IES ServiceAn Internet Enhanced Service (IES) is a routed connectivity service where the subscribercommunicates with an IP (Layer 3) router interface to send and receive Internet traffic.The 7750 SR buffers service traffic and shapes it to conform to SLA parameters. Buffer allocation isprogrammable per-service to accommodate different maximum burst sizes (MBS). Each service canuse multiple queues to enable shaping, policing and marking of different flows. The 7750 SR canalso shape and police on service egress so customers can purchase sub-rate services (e.g. Internetservices) with asymmetric SLAs.

Characteristics Service Access Point (SAP) acts as the access point to the subscriber’s network SAP supports multiple encapsulation types, such as: Ethernet null, dot1q, q-in-q, SONET/SDH-

IPCP, BCP-null, BCP-dot1q and ATM. Supports VRRP, Cflowd, secondary IP addresses, and ICMP options on customer IP interfaces Interface supports RIP, OSPF, IS-IS, and BGP. QoS and filter policies Does not require a Service Distribution Path (SDP); traffic is routed rather than being

encapsulated in a tunnel

Services must be associated with a customer. Though a service may only have one customer, that customer

may have more than one associated to them.

To create a Customer using the 5620 SAM, the network administrator or operator will use the followingsequence:

From the Main Menu, select Manage Customers In the new window, click on the Create button Complete the customer’s details as provided in the configuration window Click on the OK button.

To verify that the customer was created, or edit any detail: Select Manage Customers from the Main Menu Click on the Search button

Double-click on the appropriate entry or, select the appropriate customer and click on the Edit button. Review or modify the details, as required. Click OK or Apply to save the changes or Cancel to disregard any modifications and close the window.

Configure Access Port

As discussed, a service requires a port facing the customer edge to be configured for Access and an

Encapsulation type specified. To configure a port:

Navigate to the Equipment view in the Navigation Tree

Expand the tree and select the appropriate port or ports. It is possible to configure multiple ports at thesame time by through the Shift – Click or Ctrl – Click method.

Right-click and select Properties from the contextual menu

From the Mode drop-down menu, select Access

From the Encapsulation Type drop-down menu, select the appropriate encapsulation type

Set the port MTU. Remember that the port MTU must be set to a value set to support the largest serviceMTU to be supported on that port.

Select OK to complete the configuration.

To create a service, select the service type and assign the managed devices upon which the service will

terminate, referred to as the Service Sites.

To create an IES:

Select Create Service IES from the Main Menu

Click the Select button in the Customer block

Select a customer from the list that appears and click the OK button

Complete the remaining parameters, as required. Though optional, providing a service name and relevantdescription will enable the network administrator or operator to find the service more quickly using theSearch filter.

Create Service Site(s)

1.Click on Sites tab2.Select Add

3. Add site

Having clicked the Apply button, the configuration window remains open and the changes are saved in the

5620 SAM database. However, service components (Service Sites, Access Interfaces and SDP Bindings) haveyet to be configured for the service to be commissioned.

To configure service sites: Navigate to the Components window of the service configuration form Select IES and right-click Select Create Site and select the sites to participate in the VPLS service from the list. This may be done

individually or by selecting multiple entries at once. Click the OK button on the bottom of the Components window (i.e., the containing window in this case) Confirm the sites have been added in the Components window

It is important to remember that, even though they appear in the configuration window, the changes will notbe sent to the managed devices and saved to the 5620 SAM database until the OK or Apply button at the

bottom of the window (referred to as the Containing Window) is clicked.

Create L3 Interface

Service Access Points are virtual interfaces to provide customer access to the service provider’s network. An

SAP consists of: a physical port configured to support Access points; an encapsulation type; and, anencapsulation ID value unique to the port.

To create a SAP:

Navigate to the Component window for the service.

Navigate to the Access Interface of the appropriate Site.

Right-click and select Create L3 Access Interface.

Assign an interface name (mandatory) and complete the remaining parameters, as required.

Click the Port tab and then click the Select button.

Click the Search button. All Access ports on the managed device will appear in the list. Select theappropriate port and click the OK button.

Create L3 Access Interface (SAP) [Cont.]

Encapsulation Value, as required

The SAP also requires an encapsulation ID value that is unique to the port upon which it is being created. To

assign an encapsulation ID: Select the Port tab. Assign the Outer Encapsulation Value and Inner Encapsulation Value, as required. The use of

encapsulation values will be determined by the encapsulation type configured on the port being used. Thiswas set during the process to create an Access port, discussed earlier in the course.

Select the Address tab.


12/18





8 · 4 · 12

Create L3 Access Interface (SAP) [Cont.]

An IES is a Layer 3 service and will therefore require an IP Address on the SAP. To assign an IP

address to the SAP: Open the Address tab in the service configuration window Click on the Add button Enter the appropriate IP address according to scheme provided. The Address ID determines

whether the IP address is either the primary (ID # 1) or a secondary address (ID# 2 – 16). Configure the parameters under the remaining windows, as required. These are optional settingsand may be added at any time in the future without service interruption. These parametersinclude:

QoS: assign access ingress and egress policies

Schedulers: assign ingress and egress schedulers for HQoS

ACL: assign ingress and egress filter policies

Accounting: define an accounting policy

ICMP: define type and rate that ICMP messages will be processed on this interface

ARP: define static entries in the ARP table. Turn on Proxy ARP and define proxy ARP policies

DHCP: configure DHCP relay, Option 82 and the DHCP lease state table.

Anti-Spoofing: turn on auto creation of anti-spoofing filters and configure static hosts

Click on OK or Apply to complete the configuration

Opening the Components tab will provide a tabular view of the service configuration. Expand theAccess Interface entry to confirm that the SAP has been created and verify that its statusindicates that the interface is Up.

Add SAP to Internal Gateway Protocol (IGP )

OK

Though the IES has been created, traffic will not be forwarded through the interface until itparticipates in the Internal Gateway Protocol’s routing table. To do so, the interface must beassigned to an Internal Gateway Protocol (IGP) including an appropriate area or autonomoussystem, as required by the protocol.

To configure the IES interface to participate in the IGP route table:

Open the Components tab of the IES

Navigate to the IES Access Interface and select the appropriate SAP.

Right-click and select Properties from the contextual menu

In the window that appears (L3 Access Interface), select the Protocols tab

Select the Add button.

The Create Interface window appears. From the drop-down menu, select the appropriate protocolto which the interface will be added and click OK . Repeat this process for each of the IGP in which

this interface is to participate.The protocol(s) will appear in the list.

Select OK to complete the configuration and deploy the changes to the 5620 SAM database andnetwork element(s).

The IES will now be able to pass traffic through the SAP.

In the new window (L3 Access Interface), click on the Select button in the Routing Instanceportion of the configuration window

List the available routing instances by clicking on the Search button. Using Search filters canrefine the list.

Select the appropriate routing instance from the list and click OK

Protocol Properties

As part of the service provider’s policy in providing the IES, it may be necessary to modify thedefault actions of the IGP on this interface. For example, the IES interface may be used to providerouting to another carrier’s network, in which case, it may be desirable to prevent the exchangeof routing tables by configuring the interface for Passive mode.

To modify the IGP properties for an IES interface:

Navigate to and select the IES SAP in the Components tab of the service.

Select the Properties from the contextual menu.

Select the Protocols tab, select the protocol instance and then select the Properties button,which will open the OSPF Interface window.

Click on the Protocol Properties tab.

Configure the parameters, as require and then click on OK at the bottom of the list to save the

changes.

Manage IES

Once created, the network administrator or operator is able to view and/ or manage the IES fromthe 5620 SAM GUI.

To manage or view the IES service configuration:

Select Manage Services from the Main Menu

Set the Search filter parameters, as required

Click on the Search button

Select the service from the list, and double click on the service.

The configuration window appears on the screen. Service configuration information is providedunder the appropriate tabs listed at the top of the window. Parameters in drop-down menus or inthe white blocks may be changed. Changes to an existing service will prompt a warning to which

the network administrator or operator will be required to acknowledge before changes will beaffected.

Viewing a graphical representation of the service is possible by clicking on the Topology Viewbutton of either window. An example is provided on the next page.
