This section contains tutorials on how you can configure the QoS screen.

Let’s say you are a team leader of a small sales branch office. You want to prioritize e-mail traffic 
because your task includes sending urgent updates to clients at least twice every hour. You also 
upload data files (such as logs and e-mail archives) to the FTP server throughout the day. Your 
colleagues use the Internet for research, as well as chat applications for communicating with other 
branch offices.

In the following figure, your Internet connection has an upstream transmission bandwidth of 
10,000 kbps. For this example, you want to configure QoS so that e-mail traffic gets the highest 
priority with at least 5,000 kbps. You can do the following: 

• Configure a queue to assign the highest priority queue (1) to e-mail traffic going to the WAN 

interface, so that e-mail traffic would not get delayed when there is network congestion. 

• Note the IP address (192.168.1.23 for example) and/or MAC address (AA:FF:AA:FF:AA:FF for 

example) of your computer and map it to queue 7. 

Note: QoS is applied to traffic flowing out of the VMG.

Traffic that does not match this class is assigned a priority queue based on the internal QoS 
mapping table on the VMG.

QoS Example

Click Network Setting > QoS > General and select Enable. Set your WAN Managed Upstream 
Bandwidth to 10,000 kbps (or leave this blank to have the VMG automatically determine this 
figure). Click Apply.

10,000 kbps

IP=192.168.1.23

 

Other traffic: Automatic classifier

and/or
MAC=AA:FF:AA:FF:AA:FF
Email traffic: Highest priority
