Re: Granular QoS on Vlan over MPLS Pseudowires

Is the CE device a switch facing the PE?

How many vlans are permitted in the trunk?

When marking I'd normally trust on dscp and let the switch use the default mutation map to convert dscp>cos bits in the dot1q tag I.e 4 for Video and 5 for Voice

But it's down to the provider to offer the end-to-end service where they should offer to match the cos bits into MPLS groups on the relevant pseudowire policy-maps where the cos bits are copied into the MPLS shim headers in a pipe design..

The bandwidth would be policed inbound on the PE facing the CE for conformance

The provider may further have MPLE TE tunnels for the pseudowires and depending on how many sites you wanted the traffic to reach I.e rooted P2M design (hub and spoke in L3 terms)
