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
