Type 2
Queuing Mechanism
Setting Description Factory Default
Weight Fair The Moxa switch has 4 priority queues. In the weight fair
scheme, an 8, 4, 2, 1 weighting is applied to the four priorities.
This approach prevents the lower priority frames from being
starved of opportunity for transmission with only a slight delay
to the higher priority frames.
Weight Fair
Strict In the Strict-priority scheme, all top-priority frames egress a
port until that priority’s queue is empty, and then the next
lower priority queue’s frames egress. This approach can cause
the lower priorities to be starved of opportunity for transmitting
any frames but ensures that all high priority fra
the switch as soon as possible.
