Method Select SPQ (Strictly Priority Queuing), WFQ (Weighted Fair Queuing) or
WRR (Weighted Round Robin).
Strictly Priority services queues based on priority only. When the highest
priority queue empties, traffic on the next highest-priority queue begins. Q7
has the highest priority and Q0 the lowest.
Weighted Fair Queuing is used to guarantee each queue's minimum bandwidth
based on their bandwidth weight (the number you configure in the Weight
field). Queues with larger weights get more guaranteed bandwidth than
queues with smaller weights.
Weighted Round Robin Scheduling services queues on a rotating basis based
on their queue weight (the number you configure in the queue Weight field).
Queues with larger weights get more service than queues with smaller
weights.
Weight When you select WFQ or WRR enter the queue weight here. Bandwidth is
divided across the different traffic queues according to their weights.

Queue This field is applicable only when you select WFQ or WRR.
Select a queue (Q0 to Q7) to have the Switch use Strictly Priority to service
the subsequent queue(s) after and including the specified queue. For example,
if you select Q5, the Switch services traffic on Q5, Q6 and Q7 using Strictly
Priority.
Select None to always use WFQ or WRR.
Apply Click Apply to save your changes to the Switch’s run-time memory. The
Switch loses these changes if it is turned off or loses power, so use the Save
link on the top navigation panel to save your changes to the non-volatile
memory when you are done configuring.
Cancel Click Cancel to begin configuring this screen afresh.
