Priority mapping configuration tasks
You can configure priority mapping in two approaches:
Configuring priority trust mode. In this approach, you can configure a port to look
up a certain priority, 802.1p for example, in incoming packets, in the priority
mapping tables. If an incoming packet does not carry the trusted priority field or if
the port is configured not to trust any packet priority, the port priority of the
incoming port is used.
Changing port priority. By default, all ports are assigned the port priority of zero. By
changing the port priority of a port, you change the priority of the incoming
packets on the port.
Perform these optional tasks to configure priority mapping:
