DESCRIPTION
Select SPQ (Strict Priority Queuing, WFQ, or WRR (Weighted Round
Robin).
Strict Priority Queuing (SPQ) 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 Scheduling (WFQ) is used to guarantee each queue's
minimum bandwidth based on their bandwidth portion (weight), the
number you assign in the Weight field. Queues with larger weights get
more guaranteed bandwidth than queues with smaller weights.
Weighted Round Robin Scheduling (WRR) 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.
When you select WRR or WFQ, enter the queue weight here. Bandwidth
is divided across the different traffic queues according to their weights.
Queues with larger weights get more service than queues with smaller
weights.
When you select WRR or WFQ, select a queue (Q0~Q7) to have the
switch use SPQ to service the specified queue and subsequent queues.
For example, if you select Q5, the switch services traffic on Q5, Q6, and
Q7 using SPQ. Select None if you want to always use WRR or
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.
Click Cancel to begin configuring this screen afresh.
