Dell(conf)#interface gigabitethernet 1/1

Honoring dot1p Priorities on Ingress Trac
By default, Dell Networking OS does not honor dot1p priorities on ingress trac.
You can congure this feature on physical interfaces and port-channels, but you cannot congure it on individual interfaces in a port
channel.
You can congure service-class dynamic dot1p from CONFIGURATION mode, which applies the conguration 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 congure service-policy input and service-class dynamic dot1p on the same interface.
• Honor dot1p priorities on ingress trac.

Example of Conguring an Interface to Honor dot1p Priorities on Ingress Trac

Priority-Tagged Frames on the Default VLAN
Priority-tagged frames are 802.1Q tagged frames with VLAN ID 0. For VLAN classication, these packets are treated as untagged.
However, the dot1p value is still honored when you congure service-class dynamic dot1p or trust dot1p.
