DESCRIPTION
This label shows the port you are configuring.
Select SPQ (Strictly Priority Queuing), WFQ (Weighted Fair Queuing) or
WRR (Weighted Round Robin).
SPQ 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.
WFQ 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.
WRR 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.
When you select WFQ or WRR, enter the queue weight here. Bandwidth
is divided across the different traffic queues according to their weights.
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
example, if you select Q5, the Switch services traffic on Q5, Q6 and Q7
using SPQ.
Select None to always use WFQ or WRR.
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.
