***Note - check your Cisco IOS device to see if sending Netflow is supported. I was surprised to find that some Cisco layer 3 switching platforms don't currently support Netflow. An example is the Catalyst 3560.

In Global configuration mode:

1. Type "ip flow-export destination ipaddress port" and press enter.
   ipaddress is the IP address of your Netflow Collector. port is the port your Netflow Collector listens on.
2. Type "ip flow-export source interface" and press enter. interface is the interface/s you want to get statistics on.
3. Type "ip flow-export version versionnumber" and press enter. versionnumber is the version of Netflow your Netflow Collector supports.

Under the interfaces you want to get statistics on:

1. Type "ip route-cache flow" and press enter.

This configuration is specific to non-MLS devices. There will be an MLS specific Netflow HowTo shortly. :)
