35.4.4 TFTP File Upload

The ZyXEL Device also 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 transfer the firmware
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.
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 SMT timeout, so the TFTP transfer will
not be interrupted. Enter command "sys stdio 5" to restore the five-minute SMT 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" and the configuration file is
"rom-0" (rom-zero, not capital o).
Note that the telnet connection must be active and the SMT 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.
