1.3 Setting Port Priority

If a received packet is not VLAN-tagged, the switch will tag the packet with the default
VLAN tag of the port receiving the packet. In this case, the port priority of the port
receiving the packet is assigned to the 802.1p priority of the VLAN tag of the packet. In
this case, you can set the port priority.
If the received packet is VLAN-tagged, the switch does not perform the operation
above.
I. Configuration prerequisites
The port whose priority is to be configured is specified
The priority value of the specified port is specified
II. Configuration procedure
Follow these steps to set port priority:
To do...
Enter system view
Enter Ethernet port
view
Set the port priority
III. Configuration example
# Set the port priority of Ethernet 2/0/1 to 7.
<H3C> system-view
[H3C] interface Ethernet2/0/1
[H3C-Ethernet2/0/1] undo priority
[H3C-Ethernet2/0/1] priority 7
1.4 Configuring Priority According to Which a Packet is Put
into an Output Queue
When congestion occurs in the network, queue scheduling is generally adopted to
solve the problem that multiple packets compete for resources.
