Use the policy-map command to specify the name of the policy map,

and then use the

class

command to configure policies for traffic that

matches the criteria defined in a class map.

A policy map can contain multiple class statements that can be applied

to the same interface with the

service-policy

command.

Create a Class Map (

page 835

) before assigning it to a Policy Map.

E

XAMPLE

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

flow

command to limit the average bandwidth to 100,000 Kbps, the burst

rate to 4000 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 cos 0

Console(config-pmap-c)#police flow 10000 4000 conform-action transmit

violate-action drop

Console(config-pmap-c)#

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.

Policy Map Configuration

SAGE

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 command and

one of the police commands to specify the match criteria, where the:

set phb

command sets the per-hop behavior value in matching

packets. (This modifies packet priority for internal processing only.)

set cos

command sets the class of service value in matching

packets. (This modifies packet priority in the VLAN tag.)
