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. PFCQoS 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

To create a policy map, perform this task:

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-address policy 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.
Command Purpose
Router(config)# policy-map policy_name Creates a policy map.
Router(config)# no policy-map policy_name Deletes the policy map.
