Notes: 1. You can configure up to 16 rules per Class Map. You can also include
multiple classes in a Policy Map.
2. You should create a Class Map (page 32-2) before creating a Policy Map
(page 32-4). Otherwise, you will not be able to specify a Class Map with the
class command (page 32-5) 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: 1-32 characters)
Default Setting
None
Command Mode
Global Configuration
Command Usage
• First enter this command to designate a class map and enter the Class Map
configuration mode. Then use the match command (page 32-3) to specify the
criteria for ingress traffic that will be classified under this class map.
• Only one match command is permitted per class map, so the match-any field
refers to the criteria specified by the lone match command for a class map.
• The class map uses the Access Control List filtering engine, so you must also
set an ACL mask to enable filtering for the criteria specified in the match
command. See “mask (IP ACL)” on page 23-6 or “mask (MAC ACL)” on
page 23-15 for information on configuring an appropriate ACL mask.
• The class map is used with a policy map (page 32-4) to create a service policy
(page 32-7) 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:
