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 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 , see Configuring about configuring SNMP1/v2 Credentials credentials for Pollingpolling, Configuring configuring SNMPv3 Properties, Defining Seed Routers for Probe Members, and Defining Seed Routers for Probe Membersproperties, 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 configuring CLI Discovery Properties discovery properties  and Testing 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 SNMP1/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 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:

• IPv4 Fixed Address (see see Configuring IPv4 Fixed Addresses for the complete procedure).
  You can Enable Immediate Discovery or Exclude from Network Discovery after creating the IPv4 fixed address, and override the SNMP credentials if necessary.
• IPv6 Fixed Address (see see Configuring IPv6 Fixed Addresses for  for the complete procedure).
  You can Enable Immediate Discovery or Exclude from Network Discovery after creating the fixed address, and override the SNMP credentials if necessary.
• IPv4 Reservation (see see Configuring IPv4 Reservations for  for the complete procedure).
  You can Enable Immediate Discovery or Exclude from Network Discovery after creating the IPv4 reservation, and override the SNMP credentials if necessary.
• Host (see see Adding Host Records for the complete procedure).
  You can Enable Immediate Discovery or Exclude from Network Discovery after creating the host, and override the SNMP credentials if necessary.
• IPv4 Network (see see Configuring IPv4 Networks for  for the complete procedure).
  You can Enable Immediate Discovery (option is enabled by default) and override inherited discovery Polling Options for the new network.
• IPv6 Network (see see Configuring IPv6 Networks for the complete procedure).
  You can Enable Immediate Discovery (option is enabled by default) and override inherited discovery Polling Options for the new network.
• IPv4 DHCP Range (see see Configuring IPv4 Address Ranges for  for the complete procedure).
  You can Enable Immediate Discovery (option is enabled by default) and override inherited discovery Polling Options for the new IPv4 DHCP range.
• IPv6 DHCP Range (see see Configuring IPv6 Address Ranges for  for the complete procedure).
  You can Enable Immediate Discovery (option is enabled by default) and override inherited discovery Polling Options for the new IPv6 address range.

You can manually perform discovery on any object at any time by selecting the object and choosing Image Removed Image Added Discover Now from the Toolbar. For more information, see see  the following section Object. When you do so, you see a status icon appear in the Discover Now data column
for the object under IPAM, in the Data Management –> DHCP page and other locations.
By default, Grid discovery settings are the prevailing settings for all newly created objects. You can override basic discovery polling options for networks and DHCP ranges allowing immediate discovery.
In such cases, local settings take priority. Credentials cannot be overridden for networks and DHCP ranges,

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.

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 to My Smart Folders and Predefined Smart Folders.

Using the Device Selector

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 Figure 15.3.

Using the Device Selector Window

 
The chosen device is discovered and listed in the Devices panel in IPAM, or any other device on the network under the All Devices category in the left pane of the device selector.
Clicking a managed device's device name selects the device and brings you back to the originating page. Otherwise, select a device and click OK to continue.
If you have a long list of devices even after selecting a smart folder, enter a device name search value or a search expression in the Find field and click Go.

Tips for Quick Navigation

To locate interface and device information quickly, along with associated IPAM objects that may be associated with elements such as port reservations, you can use Device and Interface terms in Global Search. (For additional information on Global Search, see Global Search About the Grid Manager Interface.)
Smart Folders provide another means of locating items such as IP addresses and IPAM objects of various types. Smart Folders provides additional filters for Device Type, Vendor, Model and Version. In a Smart Folder containing interfaces, you can filter by Admin Status, Operation Status, Trunk Status, VLAN ID or VLAN Name, and Description.
Using Smart Folders, you can also isolate all objects of a certain type by creating a smart folder with settings such as: Type equals IPv4 Fixed Address. Title the smart folder appropriately, to make clear what data set it is presenting.
