Network Discovery
The following properties are in every Network Property Group: Property Purpose Hardcoded Default Setting

Actively ping Actively ping devices for discovery Off

names (the computer user names)

management
Off
Force ARP table read Force ARP table to be read Off
Accumulate IP Addresses Accumulate IP addresses instead of

Off
Allow IP addresses Set to Off when multiple servers
have the same IPv4 address that
you don’t want to see, for instance,
when you are using Network
Address Translation (NAT). Set to
On when you want to allow the
repeated IPv4 addresses to be
included.
On
Allow ICMP and SNMP Pinging and polling is turned off, so
devices will not be modelled. If the
device is already in the database,
Network Discovery will still poll and
ping the device for other reasons
(for example, to monitor device
attributes).
Although pinging and polling is
turned off, devices can still be
discovered by PDI and included in
the database.
Off
Device modeler interval Determines how frequently
Network Discovery updates your
view of the network. The device
modeler interval is not “on,” “off,” or
“inherit”, but rather “set” or
“inherit”. If the value is set, it is set to
a specific time.
