Configuration procedure
1. Configure trusting port priority
# Set the port priority of GigabitEthernet 1/0/1 to 3.
system-view
[Device] interface gigabitethernet 1/0/1
[Device-GigabitEthernet1/0/1] qos priority 3
[Device-GigabitEthernet1/0/1] quit
# Set the port priority of GigabitEthernet 1/0/2 to 4.
[Device] interface gigabitethernet 1/0/2
[Device-GigabitEthernet1/0/2] qos priority 4
[Device-GigabitEthernet1/0/2] quit
# Set the port priority of GigabitEthernet 1/0/3 to 5.
[Device] interface gigabitethernet 1/0/3
[Device-GigabitEthernet1/0/3] qos priority 5
[Device-GigabitEthernet1/0/3] quit
2. Configure the priority mapping table
# Configure the 802.1p-to-local mapping table to map 802.1p priority values 3, 4, and 5 to local
precedence values 2, 6, and 4. This guarantees the R&D department, management department, and
marketing department decreased priorities to access the public server.
