To do...
Enter system view
Enter Ethernet port view
Configure to trust packet
priority
Configuration example
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
Configure to trust packet priority on Ethernet 1/0/2.
Configuration procedure:
<Sysname> system-view
[Sysname] interface Ethernet1/0/2
[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
