid and the connectivity was
successful
The connection has successfully been tested The administrator should also verify the MDM AUTHZ dictionary
has been populated with attributes

bull If result of periodic recheck shows that a connected endpoint is no longer compliant ISE sends a CoA to terminate session
Survivability
bull CoA is NOT sent for devices granted access while MDM server unavailable

bull Problem Statement Every ISE node requires a unique certificate
ndash New certificates signed by 3rd-party CAs can be expensive
ndash Time-consuming process to generate new certs each time new node added
ndash Certificate SAN must include FQDN entry for other web services (Sponsor MDP etc)
ndash Some endpoints require each PSN cert to be trusted and will prompt user to accept
bull Solution Wildcard Certificates
ndash Allows multiple ISE nodes to share single certificate for WebEAP authentication
ndash No longer requires custom SAN with node FQDN or interface IP addresses
ndash Most seamless and improved end-user experience
bull Considerations
ndash Less secure than unique certificate per node greater care to safeguard private key
ndash Limit exposure and deploy ISE into subdomain eg isecompanycom

Key business driver for multi-interface support is traffic separation and assumption that traffic for one service that enters on interface X will return from the interfacenetwork path
bull Problem Statement
ndash Packets received on any ISE interface relies on CARS routing table to determine egress interface and next hop address
bull Solution
ndash Static routes for each endpoint subnet must be configured on each node using CLI to use the desired web service interface
ndash Source NAT to Web Portal interfaces and configure static route to NATrsquoed network
bull Considerations
ndash If NAT not used then depending on network size and addressing complexity may require hundreds of static routes to be configured very difficult to manage and maintain
ndash Dedicated interface for Anchor Controller use case should not be impacted since client IP is local (L2 adjacent) to dedicated ISE interface in DMZ

FQDN in SAN
60
bull Problem Statement Every ISE node requires a unique certificate
ndash New certificates signed by 3rd-party CAs can be expensive
ndash Time-consuming process to generate new certs each time new node added
ndash Certificate SAN must include FQDN entry for other web services (Sponsor MDP etc)
ndash Some endpoints require each PSN cert to be trusted and will prompt user to accept
bull Solution Wildcard Certificates
ndash Allows multiple ISE nodes to share single certificate for WebEAP authentication
ndash No longer requires custom SAN with node FQDN or interface IP addresses
ndash Most seamless and improved end-user experience
bull Considerations
ndash Less secure than unique certificate per node greater care to safeguard private key
ndash Limit exposure and deploy ISE into subdomain eg isecompanycom

Key business driver for multi-interface support is traffic separation and assumption that traffic for one service that enters on interface X will return from the interfacenetwork path
bull Problem Statement
ndash Packets received on any ISE interface relies on CARS routing table to determine egress interface and next hop address
bull Solution
ndash Static routes for each endpoint subnet must be configured on each node using CLI to use the desired web service interface
ndash Source NAT to Web Portal interfaces and configure static route to NATrsquoed network
bull Considerations
ndash If NAT not used then depending on network size and addressing complexity may require hundreds of static routes to be configured very difficult to manage and maintain
ndash Dedicated interface for Anchor Controller use case should not be impacted since client IP is local (L2 adjacent) to dedicated ISE interface in DMZ

Connection Messages Explanation
Connection Failed
Please check the connection
parameters
A routing or firewall problem exists between the ISE located in the data center and the MDM located in either the
DMZ or Cloud The firewalls configuration should be checked to confirm HTTPS is allowed in this direction
Connection Failed
404 Not Found
The most likely cause of an HTML 404 error code is that an instance was configured when it was not required or
that the wrong instance has been configured
Connection Failed
403 Forbidden
The user account setup on the MDM server does not have the proper roles associated to it Validate that the
account being used by ISE is assigned the REST API MDM role
Connection Failed
401 UnauthorizedThe user name or password is not correct for the account being used by ISE
Connection Failed There is a
problem with the server
certificate or ISE Trust store
ISE does not trust the certificate presented by the MDM website This indicates the certificate was not imported to
the ISE certificate store or the certificate has expired since it was imported
The MDM Server details are
valid and the connectivity was
successful
The connection has successfully been tested The administrator should also verify the MDM AUTHZ dictionary
has been populated with attributes

Key business driver for multi-interface support is traffic separation and assumption that traffic for one service that enters on interface X will return from the interfacenetwork path
bull Problem Statement
ndash Packets received on any ISE interface relies on CARS routing table to determine egress interface and next hop address
bull Solution
ndash Static routes for each endpoint subnet must be configured on each node using CLI to use the desired web service interface
ndash Source NAT to Web Portal interfaces and configure static route to NATrsquoed network
bull Considerations
ndash If NAT not used then depending on network size and addressing complexity may require hundreds of static routes to be configured very difficult to manage and maintain
ndash Dedicated interface for Anchor Controller use case should not be impacted since client IP is local (L2 adjacent) to dedicated ISE interface in DMZ

ISE ndash MDM configuration most common issues
Connection Messages Explanation
Connection Failed
Please check the connection
parameters
A routing or firewall problem exists between the ISE located in the data center and the MDM located in either the
DMZ or Cloud The firewalls configuration should be checked to confirm HTTPS is allowed in this direction
Connection Failed
404 Not Found
The most likely cause of an HTML 404 error code is that an instance was configured when it was not required or
that the wrong instance has been configured
Connection Failed
403 Forbidden
The user account setup on the MDM server does not have the proper roles associated to it Validate that the
account being used by ISE is assigned the REST API MDM role
Connection Failed
401 UnauthorizedThe user name or password is not correct for the account being used by ISE
Connection Failed There is a
problem with the server
certificate or ISE Trust store
ISE does not trust the certificate presented by the MDM website This indicates the certificate was not imported to
the ISE certificate store or the certificate has expired since it was imported
The MDM Server details are
valid and the connectivity was
successful
The connection has successfully been tested The administrator should also verify the MDM AUTHZ dictionary
has been populated with attributes

ISE ndash MDM IntegrationScalability
bull Scalability = 30 API calls per second ( gt100`000 callsh)Consider Internet bandwidth and latency for cloud-based solutions
Passive Reassessment
bull Bulk recheck against MDM server using configurable timer (polling interval)
bull If result of periodic recheck shows that a connected endpoint is no longer compliant ISE sends a CoA to terminate session
Survivability
bull CoA is NOT sent for devices granted access while MDM server unavailable
bull If device is granted a ldquofail openrdquo or other limited access state (for example URL-redirected to MDM) user can hit Continue button when MDM is back online to trigger CoA

Key business driver for multi-interface support is traffic separation and assumption that traffic for one service that enters on interface X will return from the interfacenetwork path
bull Problem Statement
ndash Packets received on any ISE interface relies on CARS routing table to determine egress interface and next hop address
bull Solution
ndash Static routes for each endpoint subnet must be configured on each node using CLI to use the desired web service interface
ndash Source NAT to Web Portal interfaces and configure static route to NATrsquoed network
bull Considerations
ndash If NAT not used then depending on network size and addressing complexity may require hundreds of static routes to be configured very difficult to manage and maintain
ndash Dedicated interface for Anchor Controller use case should not be impacted since client IP is local (L2 adjacent) to dedicated ISE interface in DMZ

Key business driver for multi-interface support is traffic separation and assumption that traffic for one service that enters on interface X will return from the interfacenetwork path
bull Problem Statement
ndash Packets received on any ISE interface relies on CARS routing table to determine egress interface and next hop address
bull Solution
ndash Static routes for each endpoint subnet must be configured on each node using CLI to use the desired web service interface
ndash Source NAT to Web Portal interfaces and configure static route to NATrsquoed network
bull Considerations
ndash If NAT not used then depending on network size and addressing complexity may require hundreds of static routes to be configured very difficult to manage and maintain
ndash Dedicated interface for Anchor Controller use case should not be impacted since client IP is local (L2 adjacent) to dedicated ISE interface in DMZ

Connection Messages Explanation
Connection Failed
Please check the connection
parameters
A routing or firewall problem exists between the ISE located in the data center and the MDM located in either the
DMZ or Cloud The firewalls configuration should be checked to confirm HTTPS is allowed in this direction
Connection Failed
404 Not Found
The most likely cause of an HTML 404 error code is that an instance was configured when it was not required or
that the wrong instance has been configured
Connection Failed
403 Forbidden
The user account setup on the MDM server does not have the proper roles associated to it Validate that the
account being used by ISE is assigned the REST API MDM role
Connection Failed
401 UnauthorizedThe user name or password is not correct for the account being used by ISE
Connection Failed There is a
problem with the server
certificate or ISE Trust store
ISE does not trust the certificate presented by the MDM website This indicates the certificate was not imported to
the ISE certificate store or the certificate has expired since it was imported
The MDM Server details are
valid and the connectivity was
successful
The connection has successfully been tested The administrator should also verify the MDM AUTHZ dictionary
has been populated with attributes

bull Scalability = 30 API calls per second ( gt100`000 callsh)Consider Internet bandwidth and latency for cloud-based solutions
Passive Reassessment
bull Bulk recheck against MDM server using configurable timer (polling interval)
bull If result of periodic recheck shows that a connected endpoint is no longer compliant ISE sends a CoA to terminate session
Survivability
bull CoA is NOT sent for devices granted access while MDM server unavailable
bull If device is granted a ldquofail openrdquo or other limited access state (for example URL-redirected to MDM) user can hit Continue button when MDM is back online to trigger CoA

Connection Messages Explanation
Connection Failed
Please check the connection
parameters
A routing or firewall problem exists between the ISE located in the data center and the MDM located in either the
DMZ or Cloud The firewalls configuration should be checked to confirm HTTPS is allowed in this direction
Connection Failed
404 Not Found
The most likely cause of an HTML 404 error code is that an instance was configured when it was not required or
that the wrong instance has been configured
Connection Failed
403 Forbidden
The user account setup on the MDM server does not have the proper roles associated to it Validate that the
account being used by ISE is assigned the REST API MDM role
Connection Failed
401 UnauthorizedThe user name or password is not correct for the account being used by ISE
Connection Failed There is a
problem with the server
certificate or ISE Trust store
ISE does not trust the certificate presented by the MDM website This indicates the certificate was not imported to
the ISE certificate store or the certificate has expired since it was imported
The MDM Server details are
valid and the connectivity was
successful
The connection has successfully been tested The administrator should also verify the MDM AUTHZ dictionary
has been populated with attributes

Connection Messages Explanation
Connection Failed
Please check the connection
parameters
A routing or firewall problem exists between the ISE located in the data center and the MDM located in either the
DMZ or Cloud The firewalls configuration should be checked to confirm HTTPS is allowed in this direction
Connection Failed
404 Not Found
The most likely cause of an HTML 404 error code is that an instance was configured when it was not required or
that the wrong instance has been configured
Connection Failed
403 Forbidden
The user account setup on the MDM server does not have the proper roles associated to it Validate that the
account being used by ISE is assigned the REST API MDM role
Connection Failed
401 UnauthorizedThe user name or password is not correct for the account being used by ISE
Connection Failed There is a
problem with the server
certificate or ISE Trust store
ISE does not trust the certificate presented by the MDM website This indicates the certificate was not imported to
the ISE certificate store or the certificate has expired since it was imported
The MDM Server details are
valid and the connectivity was
successful
The connection has successfully been tested The administrator should also verify the MDM AUTHZ dictionary
has been populated with attributes

ISE ndash MDM IntegrationScalability
bull Scalability = 30 API calls per second ( gt100`000 callsh)Consider Internet bandwidth and latency for cloud-based solutions
Passive Reassessment
bull Bulk recheck against MDM server using configurable timer (polling interval)
bull If result of periodic recheck shows that a connected endpoint is no longer compliant ISE sends a CoA to terminate session
Survivability
bull CoA is NOT sent for devices granted access while MDM server unavailable
bull If device is granted a ldquofail openrdquo or other limited access state (for example URL-redirected to MDM) user can hit Continue button when MDM is back online to trigger CoA

Connection Messages Explanation
Connection Failed
Please check the connection
parameters
A routing or firewall problem exists between the ISE located in the data center and the MDM located in either the
DMZ or Cloud The firewalls configuration should be checked to confirm HTTPS is allowed in this direction
Connection Failed
404 Not Found
The most likely cause of an HTML 404 error code is that an instance was configured when it was not required or
that the wrong instance has been configured
Connection Failed
403 Forbidden
The user account setup on the MDM server does not have the proper roles associated to it Validate that the
account being used by ISE is assigned the REST API MDM role
Connection Failed
401 UnauthorizedThe user name or password is not correct for the account being used by ISE
Connection Failed There is a
problem with the server
certificate or ISE Trust store
ISE does not trust the certificate presented by the MDM website This indicates the certificate was not imported to
the ISE certificate store or the certificate has expired since it was imported
The MDM Server details are
valid and the connectivity was
successful
The connection has successfully been tested The administrator should also verify the MDM AUTHZ dictionary
has been populated with attributes

Connection Messages Explanation
Connection Failed
Please check the connection
parameters
A routing or firewall problem exists between the ISE located in the data center and the MDM located in either the
DMZ or Cloud The firewalls configuration should be checked to confirm HTTPS is allowed in this direction
Connection Failed
404 Not Found
The most likely cause of an HTML 404 error code is that an instance was configured when it was not required or
that the wrong instance has been configured
Connection Failed
403 Forbidden
The user account setup on the MDM server does not have the proper roles associated to it Validate that the
account being used by ISE is assigned the REST API MDM role
Connection Failed
401 UnauthorizedThe user name or password is not correct for the account being used by ISE
Connection Failed There is a
problem with the server
certificate or ISE Trust store
ISE does not trust the certificate presented by the MDM website This indicates the certificate was not imported to
the ISE certificate store or the certificate has expired since it was imported
The MDM Server details are
valid and the connectivity was
successful
The connection has successfully been tested The administrator should also verify the MDM AUTHZ dictionary
has been populated with attributes

Connection Messages Explanation
Connection Failed
Please check the connection
parameters
A routing or firewall problem exists between the ISE located in the data center and the MDM located in either the
DMZ or Cloud The firewalls configuration should be checked to confirm HTTPS is allowed in this direction
Connection Failed
404 Not Found
The most likely cause of an HTML 404 error code is that an instance was configured when it was not required or
that the wrong instance has been configured
Connection Failed
403 Forbidden
The user account setup on the MDM server does not have the proper roles associated to it Validate that the
account being used by ISE is assigned the REST API MDM role
Connection Failed
401 UnauthorizedThe user name or password is not correct for the account being used by ISE
Connection Failed There is a
problem with the server
certificate or ISE Trust store
ISE does not trust the certificate presented by the MDM website This indicates the certificate was not imported to
the ISE certificate store or the certificate has expired since it was imported
The MDM Server details are
valid and the connectivity was
successful
The connection has successfully been tested The administrator should also verify the MDM AUTHZ dictionary
has been populated with attributes

ISE ndash MDM IntegrationScalability
bull Scalability = 30 API calls per second ( gt100`000 callsh)Consider Internet bandwidth and latency for cloud-based solutions
Passive Reassessment
bull Bulk recheck against MDM server using configurable timer (polling interval)
bull If result of periodic recheck shows that a connected endpoint is no longer compliant ISE sends a CoA to terminate session
Survivability
bull CoA is NOT sent for devices granted access while MDM server unavailable
bull If device is granted a ldquofail openrdquo or other limited access state (for example URL-redirected to MDM) user can hit Continue button when MDM is back online to trigger CoA
