Discovery Configuration
A discovery range is a network segment registered in OpenManage Essentials for the purpose of discovering devices.
OpenManage Essentials attempts to discover devices on all registered discovery ranges that are enabled. A discovery range includes subnet, a range of IP addresses on a subnet, an individual IP address, or an individual host name. Specify the IP address, IP address range, or host name for the discovery process. For more information, see
Discovery Configuration Options
Field
Group Name
IP address / range
Description
Specifies the group name for a set of devices.
Specifies the IP address or IP address range.
The following are examples of valid discovery range type address specifications (* is the wildcard character, meaning all possible addresses in the specified range):
• 193.109.112.*
• 193.104.20-40.*
58
Field
Discovery Range Name
Host name
Subnet mask
Import
Description
• 192.168.*.*
• 192.168.2-51.3-91
• 193.109.112.45-99
• System IP address—193.109.112.99
NOTE: Click Add to add multiple ranges of IP addresses. IPV6 addresses are not supported.
Specifies the discovery range name for the IP address/ range.
Specifies the host name, for example, mynode.mycompany.com.
Click Add to add multiple host names.
NOTE: You can add multiple host names by separating them using commas.
NOTE: Invalid characters in the host name are not checked. If the host name you provide contains invalid characters, the name is accepted. However, the device is not found during the discovery cycle.
Specifies the subnet mask for the IP address range. The subnet mask is used to determine the broadcast addresses for the subnet(s) part of the range. The
OpenManage Essentials Network Monitoring Service does not use the broadcast address when discovering devices in an IP address range. The following are examples of valid subnet mask specifications:
• 255.255.255.0 (The default subnet mask for a Class
C network.)
• 255.255.0.0 (The default subnet mask for a Class B network.)
• 255.255.242.0 (A custom subnet mask specification.)
By default, the subnet mask is set to 255.255.255.0.
Select this option to import host names and IP addresses from a file that is in CSV format. However, you can import only 500 line items per task. You can import different discovery ranges with different subnet masks. For example, 192.168.10.10, 255.255.255.128, 10.10.1.1,
255.255.0.0, and 172.16.21.1, 255.255.128.0.
You can use an Active Directory export file in a.CSV format as input. You can also create a .CSV file in a spreadsheet editor using the header
Name
and filling in system IP addresses or host names in the rows below the header (one per cell). Save the file in a .CSV format and use it as the input with the import feature. If there are any invalid entries in the file, a message is displayed when the data is imported by OpenManage Essentials. For an example of a CSV file, see
Specifying IPs, Ranges, or Host
.

SNMP Configuration
SNMP provides an interface to manage devices on the network such as servers, storage, switches, and so on. The
SNMP agent on the device allows OpenManage Essentials to query the health and inventory data of the device. See
to discover and inventory servers, storage devices, and other network devices.
For more information, click

Community is a read-only password that SNMP agents installed on managed devices use for authentication. The
Get Community allows OpenManage Essentials to browse and retrieve SNMP data. This field is case-sensitive.
OpenManage Essentials uses the first successful community name to communicate with the device. You can enter multiple SNMP community strings separated with commas.
Specifies or edits the community name for SNMP set calls from the OpenManage Essentials UI. The Set community is a read-write password that SNMP agents installed on managed devices use for authentication. The Set community allows OpenManage Essentials to perform tasks that require the SNMP protocol, such as shutting down a system. This field is case-sensitive. OpenManage
Essentials uses the first successful community name to

Essentials waits after issuing a get or set call before it considers the call failed. A valid range is from 1 to 15 seconds. The default is 4 seconds.
Specifies or edits the number of times that OpenManage
Essentials reissues a get or set call after the first call times out. A valid range is from 1 to 10 retries. The default is 2.
WMI Configuration
