DESCRIPTION

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.

 

 

Hybrid-

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

SPQ

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

Lowest

the subsequent queue(s) after and including the specified queue. For example,

Queue

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.
