Usage Information
You can configure an UP and/or DOWN timer for each tracked object to set the time
delay before a change in the state of a tracked object is communicated to clients. The
configured time delay starts when the state changes from UP to DOWN or vice-versa.
If the state of an object changes back to its former UP/DOWN state before the timer
expires, the timer is cancelled and the client is not notified. For example, if the DOWN
timer is running when an interface goes down and comes back up, the DOWN timer is
cancelled and the client is not notified of the event.
If the timer expires and an object’s state has changed, a notification is sent to the client.
If no delay is configured, a notification is sent immediately after a change in the state of
a tracked object is detected. The time delay in communicating a state change is
specified in seconds.
