Solved: Netflow on IRB

josepho · ‎10-22-2009

Hello Chaps,

I need to run neflow to capture the traffic through a router. This router also needs to be configured as a bridge (using IRB). I did the configs but when I use th "show ip flow export", I see that, no export is happening.

Can u help me with the direction to a document or procedure perform this task?

Thanks

You need:

ip route-cache flow

under BVI, not F.E.

On which interface you configured the command ?

Can we see your config? Particularly the part that shows the interface configuration for netflow?
