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 will be 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 can be configured.
