Netflow Configuration on Cisco 887

Hi,

I am trying to configure netwflow monitoring on a Cisco 887 router. I want to be able to report on the traffic that passes through the Dialer1 interface.

So far I can only see traffic that goes OUT of the Dialer1 interface, I can't see traffic that goes IN. I'm not sure why I can't see Inbound traffic.

Current Netflow Configuration on 887;

interface Dialer1

bandwidth 24576

ip unnumbered Loopback0

no ip redirects

no ip unreachables

no ip proxy-arp

ip flow ingress

ip flow egress

encapsulation ppp

no ip route-cache cef

dialer pool 1

ppp authentication chap callin

ppp chap hostname xxxxxxxxxxxxxx

ppp chap password 7 xxxxxxxxxxxxx

no cdp enable

!

hold-queue 224 in

end

!

ip flow-cache timeout active 1

ip flow-export source Loopback0

ip flow-export version 5

ip flow-export destination 10.10.70.11 9996

Output of 'sh ip flow int'

Dialer1

  ip route-cache flow

  ip flow ingress

  ip flow egress

Does anyone know why I can't see the IN traffic for interface Dialer1?

Thanks,

Paul

Previously I found that I needed to have cef enabled for flows to come through on our Cisco 877's.

Hi Scott,

That did it. I enabled 'ip route-cache cef' and started to see IN traffic for the interface.

Thanks for you help,

Paul
