Configuring WAN Queue Settings

Use the Queue Settings page to determine how traffic in queues is handled for each WAN port. The security appliance supports six queues for the WAN ports,

Q1 to Q6. There are three ways of determining how traffic in queues is handled:

Strict Priority (SP)	Egress traffic from the highest-priority queue (Q1) is
	transmitted first. Traffic from the lower queues is
	processed only after the highest queue has been
	transmitted, thus providing the highest level of priority
	of traffic to the highest numbered queue.
Weighted Round	Distributes the bandwidth between the classes using
Robin (WRR)	the weighted round robin scheme. The weights decide
	how fast each queue can send packets. In WRR mode
	the number of packets sent from the queue is
	proportional to the weight of the queue. The higher the
	weight, the more frames are sent.
Low Latency	The default setting, Low Latency Queuing (LLQ) allows
Queuing (LLQ)	delay-sensitive data (such as voice) to be given
	preferential treatment over other traffic by sending it
	first. You can enter the PQ for Q1 and a description for
	each queue. By default the PQ is 1200 Kbps. The
	Queue Descriptions are:
	Q1—Voice traffic
	Q2—Signaling
	Q3—Routing/VPN control
	Q4—Management
	Q5—Video
	Q6—Best Effort
