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
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.
