New Cisco router only showing traffic in one direction for Netflow

Router type:  Cisco 3825

Cisco IOS v15.0 will send flexible netflow

Solution

Here are the command lines that are needed.

The issue may occur if Cisco Express Forwarding Switching is disabled with the command:

no ip route-cache cef

To resolve the issue, enable CEF under the router's primary Ethernet interface.  Having CEF disabled may interfere with proper flexible netflow operation.

For more information see:

How to verify Cisco Express Forwarding Switching

 

Environment

 Cisco IOS v15.0 will send flexible netflow to Cascade Gateway.
