Quality of Service Commands 4

any traffic that exceeds the specified rate, or just reduce the DSCP service level for traffic exceeding the specified rate.

7.Use the service-policy command to assign a policy map to a specific interface.

Notes: 1. You can only configure one rule per Class Map. However, you can include multiple classes in a Policy Map.

2.You must create a Class Map before creating a Policy Map.

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 4-220)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 4-94or “mask (MAC ACL)” on page 4-102for information on configuring an appropriate ACL mask.

The class map is used with a policy map (page 4-221)to create a service policy (page 4-224)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:

Console(config)#class-map rd_class match-any

Console(config-cmap)#match ip dscp 3

Console(config-cmap)#exit

Console(config)#access-list ip mask-precedence in

Console(config-ip-mask-acl)#mask any any dscp

Console(config-ip-mask-acl)#
