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,
Shaped Deficit Weighted Round-Robin (SDWRR) queuing that specifies a
scheduling weight for each queue. SDWRR is labelled WRR in the menu. It
