To start discovery on connected networks, complete the following:
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:
During configuration, you can choose to Exclude from Network Discovery if you wish to postpone discovery for specific object types.
Individual IP addresses within a network, and specific object types (IPv4 reservation, fixed address, and host), may be excluded from discovery. You must explicitly select Enable Discovery for other object types (IPv4 and IPv6 Ranges, IPv4 and IPv6 Networks); you can optionally Enable Immediate Discovery.
If you choose not to perform immediate discovery, but do Enable Discovery, the new network or other object is discovered at a normal time determined by Network Insight.
You can manually perform discovery on any object at any time by selecting the object and choosing 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,
If after you select a a network, object or IP and the Discover Now button is not enabled, make sure the network or other object has a discovery Probe member assigned to it.
After you create any supported IPAM object, you may wish to perform discovery on it at a later time. You can simply select the object and discover it.
The Probe member associated with the network or other object initiates a discovery procedure.
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 Figure 15.3.
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.
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.)
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.
