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.
Table 22. Device Type Filtering
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.
ICMP Configuration
ICMP is used to by discovery engine to determine whether or not any device has a specified IP address. The discovery engine sends
out a request and waits until the 'timeout' period to receive a reply. If a device is busy doing other things, it may not reply to an
ICMP request as quickly as it would under low-load conditions. If no device has been assigned to the IP address being tested by the
discovery engine, there will be no response at all. If no reply is received within the 'timeout' period, the discovery engine will repeat
the request up to 'Retries' times (waiting, each time, for the 'timeout' period to expire). See
ICMP Configuration Options to
configure the ICMP parameters.

ICMP Configuration Options
Table 23. ICMP Configuration Options
Field Description
Timeout (milliseconds) Specifies the maximum number of milliseconds the discovery
engine waits for a reply after issuing an ICMP request. The
default timeout period is 1000 milliseconds. A higher value allows
more time to receive responses from busy devices, but also
means more wait time if there is no device with a specified IP
address.
Retries (attempts) Specifies the maximum number of additional times that the
discovery engine will send an ICMP request if the first request
times out. A device may have been too busy to respond to an
earlier ICMP request, but may be able to respond to a
subsequent request. If there is no device with the IP address
being used, retries will also timeout, so the retry count should be
a small number. The default value is 1.
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 SNMP Configuration Options to
discover and inventory servers, storage devices, and other network devices.
