You can configure the DSCP to IEEE 802.1p mapping to allow the Switch to 
prioritize all traffic based on the incoming DSCP value according to the DiffServ to 
IEEE 802.1p mapping table. 

The following table shows the default DSCP-to-IEEE802.1p mapping.

DSCP

Use this section to specify the DSCP values that you want to assign to packets 
based on the color they are marked via TRTCM.

you are done configuring.
