[c-nsp] IEEE 802.1P QoS Issue........

[Scott Miller]

Does the edge have the appropriate service policy in an outbound direction
to you applied?

What is the CPE?

On most CPE's, I prefer to apply the outbound service policy to the
physical interface - it acts like a catch-all for all outgoing traffic.
 (personal preference I guess)

You can verify you are receiving tagged traffic with a simple access-list,
and apply it in an inbound direction on your WAN interface.

access-list 199 permit ip any any dscp af41 log
access-list 199 permit ip any any
access-list 198 permit ip any any dscp af41 log
access-list 198 permit ip any any

-OR-

access-list 199 permit ip any any dscp 46 log
access-list 199 permit ip any any
access-list 198 permit ip any any dscp 46 log
access-list 198 permit ip any any

The apply each one in a different direction:

int g0/2
ip access-group 199 in
ip access-group 198 out

then "show access-list"

If you are receiving tagged traffic, the "inbound" access-list (199) will
increment.  So make a normal voice call, and after (or during) check the
access-list for hits.  If you are tagging traffic properly from within your
network, the outbound access-list will also increment.

Hope this helps in any way.
