Configuring Service Statistics Using the CLI Command
For information about the CLI command that performs this function, see the following chapter in the
CLI Reference Guide:

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.
