So I just setup a new point to point layer 2 service to handle our replication traffic. This is layer 2 service but am routing over the link. The way this is done with Cisco L3 switches is you have to turn the interface connected to layer 3 interface by issuing no switchport then assigning an IP. The reason I bring this up is that all our other interfaces we are monitoring are layer 2 interfaces.
The problem is that on this layer 3 interface It says there is zero traffic but when I click into the interface and get to Netflow I see a ton of traffic. Is there something I have to do to get it report the bandwidth being used at the interface level?
Config on switch interface is below:
description cogent p2p to dc
ip flow monitor NETFLOW-MON-IN input
ip flow monitor NETFLOW-MON-OUT output
ip address 172.16.255.1 255.255.255.252
