25.7.3 Configuration Backup Using GUI-based FTP Clients
The following table describes some of the commands that you may see in GUI-based FTP
clients.
25.7.4 Backup Configuration Using TFTP
The ZyXEL Device supports the up/downloading of the firmware and the configuration file
using TFTP (Trivial File Transfer Protocol) over LAN. Although TFTP should work over
WAN as well, it is not recommended.
To use TFTP, your computer must have both telnet and TFTP clients. To backup the
configuration file, follow the procedure shown next.
1 Use telnet from your computer to connect to the ZyXEL Device and log in. Because
TFTP does not have any security checks, the ZyXEL Device records the IP address of the
telnet client and accepts TFTP requests only from this address.
2 Enter command “ sys stdio 0 ” to disable the management idle timeout, so the TFTP
transfer will not be interrupted. Enter command “ sys stdio 5” to restore the five-
minute management idle timeout (default) when the file transfer is complete.
3 Launch the TFTP client on your computer and connect to the ZyXEL Device. Set the
transfer mode to binary before starting data transfer.
4 Use the TFTP client (see the example below) to transfer files between the ZyXEL Device
and the computer. The file name for the configuration file is “ rom-0 ” (rom-zero, not
capital o).
Note that the telnet connection must be active before and during the TFTP transfer. For details
on TFTP commands (see following example), please consult the documentation of your TFTP
client program. For UNIX, use “
get ” to transfer from the ZyXEL Device to the computer and
“binary” to set binary transfer mode.
