Chapter 24 Firmware and Configuration File Maintenance

5Use 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).

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 and “binary” to set binary transfer mode.

24.2.3 Example: TFTP Command

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 on the ZyXEL Device (rom-0 name of the configuration file on the ZyXEL Device) to the file destination on the computer and renames it config.rom.

The following table describes some of the fields that you may see in third party TFTP clients.

24.3 Restore Configuration

You can restore the configuration via FTP or TFTP to your ZyXEL Device. The preferred method is FTP. Note that this function erases the current configuration before restoring the previous backup configuration; please do not attempt to restore unless you have a backup configuration stored on disk. To restore configuration using FTP or TFTP is the same as uploading the configuration file, please refer to the following sections on FTP and TFTP file transfer for more details. The ZyXEL Device restarts automatically after the file transfer is complete.
