How to enable Netflow on Nexus 7k

Hi,

I'm configuring the Assurance in Prime Infrasctructure 2.0 and would like to know how to configure NetFlow to export TCP and UDP traffic on Nexus 7k.

In the PI user guide 2.0 document there's no reference for nexus 7000.

Thanks Patricia Oliveira

Here is an example netflow configuration.

Basically, you need to use a flow record, flow exporter, and flow monitor.

flow exporter test

  destination 10.1.1.1

  transport udp 50001

  source Vlan1

  version 9

flow monitor Netflow

  record netflow-original

  exporter test

In this case the monitor uses the pre-configured template flow record which is "netflow-original'.  You can see the template for this record by looking at the output from "show flow record".

Below are the Configuration Guide and Command References for Netflow on Nexus.
