Command Usage
◆ First enter this command to designate a class map and enter the Class Map
configuration mode. Then use match commands to specify the criteria for
ingress traffic that will be classified under this class map.
◆ One or more class maps can be assigned to a policy map (page 627). The policy
map is then bound by a service policy to an interface (page 638). A service
policy defines packet classification, service tagging, and bandwidth policing.
Example
This example creates a class map call “rd-class,” and sets it to match packets marked
for DSCP service value 3:
Console(config)#class-map rd-class match-any
Console(config-cmap)#match ip dscp 3
Console(config-cmap)#
