Configuring Track

Overview

The Track module works between application modules and detection modules, as shown in
shields the differences between various detection modules from application modules.
Collaboration is enabled after you associate the Track module with a detection module and an
application module. 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. The
Track module sends the detection results to the associated application module. 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 associated tracked object to the Track module.
Depending on the result, the Track module changes the status of the track entry:
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.
