6509 problems

Hi

Apologies if this is a repost but I�ve been unable to find anything which can help.

I have a number of 6509's which i would like to monitor with netflow.

I've configured one as a test (6509, sup720, ios ver: 12.2(17d)SXB5).

I am receiving the flows after making the following configuration:

ip flow-export version 5
ip flow-export destination X.X.X.X 9996

int vlan 1
ip flow ingress
ip route-cache flow

int vlan 2
ip flow ingress
ip route-cache flow

etc....

As i said i'm receiving the flows ok although netflow is only displaying statistics for out traffic, i.e. int vlan 2 in 3.23Kbs, out 32.32Mbs.

Any advice?
