Chapter 9 Quality of Service (QoS)

VMG1312-T10C User’s Guide

Use this screen to configure a queue. Click the Edit icon next to a QoS queue. 

Queue Setup: Edit 

The following table describes the labels in this 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 Device 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. 

Queue Setup: Edit

Active

Select to enable or disable this queue.

Name

Enter the descriptive name of this queue.

Interface

Select the interface of this queue.

Priority

Select the priority level (from 1 to 7) of this queue.

The lower 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 15) of this queue. 

If two queues have the same priority level, the Device divides the bandwidth across the 
queues according to their weights. Queues with larger weights get more bandwidth 
than queues with smaller weights.

Rate Limit

Specify the maximum transmission rate (in Kbps or %) allowed for traffic on this queue.

OK
