Configuring Track
Overview
The Track module works between application modules and detection modules, as shown in Figure
43. It shields the differences between various detection modules from application modules.
Collaboration is enabled when you associate the Track module with a detection module and an
application module, and it operates as follows:
1. The detection module probes specific objects such as interface status, link status, network
reachability, and network performance, and informs the Track module of detection results.
2. The Track module sends the detection results to the application module.
3. When notified of changes for the tracked object, the application modules can react to avoid
communication interruption and network performance degradation.

Collaboration fundamentals
The Track module collaborates with detection modules and application modules.
Collaboration between the Track module and a detection module
The detection module sends the detection result of the tracked object to the Track module. The Track
module changes the status of the track entry as follows:
If the tracked object operates correctly, the state of the track entry is Positive. For example, the
track entry state is Positive in one of the following conditions:
{ The target interface is up.
{ The target network is reachable.
If the tracked object does not operate correctly, the state of the track entry is Negative. For
example, the track entry state is Negative in one of the following conditions:
{ The target interface is down.
{ The target network is unreachable.
If the detection result is not valid, the state of the track entry is NotReady. For example, the track
entry state is NotReady if its associated NQA operation does not exist.
The following detection modules can be associated with the Track module:
