[c-nsp] MPLS exp imposition on 7600

[Arie Vayner (avayner)]

John,

How is that VLAN connected to the customer? Over a trunk?
You should have the "mls qos vlan-based" command on the physical connection...

Hi.

I seem to be going mad. This is supposed to work, right? I'm trying to
get a policy-map to mark EXP5 for all traffic coming from a vlan.

mls qos
policy-map TEST
 class class-default
   set mpls exp impo 5
int vlan123
 descr to-CE
 service-policy input TEST

The counters aren't increasing:
PE#show policy-map interface

Vlan123

 Service-policy input: TEST

   class-map: class-default (match-any)
     Match: any
     set mpls experimental 5:
     Earl in slot 5 :
       0 bytes
       30 second offered rate 0 bps
       aggregate-forwarded 0 bytes


And a traceroute from the CE through PE shows that EXP is 0 for every
hop. And yes, this is where the traffic goes.

Setting the policy-map in the outgoing direction does increase the
counters, but that doesn't help much.

I also tried a policer with conform-action set mpls exp transmit, same results.

No trust (cos or dscp) configured anywhere. "mls qos mpls trust
experimental" is on by default and not disabled.

What could be wrong?
