Understanding QoS "Show Queueing interface X/X" command 6500

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:

Hi GREGORY JACKSON,

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.
