10.4.1 Adding a QoS Queue

Click Add new Queue or the edit icon in the Queue Setup screen to configure a queue.

Figure 69 Queue Setup: Add

The following table describes the labels in this screen.

10.5 The Class Setup Screen

Use this screen to add, edit or delete QoS classifiers. A classifier groups traffic into data flows

according to specific criteria such as the source address, destination address, source port number,

destination port number or incoming interface. For example, you can configure a classifier to select

traffic from the same protocol port (such as Telnet) to form a flow.

LABEL DESCRIPTION

Active Select to enable or disable this queue.

Name Enter the descriptive name of this queue.

Interface Select the interface to which this queue is applied.

This field is read-only if you are editing the queue.

Priority Select the priority level (from 1 to 7) of this queue.

The smaller the number, the higher the priority level. Traffic assigned to higher priority

queues gets through faster while traffic in lower priority queues is dropped if the network is

congested.

Weight Select the weight (from 1 to 8) of this queue.

If two queues have the same priority level, the Device divides the bandwidth across the

queues according to their weights. Queues with larger weights get more bandwidth than

queues with smaller weights.

Buffer

Management

This field displays Drop Tail (DT). Drop Tail (DT) is a simple queue management

algorithm that allows the Device buffer to accept as many packets as it can until it is full.

Once the buffer is full, new packets that arrive are dropped until there is space in the buffer

again (packets are transmitted out of it).

Rate Limit Specify the maximum transmission rate (in Kbps) allowed for traffic on this queue.

OK Click OK to save your changes.
