Table 4-2-6-1 SLA Parameters
4.2.6.2 Track
Track setting is designed for achieving linkage among SLA module, Track module and Application module.
Track setting is located between application module and SLA module with main function of shielding the
differences of various SLA modules and providing unified interfaces for application module.
Linkage between Track Module and SLA module
Once you complete the configuration, the linkage relationship between Track module and SLA module will
be established. SLA module is used for detection of link status, network performance and notification of
Track module. The detection results help track status change timely.
- For successful detection, the corresponding track item is Positive.
- For failed detection, the corresponding track item is Negative.
Linkage between Track Module and Application Module
After configuration, the linkage relationship between Track module and A pplication module will be
established. When any change occurs in track item, a notification that requires corresponding treatment
will be sent to
A pplication module.
Currently, the application modules like VRRP, WAN failover and static routing can get linkage with track
module.
If it sends an instant notification to A pplication module, the communication may be interrupted in some
circumstances due to routing's failure like timely restoration or other reasons. Therefore, user can set up a
period of time to delay notifying application module when the track item status changes.
