An object must exist before it can be added to a tracked list.
The NOT operator is specified for one or more objects and negates the state of the object.
Note
After configuring the tracked object, you must associate the interface whose state should be tracked and you
may optionally specify the number of seconds to wait before the tracking object polls the interface for its
state.
