Use telnet from your computer to connect to the P-792H v2 and log in. Because
1
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.
Enter command "sys stdio 0" to disable the management idle timeout, so the
2
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.
Launch the TFTP client on your computer and connect to the P-792H v2. Set the
3
transfer mode to binary before starting data transfer.
Use the TFTP client (see the example below) to transfer files between the P-792H
4
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.
