Configuring QoS Chapter 27 Configuring QoS This example shows how to create policy map with a conform action of set dscp and a default exceed action, and attach it to an EFP. Switch(config)# class-map in-class-1 Switch(config-cmap)# match dscp 14 Switch(config-cmap)# exit Switch(config)# policy-map in-policy Switch(config-pmap)# class in-class-1 Switch(config-pmap-c)# police 230000 8000 conform-action set-dscp-transmit 33 exceed-action drop Switch(config-pmap-c)# exit Switch(config-pmap)# exit Switch(config)# interface gigabitethernet0/1 Switch (config-if)# service instance 1 Ethernet Switch (config-if-srv)# service-policy input in-policy Switch (config-if-srv)# exit This example shows how to use policy-map class police configuration mode to set multiple conform actions and an exceed action. The policy map sets a committed information rate of 23000 bits per second (b/s) and a conform burst size of 10000 bytes. The policy map includes multiple conform actions (for DSCP and for Layer 2 CoS) and an exceed action. Switch(config)# class-map cos-set-1 Switch(config-cmap)# match cos 3 Switch(config-cmap)# exit Switch(config)# policy-map map1 Switch(config-pmap)# class cos-set-1 Switch(config-pmap-c)# police cir 23000 bc 10000 Switch(config-pmap-c-police)# conform-action set-dscp-transmit 48 Switch(config-pmap-c-police)# conform-action set-cos-transmit 5 Switch(config-pmap-c-police)# exceed-action drop Switch(config-pmap-c-police)# exit Switch(config-pmap)# exit Switch(config)# interface gigabitethernet0/1 Switch(config-if)# service-policy input map1 Switch(config-if)# exit Configuring a Policy Map with 2-Rate, 3-Color Policing A 2-rate, 3-color policer uses both the committed information rate (CIR) and the peak information rate (PIR) and includes three profiles (colors) for packets that conform, exceed, or violate the specified rates. You can configure actions to take on each of these profiles. Beginning in privileged EXEC mode, follow these steps to create an input policy map with individual 2-rate, 3-color policing: Step 1 Step 2 Command configure terminal class {class-map-name | class-default} Step 3 policy-map policy-map-name Purpose Enter global configuration mode. Enter a class-map name or class-default to match all unclassified packets, and enter policy-map class configuration mode. If you enter a class-map name, you must have already created the class map by using the class-map global configuration command. Create a policy map by entering the policy map name, and enter policy-map configuration mode. By default, no class maps are defined. 27-38 Cisco ME 3800X and 3600X Switch Software Configuration Guide OL-23400-01
