class

This command defines a traffic classification upon which a policy can act, and enters

Policy Map Class configuration mode. Use the no form to delete a class map and

return to Policy Map configuration mode.

Syntax

[no] class class-map-name

class-map-name - Name of the class map. (Range: 1-32 characters)

Default Setting

None

Command Mode

Policy Map Configuration

Command Usage

• Use the policy-map command to specify a policy map and enter Policy Map

configuration mode. Then use the class command to enter Policy Map Class

configuration mode. And finally, use the set and police commands to specify

the match criteria, where the:

- set command classifies the service that an IP packet will receive.

- police command defines the maximum throughput, burst rate, and the

action that results from a policy violation.

• Currently you may only configure one rule per Class Map, but you can assign

one or more classes to a policy map.

Example

This example creates a policy called “rd_policy,” uses the class command to specify

the previously defined “rd_class,” uses the set command to classify the service that

incoming packets will receive, and then uses the police command to limit the

average bandwidth to 100,000 Kbps, the burst rate to 1522 bytes, and configure the

response to drop any violating packets.

Console(config)#policy-map rd_policy

Console(config-pmap)#class rd_class

Console(config-pmap-c)#set ip dscp 3

Console(config-pmap-c)#police 100000 1522 exceed-action drop
