ZyXEL Communications EX5501-B0 User Manual page 56

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 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.
QoS Example
Your computer
IP=192.168.1.23
and/or
MAC=AA:FF:AA:FF:AA:FF
E-mail traffic: Highest priority
Click Network Setting > QoS > General and click the QoS button to enable. When the switch goes to the

right ( ), the function is enabled. Set your WAN Managed Upstream Bandwidth to 10,000 kbps (or
leave this blank to have the Zyxel Device automatically determine this figure). Click Apply.
