Intel® Blade Server Ethernet Switch Modules SBCEGBESW1 and SBCEGBESW10 CLI Guide 185
Default Configuration
The default WRR weight ratio is one-eighth of the sum of all queue weights (each weight
is set to 6).
Command Mode
Interface Configuration (Ethernet, port-channel) mode
User Guidelines
Use the priority-queue out num-of-queues Global Configuration mode command to
configure a queue as WRR or Strict Priority. Use this command to define a WRR weight
per interface.
The weight ratio for each queue is defined by the queue weight divided by the sum of all
queue weights (i.e., the normalized weight). This sets the bandwidth allocation for each
queue.
A queue can be assigned a WRR weight of 0, in which case no bandwidth is allocated to
the queue and the shared bandwidth is divided among the remaining queues.
All eight queues participate in the WRR, excluding the queues that are assigned as
expedite queues. The weights of the expedite queues are ignored in the ratio calculation.
An expedite queue is a priority queue, and it is serviced before the other queues are
serviced. Use the
priority-queue out Interface Configuration (Ethernet, port-channel)
mode command to enable expedite queues.
Example
The following example assigns a weight of 6 to each of the 8 WRR queues.
priority-queue out num-of-queues
The priority-queue out num-of-queues Global Configuration mode command
configures the number of expedite queues. To return to the default configuration, use the
no
form of this command.
Syntax
