Configuration Backup Using GUI-based FTP Clients

The following table describes some of the commands that you may see in GUI-

based FTP clients.

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).
