multiple classes in a Policy Map.

You should create a Class Map (page 56-2) before creating a Policy Map
(page 56-4). Otherwise, you will not be able to specify a Class Map with the
class command (page 56-4) after entering Policy-Map Configuration mode.
class-map
This command creates a class map used for matching packets to the specified
class, and enters Class Map configuration mode. Use the
no form to delete a class
map and return to Global configuration mode.
Syntax
[ no ] class-map class-map-name [ match-any ]
• match-any - Match any condition within a class map.
• class-map-name - Name of the class map. (Range: 1-16 characters)

Command Usage
• First enter this command to designate a class map and enter the Class Map
configuration mode. Then use the match command (page 56-3) to specify the
criteria for ingress traffic that will be classified under this class map.
• Up to 16 match commands are permitted per class map.
• The class map is used with a policy map (page 56-4) to create a service policy
(page 56-7) for a specific interface that 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:
