P-870HW-51a v2 User’s Guide

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 ZyXEL Device 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.
