This example shows how to classify traffic by matching packets based on the DSCP value in the DiffServ
field of the IP header:
switch# configure terminal
switch(config)# class-map type qos class_dscp
switch(config-cmap-qos)# match
Use the show class-map command to display the DSCP class-map configuration:
