 Chapter 9 Quality of Service (QoS)

EMG5324-D10A User’s Guide

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. 

Click Network Setting > QoS > Class Setup to open the following screen.

Network Setting > QoS > Class Setup 

Priority

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

The larger 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) allowed for traffic on this queue.
