Port-Based QoS Configurations
You can configure the following QoS features on an interface.
• Setting dot1p Priorities for Incoming Traffic
• Configuring Port-Based Rate Policing
• Configuring Port-Based Rate Shaping
Setting dot1p Priorities for Incoming Traffic
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
Dell#configure terminal
Dell(conf)#interface tengigabitethernet 1/1
Dell(conf-if-te-1/1)#switchport
Dell(conf-if-te-1/1)#dot1p-priority 1
Dell(conf-if-te-1/1)#end
Honoring dot1p Priorities on Ingress Traffic
By default, 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.
