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
