This example shows how to classify traffic by matching packets based on the precedence value in the ToS
byte field of the IP header:
switch# configure terminal
switch(config)# class-map type qos class_precedence
switch(config-cmap-qos)# match precedence 1-2, critical
Use the show class-map command to display the IP precedence value class-map configuration:
switch# show class-map class_precedence
