Chapter 38 Configuring PFC QoS Configuring PFC QoS 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 38-61 • Policy Map Class Configuration Guidelines and Restrictions, page 38-61 • Creating a Policy Map Class and Configuring Filtering, page 38-61 • Configuring Policy Map Class Actions, page 38-62 Creating a Policy Map To create a policy map, perform this task: Command Router(config)# policy-map policy_name Router(config)# no policy-map policy_name Purpose Creates a policy map. Deletes the policy map. Policy Map Class Configuration Guidelines and Restrictions When you configuring policy map classes, follow the guidelines and restrictions: • 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. • 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. Creating a Policy Map Class and Configuring Filtering To create a policy map class and configure it to filter with a class map, perform this task: Command Router(config-pmap)# class class_name Router(config-pmap)# no class class_name Purpose Creates a policy map class and configures it to filter with a class map. Note PFC QoS supports class maps that contain a single match command. Clears use of the class map.
