During the initial full discovery, the IP Manager populates its repository with the topology that is discovered in the managed network environment. During any subsequent full discovery, the IP Manager attempts to rediscover the topology in its repository.

Rediscovering the topology reveals any changes in the configuration or connectivity of the managed systems and keeps the topology current. For example, if a card is added to a switch, the IP Manager must rediscover the switch so that it can add the new card to the topology. And if new systems have been added to the network and autodiscovery is enabled, the IP Manager will discover the new systems during the rediscovery.
