Chapter Cisco MWR 2941 Router Command Reference, Release 15.1(3)MR

policy-map

Usage Guidelines Use the policy-map command to specify the name of the policy map to be created, added to, or modified

before you configure policies for classes whose match criteria are defined in a class map. The

policy-map command enters policy-map configuration mode, in which you can configure or modify the

class policies for a policy map.

You can configure class policies in a policy map only if the classes have match criteria defined for them.

Use the class-map and match commands to configure the match criteria for a class. Because you can

configure a maximum of 64 class maps, a policy map cannot contain more than 64 class policies.

A single policy map can be attached to more than one interface concurrently. Except as noted, when you

attempt to attach a policy map to an interface, the attempt is denied if the available bandwidth on the

interface cannot accommodate the total bandwidth requested by class policies that make up the policy

map. In this case, if the policy map is already attached to other interfaces, it is removed from them.

Whenever you modify class policy in an attached policy map, class-based weighted fair queueing

(CBWFQ) is notified and the new classes are installed as part of the policy map in the CBWFQ system.

Note Policy-map installation via subscriber-profile is not supported. If you configure an unsupported policy

map and there are a large number of sessions, then an equally large number of messages print on the

console. For example, if there are 32,000 sessions, then 32,000 messages print on the console at 9,600

baud.

Examples The following example creates a policy map called “policy1” and configures two class policies included

in that policy map. The class policy called “class1” specifies policy for traffic that matches access

control list (ACL) 136. The second class is the default class to which packets that do not satisfy

configured match criteria are directed.

! The following commands create class-map class1 and define its match criteria:

class-map class1

match access-group 136

! The following commands create the policy map, which is defined to contain policy

! specification for class1 and the default class:

policy-map policy1

class class1
