The following table describes the labels in this screen.
Table 79 Advanced Application > Queuing Method
LABEL DESC RIPTIO N
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 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
We ig ht
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
We ig ht
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.
