DESCRIPTION
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.
This field is applicable only when you select WFQ or WRR.
Select a queue (Q0 to Q7) to have the Switch use SPQ to service the
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 SPQ.
Select None to always use WFQ or WRR for the 10/100 Mbps Ethernet ports.
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.
When you select WFQ or WRR enter the queue weight here. Bandwidth is
divided across the different traffic queues according to their weights.
This field is applicable only when you select WFQ or WRR.
Select a queue (Q0 to Q7) to have the Switch use SPQ to service the
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 SPQ.
Select None to always use WFQ or WRR for the gigabit ports.
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.
