4.3.15 Priority Commands
The commands described in this section allow you to specify which data packets
have greater precedence when traffic is buffered in the switch due to congestion.
This switch supports COS with four priority queues for each port. Data packets in a
port’s high-priority queue are transmitted before those in the lower-priority queues.
You can set the default priority for each interface, the relative weight of each queue,
and the mapping of frame priority tags to the switch’s priority queues.
