Class of Service Configuration
Class of Service (CoS) allows 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, and configure the mapping of frame priority tags to the switch’s
priority queues.
