You must have read/write permission to Network Discovery to initiate a discovery. After you start a discovery, you cannot change the configuration of the discovery, but you can start the discovery process immediately or schedule it for a later date. You can also configure a recurring discovery that repeats on a regular basis. For information, see Configuring and Starting an IP discovery and Scheduling IP Discovery below. The appliance saves the configuration of the last discovery.
When you start an IP discovery from the IPAM Home, Net Map or Network List panel, you can select the networks on which you want the discovery to run. When you start an IP discovery from the IP Map or IP List panel, the discovered network is the one to which the IP addresses belong. You can include additional networks when you configure the IP discovery from the Discovery Manager wizard. You can run an IP discovery on multiple networks in one network view.

From the Data Management tab, select the IPAM tab, and then select Discovery -> Discover Now from the Toolbar.
In the Discovery Manager wizard, click the IPv4 Device Discovery tab, and then complete the following in the Basic tab:
Mode: Select the IP discovery method you want to use. For information, see Supported IP Discovery Methods . If you select TCP or FULL, ensure that you configure the TCP ports in the Advanced tab. The default is FULL.
Click the Add icon to add networks. In the Network Selector dialog box, select the network view and networks. Use SHIFT+click and CTRL+click to select multiple networks. You can also use filters or the Go to function to find a specific network. For information, see Using Filters and Using the Go To Function.
. You can do the following in the table:Click the Add icon again to add more networks.
Select a network or multiple networks in the network table and click Delete to delete them.
Click the Export icon to export the data in CSV format.
Click the Print icon to print the data.
Disable: Select this to exclude an IP discovery task. IP discovery is enabled by default.
If you select TCP or FULL in Mode, click the Advanced tab and complete the following:
TCP Scan Technique: Select the TCP technique you want to use for the discovery. The default is SYN. For information, see TCP.
In the port table, select the checkbox of the port you want to configure. You can select all ports by clicking the checkbox in the header.
Optionally, you can click the Add icon and complete the following to add a new service to the list.Port: Enter the port number you want to add to the list. You must enter a number between 1 and 65535.
Service: Enter the name of the service.
You can also delete a specific TCP port in the list. You can select multiple ports for deletion.
Timeout (ms): Enter the timeout value in milliseconds for the discovery. The timeout value determines how long the discovery waits for a response from an IP address after probing it. The minimum is 5 and the maximum is 4000. The default is 1000.
Attempts: Enter the number of times you want the discovery to probe an IP address when scanning a network. The minimum is 1 and the maximum is 5. The default is 2.
Click Save to save the discovery configuration. Note that you must save the configuration before you can start a discovery.
Click Start to start the IP discovery. You can also do one of the following:
Restore to Defaults: Restore the discovery configuration using the default values.
Pause: Pause a running discovery.
Resume: Resume the discovery that has been stopped.
Save: Save the discovery configuration.
Close: Cancel the configuration. If you have started a discovery, the discovery runs in the background when you click Close. For information, see Running Tasks in the Background.
