DESCRIPTION
Select Enable or Disable to activate or deactivate the queue.
Enter the descriptive name of this queue.
Select the interface to which this queue is applied.
This field is read-only if you are editing the queue.
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.
Select the weight (from 1 to 8) of this queue.
If two queues have the same priority level, the VMG divides the bandwidth across the queues
according to their weights. Queues with larger weights get more bandwidth than queues with
smaller weights.
This field displays Drop Tail (DT). Drop Tail (DT) is a simple queue management algorithm that
allows the VMG 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).
Specify the maximum transmission rate (in Kbps) allowed for traffic on this queue.
Click OK to save your changes.
Click Cancel to exit this screen without saving.
