Setting dot1p Priorities for Incoming Traffic

Change the priority of incoming traffic on the interface using the dot1p-priority command from INTERFACE mode. The Dell Networking OS places traffic marked with a priority in a queue based on the following table.

If you set a dot1p priority for a port-channel, all port-channel members are configured with the same value. You cannot assign a dot1p value to an individual interface in a port-channel.

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) .
