z 

Configure to trust port priority on GigabitEthernet 1/0/1 and set the priority of GigabitEthernet 1/0/1 

to 7.  

Configuration procedure: 

<device> system-view 

[device] interface GigabitEthernet1/0/1 

[device-GigabitEthernet1/0/1] priority 7 

z 

Configure to trust 802.1p precedence on GigabitEthernet 1/0/1. 

Configuration procedure: 

<device> system-view 

[device] interface GigabitEthernet1/0/1 

[device-GigabitEthernet1/0/1] priority-trust cos 

z 

Configure to trust DSCP precedence on GigabitEthernet 1/0/1. 

Configuration procedure: 

<device> system-view 

[device] interface GigabitEthernet1/0/1 

[device-GigabitEthernet1/0/1] priority-trust dscp 

You can modify the COS-precedence-to-other-precedence, DSCP-precedence-to-other-precedence, 

and DSCP-precedence-to-DSCP-precedence mapping tables as required to mark packets with 

different priorities. 

The target COS-precedence-to-other-precedence, DSCP-precedence-to-other-precedence, and 

DSCP-precedence-to-DSCP-precedence mapping tables are determined. 

Follow these steps to configure the COS-precedence-to-other-precedence mapping table:
