4.8 Configuring QoS Queue and Class Setup
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

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
