Packet Dot1p on Ingress Packet Queue Number on C9000 Series 3 3 4 4 5 5 6 6 7 7 • Change the priority of incoming traffic on the interface. dot1p-priority Example of Configuring a dot1p Priority on an Interface Dell#config Dell(conf)#interface tengigabitethernet 1/2 Dell(conf-if)#switchport Dell(conf-if)#dot1p-priority 1 Dell(conf-if)#end Dell# Honoring dot1p Priorities on Ingress Traffic By default, the system does not honor dot1p priorities on ingress traffic. You can configure this feature on physical interfaces and port-channels, but you cannot configure it on individual interfaces in a port channel. You can configure service-class dynamic dot1p from CONFIGURATION mode, which applies the configuration to all interfaces. A CONFIGURATION mode service-class dynamic dot1p entry supersedes any INTERFACE entries. For more information, refer to Mapping dot1p Values to Service Queues. NOTE: You cannot configure service-policy input and service-class dynamic dot1p on the same interface. • Honor dot1p priorities on ingress traffic. INTERFACE mode service-class dynamic dot1p Example of Configuring an Interface to Honor dot1p Priorities on Ingress Traffic Dell#config t Dell(conf)#interface tengigabitethernet 1/2 Dell(conf-if)#service-class dynamic dot1p Dell(conf-if)#end Dell# Priority-Tagged Frames on the Default VLAN VLAN Priority-tagged frames are 802.1Q tagged frames with (default) VLAN ID 0. For VLAN classification, these packets are treated as untagged. However, the dot1p value is still honored when you configure service-class dynamic dot1p or trust dot1p. When priority-tagged frames ingress an untagged port or hybrid port, the frames are classified to the default VLAN of the port and to a queue according to their dot1p priority if you configure service-class dynamic Quality of Service (QoS) 908
