I know this is an old topic but despite all my readings on the PFC QoS etc. etc. I cannot find a solution.
Perhaps you guys can assist.
We using ESM20G(2x10G's) cards for the core-facing llinks. We have ME (C7600, ME34/36/38) access network.
This is our requirement:
when we receive (in-profile) labeled packets on the egress PE from the P, we need the EXP values to be used for classification in our egress LLQ pmap on the outgoing interface (me-access-facing interface)
[i can see from the show output that the ES card is "supposed" to be in Pipe Mode]
c7606x01m#sh mls qos module 3
QoS is enabled globally
Policy marking depends on port_trust
QoS ip packet dscp rewrite disabled on slots: 1,2,3,4,5,6
QoS ip packet dscp rewrite enabled on slots: None
QoS serial policing mode disabled globally
Input mode for GRE Tunnel is Pipe mode
Input mode for MPLS is Pipe mode
Vlan or Portchannel(Multi-Earl) policies supported: Yes
Egress policies supported: Yes
Police acl redirected packets enabled: No
Marking statistics enabled: Yes
we also need to have the incoming EXP bit values copied into the CoS values of the egress traffic leaving the the me-access-facing interface.
[we have tried the trust cos, dscp and no mls trust options on the core-facing interface but we still seeing the customer traffic as only CoS 0 traffic leaving the me-access-facing ring.
