Wrr-Queue Bandwidth - Dell PowerConnect 5324 Command Line Interface Reference Manual

User Guidelines
• You can use this command to distribute traffic into different queues, where each queue is
configured with different weighted round robin (WRR) parameters.
• To enable the expedite queues, use the priority-queue out Interface Configuration mode
command wrr-queue cos-map.
Example
The following example maps CoS 3 to queue 4.
Console (config)# wrr-queue cos-map 4 3

wrr-queue bandwidth

The wrr-queue bandwidth Interface Configuration mode command assigns Weighted Round
Robin (WRR) weights to egress queues. The weights ratio determines the frequency in which the
packet scheduler dequeues packets from each queue. To return to the default values, use the no
form of this command.
Syntax
wrr-queue bandwidth weight1 weight2 ... weight_4
no wrr-queue bandwidth
• weight1...weight_4—Sets the bandwidth ratio by the WRR packet scheduler for the
packet queues. Separate each value by spaces. (Range: 6 - 255)
Default Configuration
The default WRR weight is 1/4 ratio for all queues (each weight set to 6).
Command Mode
Interface Configuration (Ethernet, port channel) mode
User Guidelines
• The ratio for each queue is defined by the queue weight divided by the sum of all queue
weights (i.e., the normalized weight). This actually sets the bandwidth allocation of each
queue.
• A weight of 0 means no bandwidth is allocated for the same queue, and the share bandwidth
is divided among the remaining queues.
• All 4 queues are participating excluding the queues that are assigned as expedite queues. The
weights of these queues are ignored in the ratio calculation.
• All 4 queues participate in the WRR exclude the expedite queues, in which case the
corresponded weight is ignored (not used in the ratio calculation). The expedite queue is a
priority queue, and it is serviced until empty before the other queues are serviced.
