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.

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 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.
