I was using netflow v5 (free) with my 857 router which managed 2 interfaces: bvi1 and vlan 1.

When we got a new ISP, I replaced the 857 with an Cisco 877 and upgraded to netflow V7.

It now monitors BVI1; Dialer0 and Virtual Interface2.

BVI1 logs both in and out traffic

Dialer0 does only in

Virtual Interface does only out

Due to budget and license constraints I only want to monitor 2 interfaces, like I always have, BVI1 and Dialer0.

I anticipate a problem when the “trial” expires for the virtual interface.

How can this be resolved?

Both Interfaces have "ip cef" and "ip route-cache flow"
