Configuring Class of Service
The Class of Service (CoS) queueing feature lets you directly configure certain aspects of switch queueing.
This provides the desired QoS behavior for different types of network traffic when the complexities of
DiffServ are not required. The priority of a packet arriving at an interface can be used to steer the packet to
the appropriate outbound CoS queue through a mapping table. CoS queue characteristics that affect queue
mapping, such as minimum guaranteed bandwidth, transmission rate shaping, etc., are user-configurable at
the queue (or port) level.
Seven queues per port are supported. Although the hardware supports eight queues, one queue is always
reserved for internal use by the stacking subsystem.
