Queuing Method

 

 

LABEL

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 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.

FE Port

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 the

Enable

subsequent queue(s) after and including the specified queue for the 10/100 Mbps Ethernet

 

ports. 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 for the 10/100 Mbps Ethernet ports.

 

 

Port

This label shows the port you are configuring.

 

 

*

Settings in this row apply to all ports.

 

Use this row only if you want to make some settings the same for all ports. Use this row

 

first to set the common settings and then make adjustments on a port-by-port basis.

 

Note: Changes in this row are copied to all the ports as soon as you make

 

them.

Weight

When you select WFQ or WRR enter the queue weight here. Bandwidth is divided across

 

the different traffic queues according to their weights.

GE Port

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 the

Enable

subsequent queue(s) after and including the specified queue for the gigabit ports. 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 for the gigabit ports.

 

 

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
