Configuring Standard QoS Chapter 28 Configuring QoS Command Purpose Step 8 exit Return to policy map configuration mode. Step 9 exit Return to global configuration mode. Step 10 interface interface-id Specify the port to attach to the policy map, and enter interface configuration mode. Valid interfaces include physical ports. Step 11 service-policy input policy-map-name Specify the policy-map name, and apply it to an ingress port. Only one policy map per ingress port is supported. Step 12 end Return to privileged EXEC mode. Step 13 show policy-map [policy-map-name [class Verify your entries. class-map-name]] Step 14 copy running-config startup-config (Optional) Save your entries in the configuration file. To delete an existing policy map, use the no policy-map policy-map-name global configuration command. To delete an existing class map, use the no class class-map-name policy-map configuration command. To return to the untrusted state, use the no trust policy-map configuration command. To remove an assigned DSCP or IP precedence value, use the no set {ip dscp new-dscp | ip precedence new-precedence} policy-map configuration command. To remove an existing policer, use the no police rate-bps burst-byte [exceed-action {drop | policed-dscp-transmit}] policy-map configuration command. To remove the policy map and port association, use the no service-policy input policy-map-name interface configuration command. This example shows how to create a policy map and attach it to an ingress port. In the configuration, the IP standard ACL permits traffic from network 10.1.0.0. For traffic matching this classification, the DSCP value in the incoming packet is trusted. If the matched traffic exceeds an average traffic rate of 48000 bps and a normal burst size of 8000 bytes, its DSCP is marked down (based on the policed-DSCP map) and sent: Switch(config)# access-list 1 permit 10.1.0.0 0.0.255.255 Switch(config)# class-map ipclass1 Switch(config-cmap)# match access-group 1 Switch(config-cmap)# exit Switch(config)# policy-map flow1t Switch(config-pmap)# class ipclass1 Switch(config-pmap-c)# trust dscp Switch(config-pmap-c)# police 48000 8000 exceed-action policed-dscp-transmit Switch(config-pmap-c)# exit Switch(config-pmap)# exit Switch(config)# interface gigabitethernet0/1 Switch(config-if)# service-policy input flow1t This example shows how to create a Layer 2 MAC ACL with two permit statements and attach it to an ingress port. The first permit statement allows traffic from the host with MAC address 0001.0000.0001 destined for the host with MAC address 0002.0000.0001. The second permit statement allows only Ethertype XNS-IDP traffic from the host with MAC address 0001.0000.0002 destined for the host with MAC address 0002.0000.0002.
