Adding and editing a device in NMIS8 is very easy, there are only three things which MUST be included, these are a name for the node (this does not need to be IP/DNS resolvable), a hostname or IP address for the device (this does need to be IP/DNS resolvable) and you need to provide an SNMP community string. You can basically use defaults for everything else.
