3.11 Configuring QoS Queue and Class Setup
This section contains tutorials on how you can configure the QoS screen.
Note: Voice traffic will not be affected by the user-defined QoS settings on the ZyXEL
Device. It always gets the highest priority.
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 (7) to e-mail traffic from
the LAN 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 ZyXEL Device.
Traffic that does not match this class is assigned a priority queue based on the
internal QoS mapping table on the ZyXEL Device.
