queues are delayed until no more high priority data needs to be
sent. The Strict method always gives precedence to high priority
over low priority.
The 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.
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 frames will egress the switch as
soon as possible.
