4.5 Tuning discovery

For general discovery performance, fine-tune the discovery configuration to discover only critical and important devices.

Filter by IP address range, system object ID, or both.
Limit discovery of non-SNMP devices and any SNMP devices (devices that are not switches or routers).
To delete one or more nodes from the NNMi database on the command line, use the nnmnodedelete.ovpl command. This command deletes nodes, but not seed definitions, from the NNMi database. To delete one or more seed definitions from the NNMi database on the command line, use the nnmseeddelete.ovpl command.
There are special discovery circumstances that might be remedied by suppressing discovery protocol collections. For details, see 19.19 Suppressing the use of discovery protocols for specific nodes.
