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

You cannot configure service-policy input and service-class dynamic dot1p on the

same interface.

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
