an attribute New Device to the value TRUE. NL Type is a built-in
attribute which is always set to the network type of a device. This
means that every IP device is assigned the attribute New Device with a
value of TRUE.
■
Because of the while loop in the program, the program keeps
assigning attributes for devices until Traffix Manager is finished with it.
By replacing this simple loop with your own code, you can write a
program which assigns your own attributes to devices using your own
algorithm.
GetAttribute
returns the value of any attribute which has already
been assigned, for example, NL Address and NL Type. See “Predefined
Attributes” on page 40 for a list of attributes which are automatically
assigned by Traffix Manager. If you have other attribute lookup programs
running, you may also use
GetAttribute
to get an attribute value
assigned by another program.
Writing and Building
Your Own Attribute
Lookup Program
To build your own attribute lookup program, you should copy one of the
example programs and modify it. You can also look at these programs for
more examples of how to write attribute lookup programs. There are 6
example programs supplied, as shown in
.
