A full discovery with full topology split should be used only for an initial discovery or after a major network redesign. Thereafter, incremental discovery with incremental topology split should be used for normal topology updates.
An initial full discovery with full topology split can take a long time to complete. It consists of the time that the Topology Split Manager takes to discover the topology in the managed IP network plus the time that the topology-split algorithm takes to assign the discovered devices to the IP Availability Managers plus the time that the IP Availability Managers take to discovery the devices that have been assigned to them. While discoveries on the IP Availability Managers are in progress, the IP Availability Managers cannot monitor the network.
