1. Ensure that your appliances are licensed for discovery.
2. Add the needed seed routers to each Probe appliance, as described in defining seed routers for probe members, see Configuring Discovery Propertiessee Defining Seed Routers for Probe Members.
3. Add the necessary SNMPv1/v2 and SNMPv3 credentials at the Grid level and/or Member/Probe level. For information about configuring SNMP1/v2 credentials for polling, configuring SNMPv3 properties, and defining seed routers for probe members, see Configuring Discovery Properties.
4. If necessary, add CLI Credentials, including device admin username/password tuples and Enable passwords, at the Grid level and/or Member/Probe level, as described in configuring CLI discovery properties  and testing SNMP and CLI Credentials, see Configuring Discovery Properties.
5. If necessary, enable the use of DHCP routers and servers as seeds to increase device discovery, as described in configuring SNMP1/v2 credentials for polling, see Configuring Discovery PropertiesSNMP1/v2 Credentials for Polling.
6. If you have extensive end host Ethernet segments connected to Ethernet switches, enable switch port discovery, as described in defining seed routers for probe members, see Configuring Discovery Propertiessee Defining Seed Routers for Probe Members.

With these settings, the Probe appliances automatically begin discovering network infrastructure devices.
You can elect to immediately discover or schedule discovery of new objects that you create and enable under IPAM or DHCP. Objects that allow immediate discovery include the following:

...

1. From the Data Management tab, select the IPAM tab. The IPAM Home page appears.
2. Select the network or other object over which you want to perform discovery.
   Depending on the object type, navigate from the network level to the individual IP table in the List page to locate the object for immediate discovery.
3. Expand the Toolbar and click Discover Now.
   You can also click the Action icon Image Removed for icon for the network and choose Discover Now from the menu.

The Probe member associated with the network or other object initiates a discovery procedure.

Smart Folders and Discovered Devices

Image Modified
Grid Manager maintains a Smart Folder titled Discovered Switches/Routers, under which appears a list of all routers, switches and switch-routers that thus far have been discovered and catalogued through discovery. Clicking a device name opens the device's main page, with Interfaces, Networks, IP Addresses, Assets and Components panels. For more information, see Managing Discovered Data.
Open the Smart Folders category under the Finder menu and click on the Discovered Switches/Routers folder. Clicking on a device name opens the device page under Data Management –> Devices and shows the Interfaces page for the chosen device. For related information, go to My Smart Folders and Predefined Smart Folders.

You use a dedicated Device Selector window to choose a discovered device for creating a port reservation with various IPAM objects such as IPv4 reservations, fixed addresses, host records, and provisioning of IPv4 and IPv6 networks on device interfaces; testing SNMP or CLI credentials, and other purposes, as shown in the following figure.:
