Queue Mode - Planet SGSD-1022 User Manual

5.23 Class of Service 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.
