If the state of an object changes back to its former UP/DOWN state before the timer expires, the timer iscancelled and the client is not notified. For example, if the DOWN timer is running when an interface goes downand 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, anotification is sent immediately after a change in the state of a tracked object is detected. The time delay incommunicating a state change is specified in seconds.Related Commands • track interface ip routing – configure object tracking on the routing status of an IPv4 Layer 3 interface.• track interface line-protocol – configure object tracking on the line-protocol state of a Layer 2 interface.• track ip route metric threshold – configure object tracking on the threshold of an IPv4 route metric.• track ip route reachability – configure object tracking on the reachability of an IPv4 route.descriptionEnter a description of a tracked object.Syntax description {text}To remove the description, use the no description {text} command.Parameters text Enter a description to identify a tracked object (80 characters maximum).Defaults NoneCommand Modes OBJECT TRACKING (conf_track_object-id)Command History This guide is platform-specific.
