Figure 134: Setting the Default Port Priority
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.
Command Usage
◆
Strict priority requires all traffic in a higher priority queue to be processed
before lower priority queues are serviced.
◆
WRR queuing specifies a relative weight for each queue. WRR uses a predefined
relative weight for each queue that determines the percentage of service time
