NerveCenter Discovery

Though you can manually add nodes to NerveCenter, it is easy to configure NerveCenter to discover nodes. When NerveCenter discovery is enabled, if the database does not already contain a node that sends it an SNMP trap or NerveCenter inform, NerveCenter adds that node to the database.

NerveCenter Configured To Discover Nodes

After installing NerveCenter, you can use the NerveCenter Administrator to define subnet IP filters that limit the sets of nodes NerveCenter can monitor. These filter values are stored with the NerveCenter configuration settings.

When a trap is received from a node, NerveCenter compares the node against those that are already in its database and confirms whether the node falls within the subnet IP filters you defined. Nodes that fall within the subnet range but are not in the database are added to the database.

Note    NerveCenter can be configured to process SNMP traps from nodes that reside outside the defined subnet filters. These nodes, however, are not added to the database. For information about these traps or about configuring subnet filters in Administrator, refer to the Managing NerveCenter online guide that is shipped with NerveCenter.

You can also use NerveCenter's ping sweep utility, IPSweep, to populate your database. See IPSweep for more information about IPSweep.
