When a device has more than one physical interface to one or more networks, it is known as a multi-homed device. You can discover and manage multi-homed devices.
When a multi-homed device is discovered, only one instance of the object is created in the MDB. However, objects that represent each of the device’s IP addresses appear on the 2D Map and in the Topology Browser.
Note: The only multi-homed devices that Continuous Discovery supports are routers.
Note: By default, interface objects are not created for non-router and single NIC devices. To enable this, set the InterfaceForAllDevices registry key under HKEY_LOCAL_MACHINE\SOFTWARE\ComputerAssociates\Discovery to true. This key is set to false by default.
After Discovery discovers devices on your network, the classification engine then classifies these devices according to how you have configured the classification engine. Continuous and Classic Discovery use the same classification engine. The classification engine configuration files let you customize the discovery rules to your environment.
Classification means that a class and subclass is defined for each discovered object, it is added to the MDB, and you can manage the object using CA NSM.
