Map + App

o Troubleshoot with automation

Instantly create a dynamic network map to identify the segment of the network responsible for forwarding the application traffic. Then drill down with apps for further diagnosis.

Network Performance

Routing Changes

ConfigurationDiscrepancies

Build a Map

o Visualize the application flow across the network with a targeted map created from a pair of source and destination addresses of the application

Asymmetric Routing

o Map reverse flow path to see how traffic flows from B to A.

Run Apps

o Analyze application performance & design dependencies

by collecting performance and configuration data with an app.

o Recommended App: Layer-4 Port-Level Analysis

Specify layer-4 protocol and port number to identify traffic forwarding rules and restrictions specific to defined port.

Run Apps

o Discover changes in traffic flow with an app to identify changes in topology by mapping the flow as it looked previously.

Run Apps

o Monitor network health

by letting the app perform a continuous scan of the relevant network to determine device availability, device health, and link performance.

Run Apps

o The app will also generate alarms when threshold is exceeded.

Run Apps

o Leverage the Netflow app

to analyze bandwidth bottlenecks and drill down into interface’s bandwidth utilization data to see relevant Netflow data.

Write Your Own Apps

o To automate any troubleshooting diagnosis

Create an app rather than issuing show commands one-by-one across devices.

Write Your Own Apps

o Define variables of interest

One example is to use “show interface” IOS command to extract speed and duplex from each interface.

Write Your Own Apps

o Define data positions on the map

Use the map to display the desired device and interface data.

Write Your Own Apps

o Define alarm thresholds

Indicate a threshold condition and associated warning message when threshold is exceeded.
