Re: Granular QoS on Vlan over MPLS Pseudowires

Hi Tony

Thanks for the prompt feedback.Unfortunately the CE is not a Switch,its a
normal cisco router.

Below is the schematic representation of the setup.

PE router ----expecting EF/AF4x/AF3x---------TX PE router------Vlan L2
Pseudo-wire with blanket DSCP marking-------TX
CE--------Customer-CE------Customer Qos Markings

The challenge at the moment as explained earlier is once I hand over the
traffic to the TX network,the TX Pseudo-wire does not see my QoS markings
from the CE and treats all my traffic with generic QoS marking until it
reaches the other end

I have engaged the provider to seek clarity and the explanation I get is
that its a limitation on the Tellabs equipment they are using.

Im aware that some Vendors have a solution to the problem that Im having.
I also have questions for the group that I need clarity on
1) is this doable on Cisco Pseudo-wires
2) if possible,is there some documentation I can look at to guide me in the
right direction.

regards
