Command History
Usage Guidelines The match cos command specifies a CoS value to use as the match criteria to determine if packets belong
to the class specified by the class map.
Before using the match cos command, you must enter the class-map global configuration command to
specify the name of the class whose match criteria you want to establish.
Matching of CoS values is supported only on ports carrying Layer 2 VLAN-tagged traffic. That is, you
can use the cos classification only on IEEE 802.1Q trunk ports.
You can use match cos classification in input and output policy maps.
Examples This example shows how to create a class map called inclass, which matches all the incoming traffic with
CoS values of 1 and 4:
Switch(config)# class-map match-any in-class
Switch(config-cmap)# match cos 1 4
Switch(config-cmap)# exit
You can verify your settings by entering the show class-map privileged EXEC command.
