SELECTING THE
QUEUE MODE
Use the Traffic > Priority > Queue page to set the queue mode for the
egress queues on any interface. The switch can be set to service the
queues based on a strict rule that requires all traffic in a higher priority
queue to be processed before the lower priority queues are serviced, or
Weighted Round-Robin (WRR) queuing which specifies a scheduling weight
for each queue. It can also be configured to use a combination of strict and
weighted queuing.
