◆
One or more class maps can be assigned to a policy map ( page 531 ). The policy
map is then bound by a service policy to an interface ( page 541 ). A service
policy defines packet classification, service tagging, and bandwidth policing.
Once a policy map has been bound to an interface, no additional class maps
may be added to the policy map, nor any changes made to the assigned class
maps with the
match or set commands.
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)#
