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. The default priority can be set for each
interface, also the queue service mode and the mapping of frame priority
tags to the switch's priority queues can be configured.
