[c-nsp] xconnect problem between C7606

Wed Oct 15 11:00:39 EDT 2014

I've had this issue with two LAN cards on a 7600 before with a
bog-standard EoMPLS circuit (with a slightly raised MTU from the default
1500).  In that case the microcode was "eating" (seemingly at random) some
MPLS packets from the customer who was purchasing the circuit, that caused
packet loss on the circuit and slow throughput.

It was solved by placing a service-policy on the interface on both sides
(ingress only) that did nothing (set dscp to dscp), somehow putting the
policy in place fixed things with no explanation provided.

Kind regards
Sibbi
