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.
