Object Tracking Configuration - Avaya G250 Administration

Configuring WAN interfaces
Using object tracking, different applications can register with the tracking process, track the
same remote device(s), and each take different action when the state of the remote device(s)
changes.

Object tracking configuration

The process of configuring object tracking on the G250/G350 consists of the following main
steps:
1. Configure RTRs to monitor remote devices and learn their state (up or down). Each RTR
has a state: inactive (not running), up (the remote device is considered up), or down (the
remote device is considered down).
2. Configure object trackers to track the states of RTRs. Each object tracker calculates its own
state (up or down) based on the states of the elements it is tracking.
Whenever the state of an object tracker changes, it notifies the applications registered with
it.
An object tracker calculates its own state as follows:
For an object tracker tracking a single RTR:
●
If the state of the RTR is up, the state of the object tracker is up.
●
If the state of the RTR is inactive or down, the state of the object tracker is down.
●
A track list applies a configurable formula (using a Boolean or a threshold calculation) to
●
the states of the objects comprising the list, and the result (up/down) is the state of the
track list. For example, if the configured formula is the Boolean AND argument, then the
state of the list is up if the state of all its objects is up, and down if the state of one or more
of its objects is down.
