Chapter 42 Configuring PFC QoS

Configuring PFC QoS

This example shows how to verify the configuration:

Router# show class-map ipp5

Class Map match-all ipp5 (id 1)

Match ip precedence 5

Configuring a Policy Map

You can attach only one policy map to an interface. Policy maps can contain one or more policy map classes, each with different policy map commands.

Configure a separate policy map class in the policy map for each type of traffic that an interface receives. Put all commands for each type of traffic in the same policy map class. PFC QoS does not attempt to apply commands from more than one policy map class to matched traffic.

These sections describe policy map configuration:

•Creating a Policy Map, page 42-73

•Policy Map Class Configuration Guidelines and Restrictions, page 42-73

•Creating a Policy Map Class and Configuring Filtering, page 42-74

•Configuring Policy Map Class Actions, page 42-74

Creating a Policy Map

To create a policy map, perform this task:

Command

Purpose

 

 

Router(config)# policy-mappolicy_name

Creates a policy map.

Router(config)# no policy-mappolicy_name

Deletes the policy map.

 

 

Policy Map Class Configuration Guidelines and Restrictions

When you configuring policy map classes, follow the guidelines and restrictions:

•The PFC2 support the class class_name protocol policy map command, which configures NBAR and sends all traffic on the Layer 3 interface, both ingress and egress, to be processed in software on the MSFC2. To configure NBAR, refer to this publication:

http://www.cisco.com/univercd/cc/td/doc/product/software/ios122/122newft/122t/122t8/dtnbarad.htm

•PFC QoS does not support the class class_name destination-address, class class_name input-interface, class class_name qos-group, and class class_name source-addresspolicy map commands.

•With Release 12.2(18)SXE and later releases, PFC QoS supports the class default policy map command.

•PFC QoS does not detect the use of unsupported commands until you attach a policy map to an interface.
