Chapter 22 Queuing Method

The following table describes the labels in this screen.

Table 59 Advanced Application > Queuing Method

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
Q0-Q7	different traffic queues according to their weights.
Hybrid-	This field is applicable only when you select WFQ or WRR.
SPQ	Select a queue (Q0 to Q7) to have the Switch use SPQ to service the subsequent queue(s) after
Lowest-	and including the specified queue. For example, if you select Q5, the Switch services traffic on
Queue	Q5, Q6 and Q7 using SPQ.
	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.
