The Track module works between the application modules and the detection modules and is mainly
used to obscure the difference of various detection modules to provide a unified interface for application
modules.
Collaboration Between the Track Module and the Detection Modules
You can establish the collaboration between the Track module and the detection modules through
configuration. A detection module probes the link status and informs the Track module of the probe
result. The Track module then changes the status of the Track object accordingly:
z
If the probe succeeds, the status of the corresponding Track object is Positive;
z
If the probe fails, the status of the corresponding Track object is Negative.
At present, the detection modules that can collaborate with the Track module include the Network
Quality Analyzer (NQA) only. Refer to NQA in H3C WX6103 Access Controller Switch Interface Board
Configuration Guide for details of NQA.
Collaboration Between the Track Module and the Application Modules
You can establish the collaboration between the Track module and the application modules through
configuration. If the status of the Track object changes, the Track module tells the application modules
to deal with the change accordingly.
At present, the application modules that can collaborate with the Track module include:
z
Static routing
Track Configuration Task List
To implement the collaboration function, you need to establish collaboration between the Track module
and the detection modules, and between the Track module and the application modules.
Complete these tasks to configure Track module:

Configuring Track-NQA Collaboration
Through the following configuration, you can establish the collaboration between the Track module and
the NQA, which probes the link status and informs the Track module of the probe result.
Follow these steps to configure Track-NQA collaboration:
