8.3 Configuring Class of Service
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.
8.3.1 Setting the Default Priority for Interface
Use the Traffic > Priority > Default Priority page to specify the default port priority for each
interface on the switch. All untagged packets entering the switch are tagged with the specified
default port priority, and then sorted into the appropriate priority queue at the output port.
