DESCRIPTION

Method

Select SPQ (Strictly Priority Queuing), WFQ (Weighted Fair Queuing) or WRR

 

(Weighted Round Robin).

 

Strictly Priority Queuing 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 portion (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.

 

 

Hybrid-

This field is applicable only when you select WFQ or WRR.

SPQ

Select a queue (Q0 to Q7) to have the Switch use SPQ to service the

Lowest-

subsequent queue(s) after and including the specified queue for the port. For

Queue

example, if you select Q5, the Switch services traffic on Q5, Q6 and Q7 using

 

 

SPQ.

 

Select None to always use WFQ or WRR for the port.

 

 

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.
