Backup Configuration Using TFTP
The P-79X 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.
Use telnet from your computer to connect to the P-79X and log in. Because TFTP does not have any
1
security checks, the P-79X records the IP address of the telnet client and accepts TFTP requests
only from this address.
Enter command "sys stdio 0" to disable the management idle timeout, so the TFTP transfer will
2
not be interrupted. Enter command "sys stdio 5" to restore the five-minute management idle
timeout (default) when the file transfer is complete.
Launch the TFTP client on your computer and connect to the P-79X. Set the transfer mode to binary
3
before starting data transfer.
Use the TFTP client (see the example below) to transfer files between the P-79X and the computer.
4
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-79X 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
