Can i get some help to turn on net flows on my cisco router. I have T1 connection (s0/1/0) and FE port with different sub-interfaces. I want to monitor all my traffic going out the s0/1/0 (WAN) interface.

Thanks. My IOS does not support ip route-cache flow.

Can i use ip flow ingress and ip flow egress as a replacement for the route-cache flow command.

Also is F0/1 lan interface or the WAN interface.


Thanks,

Osman
