Hi there

I have a question about the QoS port configuration for the AAP1 in question 2.8.

The port is configured as a trunk, so normally you would trust COS.

int fa0/2
 mls qos trust cos
!

But there we have to apply a service policy, where DSCP is trusted:

policy-map policy-trust-voice
 class class-rtp
  trust DSCP
 class class-sccp
  trust DSCP
!
int fa0/2
 service-policy input policy-trust-voice
!

We is it DSCP and not COS anymore?

Regards
Dominic
