— 

Configure to trust port 
priority and configure the 
port priority 

priority priority-level 

Optional 

By default, the switch trusts 
port priority and the priority 
of a port is 0.  

 

Follow these steps to configure to trust packet priority: 

Enter system view 

— 

Enter Ethernet port view 

interface interface-type

— 

Configure to trust packet 
priority 

Required 

By default, the switch trusts 
port priority.  

 

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 

z 

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 

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. 

The mapping between 802.1p priority and local precedence has been determined.
