Chapter 39 Configuring MPLS QoS Configuring MPLS QoS Configuring Named EXP Mutation Maps To configure a named EXP mutation map, perform this task: Command Step 1 Router(config)# mls qos map exp-mutation name mutated_exp1 mutated_exp2 mutated_exp3 mutated_exp4 mutated_exp5 mutated_exp6 mutated_exp7 mutated_exp8 Router(config)# no mls qos map exp-mutation name Step 2 Router(config)# end Step 3 Router# show mls qos maps Purpose Configures a named EXP mutation map. Reverts to the default map. Exits configuration mode. Verifies the configuration. When configuring a named EXP mutation map, note the following information: • You can enter up to eight input EXP values that map to a mutated EXP value. • You can enter multiple commands to map additional EXP values to a mutated EXP value. • You can enter a separate command for each mutated EXP value. • You can configure 15 ingress EXP mutation maps to mutate the internal EXP value before it is written as the ingress EXP value. You can attach ingress EXP mutation maps to any interface that PFC QoS supports. • PFC QoS derives the egress EXP value from the internal DSCP value. If you configure ingress EXP mutation, PFC QoS does not derive the ingress EXP value from the mutated EXP value. Attaching an Egress EXP Mutation Map to an Interface To attach an egress EXP mutation map to an interface, perform this task: Step 1 Step 2 Step 3 Step 4 Command Purpose Router(config)# interface {{vlan vlan_ID} | {type1 slot/port[.subinterface]} | {port-channel number[.subinterface]}} Selects the interface to configure. Router(config-if)# mls qos exp-mutation exp-mutation-table-name Attaches an egress EXP mutation map to the interface. Router(config-if)# no mls qos exp-mutation Removes the egress DSCP mutation map from the interface. Router(config-if)# end Exits configuration mode. Router# show running-config interface {{vlan vlan_ID} | {type slot/port} | {port-channel number}} Verifies the configuration. 1. type = ethernet, fastethernet, gigabitethernet, or tengigabitethernet This example shows how to attach the egress EXP mutation map named mutemap2: Router(config)# interface fastethernet 3/26 Router(config-if)# mls qos exp-mutation mutemap2 Router(config-if)# end OL-11439-03 Catalyst Supervisor Engine 32 PISA Cisco IOS Software Configuration Guide, Release 12.2ZY 39-29
