qos queue-type wrr <weight1> <weight2> <weight3> <weight4>

Command History
Release 5.1
Functional Notes
The actual weight is a calculated value based on the sum of all entered weights. It is the ratio of the
individual weight over the sum of all weights.
For example:
If the user enters 10, 20, 30, and 40 as the weight values, the first queue will have a ratio of 1/10. This is
derived from the formula 10/(10+20+30+40). Therefore, this queue will transmit 1 packet out of every 10
opportunities.
Usage Examples
The following example configures weights for all four queues:
(config)#qos queue-type wrr 10 20 30 40
60000CRG0-35E
Sets the weight of each queue (up to four). All queue weights must be
greater than zero, except for the weight for the last queue (queue 4). The
range for queues 1 to 3 is 1 to 255. The range for queue 4 is 0 to 255.
The queue 4 entry can be replaced by the expedite command. If set to
expedite, then it becomes a high-priority queue. All outbound traffic is
transmitted on an expedite queue prior to any other traffic in other queues.
