Flexible NetFlow Configuration example for Performance Monitoring for TCP, VoIP and Cisco NBAR

July 12, 2012

Here is a sort of generalized FnF – Flexible NetFlow configuration where I created a TCP class that includes all TCP traffic. I don't normally recommend this as typically I would identify the business applications that I want to track with performance monitor and create classes for monitoring each. If all TCP latency is desired, this should work fine. Also, this FnF configuration is based on IOS 15.2(2)T and includes Cisco NBAR configuration details as well. If an earlier IOS is being used, ignore the error when creating the flow records. Reports should still work well if of course you have the best NetFlow reporting solution.
