A CONFIGURATION mode service-class dynamic dot1p entry supersedes anyINTERFACE 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 thesame interface.• Honor dot1p priorities on ingress traffic.INTERFACE modeservice-class dynamic dot1pExample of Configuring an Interface to Honor dot1p Priorities on Ingress TrafficDell#config tDell(conf)#interface tengigabitethernet 1/2Dell(conf-if)#service-class dynamic dot1pDell(conf-if)#endDell#Priority-Tagged Frames on the Default VLANVLAN 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 configureservice-class dynamic dot1p or trust dot1p.When priority-tagged frames ingress an untagged port or hybrid port, the frames are classified to the defaultVLAN of the port and to a queue according to their dot1p priority if you configure service-class dynamicQuality of Service (QoS) 908
