10.5 The Class Setup 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 VDSL Router forwards out 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.
