Usage Guidelines for the class-map Command

Use the class-map command to create or modify class map match criteria. The router compares the
packets that arrive at the input or output interface to the match criteria configured for a class map. If a
packet matches the criteria, the router designates the packet as belonging to the class.
When you configure a class map, you can use one or more match commands to specify the match
criteria. For example, you can configure the match access-group command, the match protocol
command, and the match input-interface command in a class map. The router compares the arriving
packets to the match criteria in the order in which you entered the criteria.

qos match statistics Command

To configure the router to count QoS matches for each class or for each match statement and class, use
the qos match statistics command in global configuration mode.
