Netflow not working on Multilink interface

Hi Guys,

I have a Cisco 2821 with two serial interfaces bundled using PPP multilink. I want to monitor traffic flow (net flow) on the multilink interface. I have tried configuring ip route-cache flow/ ip flow ingress / egress but no luck.

The other thing is when I do sh ip cache flow I guess I should see the multilink interface in both Source and destination columns which is not happening (not showing in destination column).

The other router with same config but with ATM sub-interface working properly (same IOS).

Are there any hits on this ? Also, is it possible to use SPAN feature ? The monitoring server is at some other site (coming via WAN).

Best regards,

Santosh

Perhaps you could post the config and that might help us to give better advice on this question.
