Problems with configuring netflow

Unanswered Question

I'm trying to setup up netflow to export to a collection server, but I don't see any traffic coming from the router in question to the collection server, nor do I see the flow information on the router itself when i use show ip flow cache. Any ideas on what I might be doing wrong? I'm using the defaults for this initial configuration.

I have this problem too.

What kind of device?

What is the actual config on the device?

set the following:

on interfaces serial0/0/0, GigabitEthernet0/0, GigabitEthernet0/1 set: ip flow ingress

or ip flow route-cache

I think that it helps. Set also flow export timers: ip flow-cache timeout active + inactive

I recommend set inactive to 30 sec and active to 1-3 minute...

Kind regards,
