Chapter 10 Quality of Service (QoS)
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 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.

|
Classification | This shows criteria specified in this classifier, for example the interface |
Criteria | from which traffic of this class should come and the source MAC |
| address of traffic that matches this classifier. |
|
|
DSCP Mark | This is the DSCP number added to traffic of this classifier. |
|
|
802.1P Mark | This is the IEEE 802.1p priority level assigned to traffic of this |
| classifier. |
