Chapter 21 Tools 1 Use telnet from your computer to connect to the P-792H v2 and log in. Because TFTP does not have any security checks, the P-792H v2 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 P-792H v2. Set the transfer mode to binary before starting data transfer. 4 Use the TFTP client (see the example below) to transfer files between the P-792H v2 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 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 P-792H v2 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 P-792H v2 IP address, "get" transfers the file source on the P-792H v2 (rom-0, name of the configuration file on the P-792H v2) to the file destination on the computer and renames it config.rom. Configuration Backup Using GUI-based TFTP Clients The following table describes some of the fields that you may see in GUI-based TFTP clients.
