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 application module will be
established. When any change occurs in track item, a notification that requires corresponding treatment
will be sent to Application 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 Application 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.

Description
Track index. Up to 10 track settings can be configured. Range:
1-10.
The options are "sla" and "interface".
Defined SLA ID.
Select the interface whose status will be detected.
When interface is down or SLA probing fails, it will wait
according to the time set here before actually changing its
status to Down. Range: 0-180 (0 refers to immediate
switching).
When failure recovery occurs, it will wait according to the time
set here before actually changing its status to Up. Range:
0-180 (0 refers to immediate switching).
