Table 20. 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 Conguration
ICMP is used to by discovery engine to determine whether or not any device has a specied 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 Conguration Options to congure
the ICMP parameters.
NOTE: ICMP ping is optional for OpenManage Essentials 2.3. The ICMP Conguration is displayed based on the selection
of
Skip ICMP ping during discovery under Settings → Discovery Settings → Skip ICMP ping during discovery.

ICMP Conguration Options
Table 21. ICMP Conguration Options
Field Description
Timeout (milliseconds) Species 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 specied IP
address.
Retries (attempts) Species the maximum number of additional times that the
discovery engine will send an ICMP request if the rst 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 Conguration
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 Conguration Options to
discover and inventory servers, storage devices, and other network devices.
