(Optional) Configuring an Interface Priority
Context
An interface's priority is used in the following scenarios:
If the interface receives untagged packets, the device provides differentiated services for the packets based on the interface priority.
If the priority mapping function is disabled on the VLAN using the trust upstream none command, packets received on the VLAN can only be forwarded through priority mapping. In this case, the device provides differentiated services for the packets based on the interface priority.
