Great! This is the command I was looking for.. I do have another question though. I'm testing a mVPN. It uses the multicast tunnel (mt) interfaces for the traffic. When I do a 'monitor interface traffic' I only see packets on the receiving end of the tunnel hitting the MT interface. My question is, I assume there is a performance limitation associated with the MT interface. When I do a 'show interface' it states that this interface is 800Mbps capable, so I assume this is the max aggregate traffic that this PIC can service? Is there a command I can use to view the overall utilization of the PIC?
