History of Network Automation
Generation 0 – Scripting by A Few
Automate Inventory and basic health
check
Perl, Python and Expect/TCL scripting
Generation 1 – NCCM Tools for Some
Automate Change and Configuration
HPNA (Opsware), EMC Voyence, Alterpoint,
CiscoPrime
What About Other Manual Tasks? For Most of Us?
Network Documentation – Pen and Paper and Visio
Troubleshooting & Analysis – Command
Line Digging & Configure
?G0: Scripting G1: NCCM for Configuration G2: The Rest?

Map-data
Automatic Legend
o NetBrain Qmaps can be created on demand instantly
Create a map around an IP address Map an application path
o Qmaps are data rich and interactive Zoom in to see more network data and
observe device details (Observer) Encapsulate built-in data, show command
results, and monitored data inside a Qmap
o Qmaps can be automatically updated Highlight any topology changes on the map Schedule an auto update of maps
Introduce Dynamic Map (Qmap)
Dynamic Map – Zooming
Scroll with a wheel mouse or setting the zoom % manually At customizable zoom %, data layers dynamically add or removed
from the map Select Options on the Map ribbon to adjust defaults
Zoom = 80%
Zoom = 160%
Dynamic Map – Zoom to Relevant Maps
Zoom out to reduce the amount of labels on the map Zoom out to 40% on any Qmap to launch the relevant search Double-click on the desired map to open in a new tab
Relevant Router in new Qmap
Zoom in to 300% to launch Observer Panel Continue zooming in to scroll through each card Each card provides easy access to information related to a device Uses and to change to a different device on the map
Dynamic Map – Zoom to Observer Cards
Dive into a Device via Observer
Navigator card allows re-ordering and hiding of each card Click “Refresh” on Design card to clean un-used categories
Description» Provides access to logical
configuration blocks» Use NetBrain algorithms to
group parsed protocol and related information
Design Reader
Use Case:» Compare neighboring protocol configurations» Compare neighboring interface settings
How to launch» Select a device of interest on the map» Select Config>Design Reader from floating Qmap menu
Using the Design Reader
Navigate the design reader tree on left for desired configuration block Change the “Source of Configuration” data for historical comparison Select the hostname hyperlink to change device for comparison
Using the Design Reader (cont)
Click on the top row of the design reader tree to validate configuration blocks
no matching configuration, matching configuration available Launches sample configuration viewer
Show sample configuration
More Ways to Map On-Demand
Search for the server and map adjacent LAN environment to see where it connects
o Find and disable an infected server Map targeted routing domain (e.g. OSPF 200)
o Troubleshoot OSPF routing issues
Map related Downstream Source Tree
o Troubleshoot multicast video issues Open Layer-2 Map of Data Center
o Troubleshoot a Data Center
Case Studies
British Telecom Saves Over $1 Million with Dynamic Mapping
With NetBrain, BT significantly reduced costs and manpower associated with discovery and diagramming of its customer’s 20,000 node network. BT scheduled automated bi-monthly rediscovery and asset reports to outline ongoing changes.
Fidelity Investments Cuts MTTR in Half with Dynamic Mapping
Fidelity utilized NetBrain to automate diagram creation, visualize performance issues, and easily share information for collaborative troubleshooting sessions. Dynamic Mapping shortened typical diagnosis and repair by as much as 50%.
Thompson Reuters Consolidates Three Data Centers with Zero Outages
Thompson Reuters was able to reduce costs associated with data collection, data center consolidation, and resultant downtime. Additionally, they were able to increase the accuracy of their change management process with NetBrain.
“NetBrain is a game-changer for documenting large
networks.”

“Troubleshooting without NetBrain is like
troubleshooting in the dark.”
