in the menu (left side of screen) to view, add and delete service flow
classifiers. Any active service flow must have at least one active classifier. The 802.16
Service Flow can have multiple classifiers (classification rules). New classifiers become
active after clicking Add on this screen.

When multiple classifiers are defined for one service flow, the index number is listed in
the form X.Y where:
the form X.Y where:
X == Service Flow index (SfId)
Y == Classifier index number
When a service flow is activated, the classifiers become active by default. A service flow
can have both active and inactive classifiers only when the service flow is already active
and new classifiers are added. New classifiers become active only after they are
successfully implemented on both the base station and the subscriber.

Important Information About Using Generic Classifiers
What is a Generic Classifier
A generic classifier is defined as any classifier with only the priority field enabled.
Behavior of Generic Classifiers
It is important to note that generic classifier filters behave differently based on the mode
of the learning function. See the following table.

A service flow and a generic classifier must be created for each subscriber using
the learning function. The generic classifier functions as a template. When a new
host is detected, the learning function automatically adds a new host-specific
classifier (based on the generic classifier definition) to the associated downlink
service flow. These host-specific classifiers are deleted automatically when the
subscriber de-registers.

No
The generic classifiers must be deleted when before Learning is disabled.
When Learning is disabled, the generic classifier functions as a pass-all filter and

forwarded only to a single subscriber or subset of subscribers.
Using the Learning Feature
To use the Learning feature (
Learning Enabled = Yes
) for any subscriber, it is necessary to
create a downlink service flow and assign a generic classifier. When a new host is
detected by the subscriber, this is reported to the base station and the learning function
automatically adds a new classifier to permit downlink traffic to that host. The generic
classifier filters traffic based on the service flow type:
