Queuing Mechanism – Type 2
Setting
Description
Factory
Default
Weight Fair
The Weidmüller 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 frames will egress the
switch as soon as possible.
