Attributes
To understand how Traffix Manager groups devices in the Map, it helps to
be familiar with the concepts of
attributes and groupings .
An attribute is a label for a piece of information about a device: for
example, location or IP address . Traffix Manager has a number of
predefined attributes; you can change these or add your own.
At any one time, each attribute of a particular device is either currently
unassigned (not defined), or has a single value. For example, the value of
the location of a device might be
Boston, or the location might be
unknown, or unassigned .
Predefined Attributes There are a number of predefined attributes in Traffix Manager that you
can use to create your own groupings. For these predefined attributes,
values are usually assigned automatically as each device is discovered.
You cannot delete a predefined attribute, or change its name.
