All maps relate to a specific discovery scan file. For nodes on a specific map, based on all the discovered nodes in the scan file, NTM indicates that there are unseen neighbors that connect to a given node.


Clicking the Neighbors icon inset at the top right on a node, or right-clicking the node and selecting Add Neighbors, shows all nodes to which the selected node is connected. In many cases, the neighboring node is a network segment node. For detailed information about Network Segments, see Opening Maps from Earlier Versions of NTM.

In discovering your network based on your selections in the Discovery Wizard, and if there are more than 100 discovered nodes, NTM automatically shows all switches and routers on a default map (“Map1”). Use the Neighbors icon on these network devices to reveal more connections on the default map, as needed. Before revealing neighbors of device, if you want to know how many neighbors are currently hidden, hold the mouse over the device to see a summary that includes Hidden Neighbors.

As you increase the detail on the default map, consider selecting and copying sections of the map to a new map (File > New Map). This new map, along with any others you make based on the single scan file, will always appear in its own tab when you open the relevant scan file.

You can hide neighbors from a map either by undoing the action of revealing them (Edit > Undo) or simply by deleting them (right-click > Delete node). Nodes deleted from a map remain in the scan file and can be re-added to the same map or to any other map at any time.
