Priority mapping configuration tasks
You can configure priority mapping by using any of the following methods:
• Configuring priority trust mode—In this method, you can configure a port to look up a trusted
priority type (802.1p, for example) in incoming packets in the priority maps. Then, the system maps
the trusted priority to the target priority types and values.
• Changing port priority—If no packet priority is trusted, the port priority of the incoming port is used.
By changing the port priority of a port, you change the priority of the incoming packets on the port.
To configure priority mapping, perform the following tasks:
