dot1p Queue Number
7 3
• Change the priority of incoming traffic on the interface.
dot1p-priority
Example of Configuring a dot1p Priority on an Interface
NOTE: The dot1p-priority command marks all incoming traffic on an interface with a specified
dot1p priority and maps all incoming traffic to the corresponding queue. When you enable PFC
and/or ETS on an interface, incoming traffic with a specified dot1p priority can be distributed across
different queues. Therefore, when you use PFC and ETS to manage data center traffic, it is not
recommended that you use the dot1p-priority command to set a queue assignment. For more
information, refer to Data Center Bridging (DCB).

Honoring dot1p Priorities on Ingress Traffic
By default, the Dell Networking OS 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.
