uses discovery-time rule sets in order to understand device boundaries. Properties that identify a device as a distinct entity include MAC address, network address, SNMP System Name, and NetBIOS characteristics. As Discovery harvests device information, these device-distinguishing characteristics help to recognize and merge device records belonging to a single physical or virtual device.
註: For special environments, you can provide hints to to override normal device record merging using Address Exceptions.

- Device 2 IP. Network (IP) address of secondary device merged with primary.
