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 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.
