Command Attributes
• WRR - Weighted Round-Robin shares bandwidth at the egress ports by using
scheduling weights 1, 2, 4, 6 for queues 0 through 3 respectively. (This is the
default selection.)
• Strict - Services the egress queues in sequential order, transmitting all traffic in the
higher priority queues before servicing lower priority queues.
Web – Click Priority, Queue Mode. Select Strict or WRR, then click Apply.
Figure 3-74. Selecting the 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 3-122, the traffic classes are mapped to one of
the four 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.
Command Attributes
• WRR Setting Table* – Displays a list of weights for each traffic class (i.e., queue).
• Weight Value – Set a new weight for the selected traffic class. However, note that
Queue 0 is fixed at a weight of 1, and cannot be configured. (Range: 1-31)
* CLI shows Queue ID.
