Tools > Network Discovery with an undiscovered subnet selected
If you have already performed a discovery operation, and a router was
detected during that discovery, then it is likely that you will have some
undiscovered subnets on your map. These subnets will be those to which
the router is directly attached and were not specified in the original
discovery.
Figure 28 Undiscovered Subnet
If you select one or more of these subnets in the map or the tree and
select Network Discovery from the Tools menu, the Network Discovery
wizard will be launched at the Specify Subnets pane. As with selecting an
existing subnet, the subnet information will be included in the list. The
range information will always default to All, although you can change
this if you wish by selecting the desired subnet in the list and clicking the
Edit button.
As with selecting discovered subnets, if you select an undiscovered
subnet in the tree or the map the right-click menu contains the Network
Discovery option. Selecting this has the same effect as selecting Network
Discovery from the tools menu.
You can also launch the Network Discovery wizard for an undiscovered
subnet by double-clicking on its icon in the map or tree. This has the
same effect as selecting Network Discovery from the tools menu.
The Network
Discovery Wizard
This step-by-step guide takes you through the Network Discovery wizard
in order to customize the discovery process. When you complete the
wizard the discovery process will be started.
If you have previously created a network map, you can use this wizard to
rediscover all of your network, part of it, or discover a completely new
part. The discovery process verifies the devices and links on the network
map and incorporates any changes. To do this, you must open the map
before starting the wizard.
