34.5.5 TFTP File Upload
The ZyXEL Device also supports the uploading of firmware files 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 transfer the firmware
and the configuration file, follow the procedure shown next.

and 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.
the telnet client and accepts TFTP requests only from this address.
2 Put the SMT in command interpreter (CI) mode by entering 8 in Menu 24 – System
Maintenance.
3 Enter the command “sys stdio 0” to disable the console timeout, so the TFTP transfer
will not be interrupted. Enter “command sys stdio 5” to restore the five-minute console
timeout (default) when the file transfer is complete.
timeout (default) when the file transfer is complete.
4 Launch the TFTP client on your computer and connect to the ZyXEL Device. Set the
transfer mode to binary before starting data transfer.
5 Use the TFTP client (see the example below) to transfer files between the ZyXEL
Device and the computer. The file name for the firmware is “ras”.
Note that the telnet connection must be active and the ZyXEL Device in CI mode 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, “put” the other way around, and “binary” to set binary
transfer mode.
