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.
