The term router in this document refers to access controllers, access controller modules, and wireless
switches.
Track overview
Introduction to collaboration
The track module works between application and detection modules, as Figure 16 shows. It hides the
differences among detection modules from application modules.
Collaboration is enabled after you associate the track module with a detection module and an
application module respectively. The detection module monitors 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, and the
application module takes actions when the tracked object changes its state.

Collaboration fundamentals
The track module collaborates with detection modules and application modules:
• Collaboration between the track module and a detection module
• Collaboration between the track module and an application module
Collaboration between the track module and a detection module
After being associated with a track entry, the detection module sends the detection result of the tracked
object to the track module, which then changes the status of the track entry:
• If the tracked object functions properly, for example, the target interface is up or the target network
is reachable, the state of the track entry is Positive.
