Chapter 39 Configuring MPLS QoS Configuring MPLS 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. MPLS QoS does not attempt to apply commands from more than one policy map class to matched traffic. Configuring a Policy Map to Set the EXP Value on All Imposed Labels To set the value of the MPLS EXP field on all imposed label entries, use the set mpls experimental imposition command in QoS policy-map class configuration mode. To disable the setting, use the no form of this command. Note The set mpls experimental imposition command replaces the set mpls experimental command. Step 1 Step 2 Step 3 Step 4 Command Router(config)# policy-map policy_name Router(config-pmap)# class-map name [match-all | match-any] Router(config-pmap-c)# set mpls experimental imposition {mpls-exp-value | from-field [table table-map-name]} Router(config-pmap-c)# exit Purpose Creates a policy map. Accesses the QoS class-map configuration mode to configure QoS class maps. Sets the value of the MPLS experimental (EXP) field on all imposed label entries. Exits class-map configuration mode. The following example sets the MPLS EXP imposition value according to the DSCP value defined in the MPLS EXP value 3: Router# configure terminal Enter configuration commands, one per line.
