Priority mapping configuration tasks

You can modify priority mappings by modifying priority mapping tables, priority trust mode on a port,

and port priority.

To configure priority mapping, perform the following tasks:

Tasks at a

(Optional.) Configuring a priority map

(Required.) Perform one of the following tasks:

• Configuring a port to trust packet priority for priority mapping

• Changing the port priority of an interface

Configuring a priority map

This feature is available on both Layer 2 and Layer 3 Ethernet interfaces. The term "interface" in this

section collectively refers to these two types of interfaces. You can use the port link-mode command to
