Field Description

Subnet mask 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.

Import 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 Names.

Device Type Filtering

The Device Type Filtering options are displayed in the Discover Devices wizard, if Guided Wizard is

selected in Discovery Settings. This window enables you to select device types for discovery. After the

device types are selected, the required protocols for discovering and managing the selected device types

are added to the Discover Devices wizard. For example, if you select ESXi Host, SNMP Configuration and

WS-Man Configuration options are added to the wizard. The following table describes the fields

displayed in the Device Type Filtering window.

Field Description

Device Type Displays the device types that you can select to

discover and manage.

Required Protocol Displays the protocols that are required to discover

and manage the selected device types.
