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.
Use telnet from your computer to connect to the ZyXEL Device and log in. Because
1
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.
Enter command "sys stdio 0" to disable the management idle timeout, so the
2
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.
Launch the TFTP client on your computer and connect to the ZyXEL Device. Set
3
the transfer mode to binary before starting data transfer.
Use the TFTP client (see the example below) to transfer files between the ZyXEL
4
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.
TFTP Command Configuration Backup Example
The following is an example TFTP command:
tftp [-i] host get rom-0 config.rom
where "i" specifies binary image transfer mode (use this mode when transferring
binary files), "host" is the ZyXEL Device IP address, "get" transfers the file source

DESCRIPTION
Transfer files in either ASCII (plain text format) or in binary
mode.
Specify the default remote directory (path).
Specify the default local directory (path).
