4.11 Configuring QoS to Prioritize Traffic

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 you want to configure QoS so that e-mail traffic gets the highest priority. You
can do the following:
• Configure a queue to assign the highest priority queue (1) to e-mail traffic from the LAN
interface, so that e-mail traffic would not get delayed when there is network congestion.
• Note the MAC address (AA:FF:AA:FF:AA:FF for example) of your computer and map it to queue
1.
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.
