1. Automation Procedures
NetBrain procedures can automate any series of actions normally completed using the command line interface.
1. Use procedures to automate a wide range of network tasks:
a) .Troubleshooting – Any troubleshooting logic can be translated into an executable and repeatable process
b) Change Verification – Test the network after changes, e.g. ping multiple servers, test application flows, etc.
c) .Compliance – Check config compliance, e.g. ‘Is password encrypted?’ or ‘Is public community string used?’
d) .Mapping – Create customized maps and parse CLI output to the map, e.g. ‘Map multicasting tree’ or ‘Highlight VTP
Domain’.
e) Traffic Path Analysis – Map across devices such as load balancers or firewalls
f) Customized Inventory Reports – Dynamically add fields to the inventory database such as IOS Image File.
2. Hundreds of procedures ‘out of the box’ to automate repetitive and difficult tasks, such as:
a) Detect interface errors, speed/duplex mismatches, MTU mismatches
b) Check routing neighbors, QoS queue drop
c) Verify changes, such as configuration, multicasting distribution tree, HSRP roles, etc.
3. Create your own procedures in minutes. No scripting experience required.
a) Build once, execute anywhere, any time
b) Build and share a knowledge database on how to troubleshoot common network problems
4. Run multiple procedures on hundreds of devices simultaneously. Select as many procedures as you like and indicate how many devices to include. Then click ‘Run’.
NetBrain Technologies, Inc. New Feature Guide: Consultant Edition v5.0 4
Procedure Example 1:
Are Interface Errors Increasing?
Logic: Retrieve ‘show interface’ command twice and calculate the delta of each parameter. If delta is greater than 0, report error and highlight on map.
NetBrain Technologies, Inc. New Feature Guide: Consultant Edition v5.0 5
Procedure Example 2:
Has Root Bridge Changed?
Logic: Issue ‘show spanning-tree’ against historic benchmark data and against live network. If Root ID has changed, raise alert and highlight on the map.
NetBrain Technologies, Inc. New Feature Guide: Consultant Edition v5.0 6
Procedure Example 3:
Map Multicasting Distribution Tree
Logic: Leverage the following commands to map the downstream source tree: Show ip mroute <group> Show ip pim neighbor Show ip igmp group
NetBrain Technologies, Inc. New Feature Guide: Consultant Edition v5.0 7
Procedure Example 4:
Automate Ping to a Group of End Hosts
Logic: Execute a ping from specified network devices to a group of end hosts. If ping fails, provide the source and destination of the failure.
NetBrain Technologies, Inc. New Feature Guide: Consultant Edition v5.0 8
Procedure Example 5:
Enhance Traffic Path Mapping Logic Logic: 1. Check output VRF 2. Find non-default route to destination 3. Find default route
Related Commands: 1. Show ip vrf 2. Show ip route vrf vrf_name x.x.x.x
NetBrain Technologies, Inc. New Feature Guide: Consultant Edition v5.0 9
Procedure Example 6:
Inventory Device IOS Image Status
This procedure is used to add the <IOS Image File> attribute to the device properties.
Logic: Retrieve ‘show version’, parse the system image file information.

Build Your Own Procedures
in Minutes
NetBrain comes with hundreds of procedures built in. You can also customize your own with a visual ‘sample-driven’ platform. There are three components:
1. Probes – Define how to retrieve live data from network devices
2. Parsers – Define how to parse CLI command outputs
3. Triggers – Define how to analyze the results and provide user feedback
NetBrain Technologies, Inc. New Feature Guide: Consultant Edition v5.0 11
2. Traffic Path Analysis
Networks are designed to move traffic from A to B. NetBrain CE 5.0 allows users to visualize and analyze these dynamic traffic paths across complex networks, factoring:
1. Dynamic and Static Routing
2. Network Address Translation (NAT)
3. Both L3 and L2 Traffic Flow
A historical view of traffic paths is also available, so that users can visually compare traffic flow between the past and present
Simply specify a source and destination IP address or hostname and click ‘Find Path’
L2/L3 Traffic Path between Two Points
NetBrain Technologies, Inc. New Feature Guide: Consultant Edition v5.0 12
Map Live Traffic Path
During real-time troubleshooting, it’s important to know how traffic moves across the live network. Live traffic path analysis retrieves live data to discover the path including:
Routing Tables
Configuration Files
CAM/ARP Tables
The network design behind traffic paths is also decoded including:
ACL, QoS, NAT
Dynamic/Static Routing & PBR
VRF, Multicasting
Switch port speed and duplex
settings
Traffic Path of the Live Network
NetBrain Technologies, Inc. New Feature Guide: Consultant Edition v5.0 13
Map Historical Traffic Path
A key question when analyzing a network is, ‘what was the path like before?’. Leveraging historical benchmark data, users can map L3 and L2 traffic paths of the past.
By overlaying two paths in a single map, (live and historical), users can visualize the changes in traffic flow. Compare Historical and Live Paths
NetBrain Technologies, Inc. New Feature Guide: Consultant Edition v5.0 14
3. Visual Monitoring
Visual monitoring is a powerful troubleshooting tool. It is different from traditional network
monitoring:
It uses a dynamic map as the launching pad to start and stop monitoring
Real-time data collected from the live network is displayed in the map, along with alarms
Visual network monitoring can poll
many types of data such as:
Device & port up/down status
Link error
Link delay
Packet drop
The interval and alarm thresholds are configurable.
Monitor connectivity and performance directly from the map
NetBrain Technologies, Inc. New Feature Guide: Consultant Edition v5.0 15
NetBrain’s change management workflow is an integrated solution that makes network changes more efficient and less risky:
Define Network Changes – Design network changes in the map and define changes with a template-driven approach
Automatically Push Changes – Indicate which devices will be impacted and execute the changes with one-click. Watch
the configuration happen live.
Analyze the Impact of Changes – Automatically compare configurations, route tables, and CLI output from before and
after executing the changes.
Automatically Document – Export every detail of the network change to a Word document. It includes the impacted
devices, config changes made, time stamps, and much more.
4. Map-Driven Change Management

models (Introduced in V4.2)
Users can customize the software to support any
device
Define device type and driver for retrieving and parsing
live data

device driver
NetBrain Technologies, Inc. New Feature Guide: Consultant Edition v5.0 17
6a. Feature Improvement
MPLS Cloud
NetBrain 5.0 can calculate virtual routing tables for MPLS clouds based on advertised route
data from BGP CE devices. This is more accurate and efficient than the previous algorithm.
It is now possible to highlight neighbor information for the CE devices which connected with
the MPLS cloud. From the map, use the ‘highlight routing protocol’ feature.
NetBrain Technologies, Inc. New Feature Guide: Consultant Edition v5.0 18
Dynamic network data is better organized in the Map Data Pane.
Configuration files, show-command data, attachment files, and recorded monitoring data
Drag and drop files into the pane to add an attachment
Drag show-command data to create a hyperlink to the data in the map
6b. Feature Improvement:
New Map Data Pane
NetBrain Technologies, Inc. New Feature Guide: Consultant Edition v5.0 19
6c. Other Improvements
1. Layer-2 Discovery Improvements
Support for non-CDP LAN gateway devices, e.g. Firewall devices
Filter DHCP entries of L2 One-IP table optionally, which reduces the size of the table and accelerates workspace synchronization
Discover L2 topology of LWAP
Support VRF ARP table in L2 discovery
Get interface MAC address from gateway ARP table if SNMP tuning fails
2. Live Access Improvements
Improve Scheduled Rediscovery feature to support importing CLI data from folder or FTP server.
» Allows NetBrain to retrieve live network data via 3rd party systems (e.g. HP Opsware)
Support Regular Expression Logic in login script (expect what)
Improve Device Setting and Network Setting
» Add ‘privilege username and prompt’ for login privilege mode (necessary for Brocade switch support)
