5.4 The QoS Classification Screen

Use this screen to add, edit or delete QoS classifiers. A classifier groups traffic into data flows according
to specific criteria such as the source address, destination address, source port number, destination port
number or incoming interface. For example, you can configure a classifier to select traffic from the
same protocol port (such as Telnet) to form a flow.
You can give different priorities to traffic that the FMG forwards through the WAN interface. Give high
priority to voice and video to make them run more smoothly. Similarly, give low priority to many large file
downloads so that they do not reduce the quality of other applications.
