Configuring Track

Overview

The Track module works between application 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:

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 functions correctly, for example, the target interface is up or the target
network is reachable, the state of the track entry is Positive.
•
If the tracked object does not function correctly, for example, the target interface is down or the
target network is unreachable, the state of the track entry is Negative.
•
If the detection result is not valid, for example, the network quality analyzer (NQA) test group
that is associated with the track entry does not exist, the state of the track entry is Invalid.
The following detection modules can be associated with the Track module:
•
NQA.
•
BFD.
•
Interface management module.
