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 eight 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.
