Figure 3-91. Queue Mode
CLI – The following sets the queue mode to strict priority service mode.
Setting 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 3-206, the
traffic classes are mapped to one of the eight egress queues provided for
each port. You can assign a weight to each of these queues (and thereby to
the corresponding traffic priorities). This weight sets the frequency at
which each queue will be polled for service, 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.
