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.
4 Launch the TFTP client on your computer and connect to the ZyWALL. Set the transfer
mode to binary before starting data transfer.
5 Use the TFTP client (see the example below) to transfer files between the ZyWALL and
the computer. The file name for the firmware is “ras”.
Note that the telnet connection must be active and the ZyWALL 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
ZyWALL to the computer, “put” the other way around, and “binary” to set binary transfer
mode.
40.5.6 TFTP Upload Command Example
The following is an example TFTP command:
tftp [-i] host put firmware.bin ras
Where “i” specifies binary image transfer mode (use this mode when transferring binary files),
“host” is the ZyWALL’s IP address, “put” transfers the file source on the computer
(firmware.bin – name of the firmware on the computer) to the file destination on the remote
host (ras - name of the firmware on the ZyWALL).
Commands that you may see in GUI-based TFTP clients are listed earlier in this chapter.
40.5.7 Uploading Via Console Port
FTP or TFTP are the preferred methods for uploading firmware to your ZyWALL. However,
in the event of your network being down, uploading files is only possible with a direct
connection to your ZyWALL via the console port. Uploading files via the console port under
normal conditions is not recommended since FTP or TFTP is faster. Any serial
communications program should work fine; however, you must use the Xmodem protocol to
perform the download/upload.
