indexes. (Range: 0–8 .There must be either 0 wrr queues or more than one.
If number-of-queues = 0, all queues are assured forwarding (according to
wrr weights) If the number-of-queues = 8 , all the queues are expedited
(strict priority queues).
Default Configuration
All queues are expedite queues.
Command Mode
Global Configuration mode
User Guidelines
An expedite queue is a strict priority queue, which is serviced until empty before
the other lower priority queues are serviced.
the weighted round robin (WRR) weight ratios are affected by the number of
expedited queues, because there are fewer queues participating in WRR. This
indicates that the corresponding weight in the wrr-queue bandwidth Interface
Configuration mode command is ignored (not used in the ratio calculation).
Example
The following example configures the number of expedite queues as 2.
switchxxxxxx(config)#
