Network discovery
Network Discovery discovers the internal IP networks and subnets within your organization.
How network discovery works
Discovery uses the information it gathers to update routers and Layer 3 switches in the CMDB. A single MID Server that begins its scan on a configurable list of starting (or seed) routers performs network Discovery. Typically, the starting routers are the default routers used by all the MID Server host machines in the network, but can be any designated routers. The MID Server uses the router tables on the starting routers to discover other routers in the network. The MID Server then spreads out through the network, using router tables it finds to discover other routers. It continues until all the routers and switches have been explored.
After running Network Discovery, convert the IP networks it finds into IP address Range Sets that you use in Discovery schedules to discover configuration items (CI).
Configure SNMP credentials or (optionally) SSH credentials. Port 161 must be open for SNMP access and port 22 for SSH access.

Procedure
Convert IP networks into Discovery range sets
After you conduct a network Discovery, you must convert the IP networks that were found into range sets for use in discovering other devices.

What to do next
Add a Discovery range set to a Discovery schedule
After creating discovery range sets from a network discovery, add the sets to a discovery schedule. This process narrows down the range of IP addresses that Shazzam probes can scan. You can also add a behavior.
