2.6 How to Prioritize Traffic Using QoS Class and Queue

This tutorial shows you how to group traffic and give priorities using QoS. 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 from the LAN1
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 the queue.
Note: QoS is applied to traffic flowing out of the Device.
