Parameter

priority-level:Specifies the priority level of the port, ranging from 0 to 7.

Description

Use the priority command to configure the priority of Ethernet port.

Use the undo priority command to restore the default port priority.

By default, the priority level of the port is 0. The Switch replaces the 802.1p priority carried by a packet with the port priority that is defined.

Every port on the Switch supports eight packet egress queues. The Switch puts the packets into different egress queues according to their priorities.

When transmitting a packet, the Switch replaces the packet’s 802.1p priority with the priority of the received port, according to which the packet will be put into the corresponding egress queue.

Example

Set the priority of Ethernet1/0/1 port to 7.
