Discovering the network using the command-line interface

As an experienced user, you can configure and track a network discovery using configuration files and database queries.

Discovery configuration files
Experienced users can configure the discovery by editing the discovery configuration files.
Retrieving extra information
You can configure the discovery agents to retrieve extra information from devices and store this information in the ExtraInfo column of the topology database.
Configuring trap forwarding
The SNMP trap multiplexer, the ncp_trapmux process, listens to a single port and forwards all the traps it receives to a set of host/socket pairs.
Filtering SNMP information from devices
You can filter out SNMP information when devices are queried by the SNMP helper by configuring inserts into the SNMP helper database.
