to the output queues.
Example
queue mode
This command sets the queue mode to strict priority, Weighted
Round-Robin (WRR), or a combination of both for the class of service
(CoS) priority queues. Use the no form to restore the default value.
Syntax
queue mode {strict | wrr | hybrid}
no queue mode
•strict - Services the egress queues in sequential order, transmitting
all traffic in the higher priority queues before servicing lower priority
queues.
•wrr - Weighted Round-Robin shares bandwidth at the egress ports
by using scheduling weights 1, 2, 4, 6, 8, 10, 12, 14 for queues 0 - 7
respectively.
•hybrid - Strict priority is used for the high-priority queues and
Weighted Round-Robin for the rest of the queues. The high p riority
queues are specified by setting a queue’s bandwidth to zero with the
queue bandwidth command (page 33-7).

Command Usage
• The switch can be set to service the port queues based on stri ct
priority, WRR, or a combination of strict and weighted queueing.
• Strict priority requires all traffic in a higher priority queue to be
processed before lower priority queues are serviced.
