Configuring QoS Class of Service Configuration Step 4 Step 5 Step 6 Step 7 Step 8 qos port-priority {dot1p-priority} Specify the port to 802.1p priority mapping for the desired port. The ingress packets from one port are first mapped to 802.1p priority based on the port to 802.1p mapping, then to TC queues based on the 802.1p to queue mapping. The untagged packets from one port will be added an 802.1p priority value according to the port to 802.1p mapping. dot1p-priority: Specify the 802.1p priority ranging from 0 to 7. The default value is 0. show qos trust interface [fastEthernet port | gigabitEthernet port | ten-gigabitEthernet port | port-channel port-channel-id] Verify the trust mode of the ports. show qos port-priority interface [fastEthernet port | gigabitEthernet port | tengigabitEthernet port | port-channel port-channel-id] Verify the port to 802.1p mappings. end Return to privileged EXEC mode. copy running-config startup-config Save the settings in the configuration file. ■■ Configuring the 802.1p to Queue Mapping Follow these steps to configure the 802.1p to queue mapping: Step 1 configure Enter global configuration mode Step 2 qos cos-map {dot1p-priority} {tc-queue} Specify the 802.1p to queue mapping. The packets with the desired 802.1p priority will be put in the corresponding queues. By default, the 802.1p priority 0 to 7 is respectively mapped to TC-1, TC-0, TC-2, TC-3, TC-4, TC-5, TC-6, TC-7. dot1p-priority: Specify the 802.1p priority. The valid values are from 0 to 7. tc-queue: Specify the ID number of the TC queue. The valid values are from 0 to 7. Step 3 show qos cos-map Verify the 802.1p to queue mappings. Step 4 end Return to privileged EXEC mode. Step 5 copy running-config startup-config Save the settings in the configuration file. User Guide 528
