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 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.
