Hello -- I am trying to determine if my psckets are being marked withe correct DSCP value on a 6513 Sup2t. I have put all the output below. My primary question is the traffic coming from port 2/3/23 being marked with DSCP 46?
I am using MS Lync and the phone is Ploycom CX 600:

Extend trust state: not trusted [COS = 0]

Hi GREGORY JACKSON,
your QoS is disabled globally, to enable it:
mls qos mls qos map cos-dscp 0 8 16 24 34 46 48 56
You should try the following:
Interface GigabitEthernet2/3/23 mls qos cos 5
For more info about QoS in a 6500 Series, check this link: QoS 6500.
Hope this helps.
