queue.

The following table describes the labels in this screen.

Table 32 Queue Setup: Add

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 3) 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 ZyXEL 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 ZyXEL 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.

Apply Click Apply to save your changes.

Cancel Click Cancel to exit this screen without saving.
