You cannot configure port-based and policy-based QoS on the same interface.

Port-Based QoS Configurations

You can configure the following QoS features on an interface.

• 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.
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.
