(3) Notes
-
If there is no definition file, the Internet protocol version selection is invalid. In this case, IPv4=ON and IPv6=OFF are assumed at both the FTP server and the FTP client.
-
If IPv4=OFF and IPv6=OFF are defined at the FTP server, it is considered that there is no definition. In this case, IPv4=ON and IPv6=OFF are assumed.
-
If IPv4=OFF and IPv6=OFF are defined at the FTP client, the definition is assumed not to exist. In this case, IPv4=ON and IPv6=OFF are assumed.
