Now B should be able to receive traffic from A. You may need to additionally configure B’s firewall settings to allow specific traffic to pass through.

2.7 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 (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 P-870HN-51D.

Traffic that does not match this class is assigned a priority queue based on the internal QoS mapping table on the P-870HN-51D.
