Description (partial)

A Cisco 7600 router running IOS version 12.2(33)SRD3 using VPLS using EVC-style configuration may stop forwarding traffic in and out of some attachment circuits on a line-card.  In this case the service instance appears to be operational from the RSP - however traffic statistics indicate that no traffic is passing.  

Impact of the issue is that no traffic passes in or out of the EFP.   

This issue can occur if exceeding the number of EFPs supported on the chassis which is 16,000 when utilising port-channels as opposed to 32,000 when using only physical ports.
