I'm trying insure that no PC traffic ever leaves the access layer with anything other than dscp/cos 0, so that some smart WinXP user can't mark his traffic like voice.
The access layer is a 6506 running IOS. I figure all I need to do is set up an ACL for all traffic on our data network space, run that through a policy map to mark the permitted traffic to 0, then apply the policy map to the vlan interface that the access layer PCs are plugged into.
Each port on the 6506 blades will have an Avaya IP phone and a PC plugged into the IP phone. The PC data network is 126.96.36.199 vlan 17 and the voice network is 172.26.0.0. vlan 910.
I have a utility I'm using that I can mark the PC (WinXP) packets to dscp=46 to simulate voice traffic.
Here is the pertinent config, and the problem is after spanning the port the PC is plugged into I still see it's packets marked with dscp=46.
Have I set up the correct way to mark all traffic from 188.8.131.52 to dscp=0, or is there another way to do this?

match access-group 161
