Quidway S2000 Series Ethernet Switches Chapter 2 QoS Commands
2-2
Description
Using priority command, you can configure the priority of Ethernet port. Using undo
priority command, you can restore the default port priority.
By default, the port priority is 0.
Every port of Ethernet switch supports two packet egress queues. The switch puts the
packets into different egress queues according to their priorities. The system puts the
packets with 802.1p priorities ranging from 0 to 3 into the lower-priority queue and
those with 802.1p priorities ranging from 4 to 7 into the higher-priority queue.
You can set a priority for a port and replace the 802.1p priority carried in the packet
with it. After transmitting a packet, the switch will replace the packet 802.1p priority
with the priority of the received port, according to which the packet will be put into the
corresponding egress queue so as to realize QoS function.
