LABEL DESCRIPTION
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.
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.
Q0-Q7 This field is applicable only when you select WFQ or WRR.
Select a queue (Q0 to Q7) to have the Switch use Strictly Priority to service the
subsequent queue(s) after and including the specified queue for the 1000Base-T,
1000Base-X and 10 Gigabit 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.
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.
