Hello, What happen to the boundary when you have something like:
Switchport access vlan xx
Switchport voice Vlan dot1p
Switchport priority extend cos 4
MLS QOS trust COS
Now, I am extending the priority to the IP phone (Rewrite cos to a value of 4) but at the end, I state that I want the QOS to be trusted....
Unless the MLS QOS TRUST COS is intended to act on the COS of the phone only? But then I would have to specify "MLS QOS TRUST device Cisco-phone" or it would be applied to all traffic (PC and phone)??
Thanks a lot for any clarification
