Displaying the Service Weight for Traffic Classes

This switch uses the Weighted Round Robin (WRR) algorithm to determine the
frequency at which it services each priority queue. As described in "Mapping CoS
Values to Egress Queues" on page 3-255,
the traffic classes are mapped to one of
the four egress queues provided for each port. This weight sets the limit for the
number of packets the switch will transmit each time the queue is serviced, and
subsequently affects the response time for software applications assigned a specific
priority value.

Note:

This switch does not allow the queue service weights to be set. The weights are
fixed as

1, 2, 4, 8, for queues 0 through 3 respectively.
