190 Discovery
To enable full management functionality, including “deep discovery,” and advanced configuration
and provisioning capabilities, you must install the applicable Standard Devices Driver(s) to match
your network’s devices. (see Database Aging Policy Editor on page 718)
NOTE:
This software supports interface statistics collection only for devices which have a standard device
driver installed.
Example Workflow
The Resource Discovery screen sets up the process of retrieving network and device information for
the OpenManage Network Manager database.
1 Select Resource Discovery from the File -> Open -> Inventory menu, or from the Navigation
Window, or by clicking the magnifying glass icon in the toolbar to launch the Discovery
screen, open to the Discovery tab.
2 Click the New icon (far left) under Select Authentication.
3 The New / Edit Authentication screen appears. Select the Type of authentication, and fill in
the IP/Password fields as appropriate for the devices you want to discover. Click
Apply to
return to the original screen.
NOTE:
You can change the Timeout, Retries and Port for authentications on this screen. Make sure you adjust
the defaults to accommodate your network conditions.
4 Repeat the New authentication creation for as many authentications as are required. You will
typically need two authentications for each device, an SNMP authentication and a Telnet /
SSH authentication.
5 When you have configured the last of the authentications, enter the IP address(es) of the
device(s) you want to discover in the Discovery tab's IP Address field under Select Network
Type and Address. Notice that you can enter ranges as well as individual addresses, can
retrieve these addresses from a text file, and so on. The section below provides a complete
description of valid entries.
6 As you enter IP addresses, select the authentication that goes with each device by clicking the
second-from-the-left icon under Select Authentication.
7 Click Apply to accept the device / authentication combination.
8 The Select Network Address(es) and Authentication(s) screen appears. Notice that you can
click
Add to increase the list of addresses, Edit to revise what you have entered or Remove to
delete a listed item. Notice also that you can re-order the selection, and the order in which
devices are discovered, with the up/down top/bottom arrows below these buttons.
