Cisco Systems 3825 manual Creating a Class Map, Creating a Policy Map

Chapter 4 Configuring the Cisco 3825 Mobile Wireless Edge Router in a RAN-O Solution with the Command-Line

Configuration Sequence

Creating a Class Map

For each class map that you want to create, follow these steps, while in global configuration mode:

Step 1 Assign a name to your class map.

Router(config)# class-map [match-all match-any]class_name

Where match-anymeans that a single match rule is sufficient for class membership and match-allmeans that only packets that have all the specified attributes are part of the class.

For example, the following command specifies the class map as an llq-class:

Router(config)# class-map match-any llq-class

When you enter the class-mapcommand, you are in the class map configuration mode.

Step 2 To identify a specific IP differentiated service code point (DSCP) value as a match criterion, use the following command:

Router(config-cmap)# match ip dscp value

Where match ip dscp value specifies the exact value from 0 to 63 used to identify an IP DSCP value. For example, the following command specifies cs2 to be used as a match criterion:

Router(config-cmap)# match ip dscp cs2

For more information about this command, see the Cisco IOS Quality of Service Solutions Command Reference for your Cisco IOS Release.

Step 3 Exit the class map configuration mode.

Router(config-cmap)# exit

Creating a Policy Map

To create a policy map, follow these steps, while in the global configuration mode:

Step 1 Assign a name to your policy map.

Router(config)# policy-mappolicy_name

Where policy_name specifies the name of the traffic policy. The traffic policy may contain one or more traffic classes.

For example, the following command specifies the policy map of low latency queueing (LLQ).

Router(config)# policy-map llq-policy

When you enter the policy-mapcommand, you are in the policy map configuration mode. Step 2 Associate the llq-policy with a class map.

Router(config-pmap)# class class_name

Where class_name specifies the name of a traffic class you want to modify.

Specify the same class_name as you did in Step 1in the “Creating a Class Map” section on page 4-47.
