Chapter 15 Quality of Service (QoS)

15.5 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 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.

DESCRIPTION
Click this button to create a new classifier.
This field displays the index number of the classifier.
Select the check box to enable the classifier.
This is the name of the classifier.
This shows criteria specified in this classifier, for example the interface
from which traffic of this class should come and the source MAC
address of traffic that matches this classifier.
This is the interface through which traffic that matches this classifier is
forwarded out.
This is the DSCP number added to traffic of this classifier.
This is the IEEE 802.1p priority level assigned to traffic of this
classifier.
