10.5 The Classification 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 VMG 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.

Status This field displays whether the classifier is active or not. A yellow bulb signifies that this
classifier is active. A gray bulb signifies that this classifier is not active.
Class Name This is the name of the classifier.
Classification
Criteria
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.
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.
VLAN ID Tag This is the VLAN ID number assigned to traffic of this classifier.
To Queue This is the name of the queue in which traffic of this classifier is put.
Modify Click the Edit icon to edit the classifier.
Click the Delete icon to delete an existing classifier. Note that subsequent rules move
up by one when you take this action.
