After you associate a track entry with an apply clause, the detection module associated with the track
entry sends Track the detection result of the availability of the tracked object.
• The Positive state of the track entry indicates that the object is available, and the apply clause is
valid.
The Negative state of the track entry indicates that the object is not available, and the apply clause
•
is invalid.
The NotReady state of the track entry indicates that the apply clause is valid.
•
The following objects can be associated with a track entry:
• Output interface.
Next hop.
•
Default output interface.
•
