Administrator Guide

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 notied. 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 notied of the event.
If the timer expires and an object’s state has changed, a notication is sent to the client. If no delay is congured, a
notication is sent immediately after a change in the state of a tracked object is detected. The time delay in
communicating a state change is specied in seconds.
