Chapter 21 Tools Table 77 General Commands for GUI-based FTP Clients COMMAND DESCRIPTION Transfer Type Transfer files in either ASCII (plain text format) or in binary mode. Initial Remote Directory Specify the default remote directory (path). Initial Local Directory Specify the default local directory (path). 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. 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 Enter command "sys stdio 0" to disable the management idle timeout, so the 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. 3 Launch the TFTP client on your computer and connect to the ZyXEL Device. Set the transfer mode to binary before starting data transfer. 4 Use 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" (romzero, 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 228 FSG2200HNU User's Guide
