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.
You can give different priorities to traffic that the VMG forwards out through the WAN interface.
Give high priority to voice and video to make them run more smoothly. Similarly, give low priority
to many large file downloads so that they do not reduce the quality of other applications.
Click
Network Setting >
QoS > Class Setup
to open the following screen.
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 VMG 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 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).
Rate Limit
Specify the maximum transmission rate (in Kbps) allowed for traffic on this queue.
