Configuration example
z Configure to trust port priority on Ethernet 1/0/1 and set the priority of Ethernet 1/0/1 to 7.
Configuration procedure:
<Sysname> system-view
[Sysname] interface Ethernet1/0/1
[Sysname-Ethernet1/0/1] priority 7

[Sysname-Ethernet1/0/2] priority trust
Configuring the Mapping between 802.1p Priority and Local Precedence
When the default mapping between 802.1p priority and local precedence cannot satisfy your
requirements, you can modify the mapping at the CLI, thus modifying the mapping between 802.1p
priority and the output queues and assigning packets with different priorities to the corresponding output
queues.
Note that, this is a global setting, not a per port setting. This is only recommended for advanced network
environments.
Configuration prerequisites
The mapping between 802.1p priority and local precedence has been determined.
