17.2.2 Backup Configuration Using TFTP
The Prestige 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.
Step 1.
Use telnet from your computer to connect to the Prestige and log in. Because TFTP does not
have any security checks, the Prestige records the IP address of the telnet client and accepts
TFTP requests only from this address.
Step 2.
Put the SMT in command interpreter (CI) mode by entering 8 in
Menu 24 – System
Maintenance
.
Step 3.
Enter command “sys stdio 0” to disable the SMT timeout, so the TFTP transfer will not be
interrupted. Enter command “sys stdio 5” to restore the five-minute SMT timeout (default)
when the file transfer is complete.
Step 4.
Launch the TFTP client on your computer and connect to the Prestige. Set the transfer mode to
binary before starting data transfer.
Step 5.
Use the TFTP client (see the example below) to transfer files between the Prestige 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 Prestige to the computer and “binary” to set
binary transfer mode.
17.2.3 TFTP Command Example
The following is an example tftp command:
TFTP [-i] host get rom-0 config.rom
Page 208 / 285

Firmware and Configuration Maintenance
where “i” specifies binary image transfer mode (use this mode when transferring binary files), “host” is the
Prestige IP address, “get” transfers the file source on the Prestige (rom-0 name of the configuration file on
the Prestige) to the file destination on the computer and renames it config.rom.
TFTP GUI Clients
The following table describes some of the fields that you may see in some TFTP GUI clients.
Table 17-3 General Commands for TFTP GUI Clients
COMMAND
DESCRIPTION
Host
Enter the IP address of the Prestige. 192.168.1.1 is the Prestige’s default IP address
when shipped.
Send/Fetch
Use “Send” to upload the file to the Prestige and “Fetch” to back up the file on your
computer.
Local File
Enter the path and name of the firmware file (*.bin extension) or configuration file (*.rom
extension) on your computer.
Remote File
This is the filename on the Prestige. The filename for the firmware is “ras” and for the
configuration file, is “rom-0”.
Binary
Transfer the file in binary mode.
Abort
Stop transfer of the file.
Refer to the
TFTP and FTP over WAN Will Not Work When
section to read about configurations that
disallow TFTP and FTP to work over WAN.
17.2.4 Backup Via Console Port
Backup configuration via console port by following the HyperTerminal procedure shown next. Procedures
using other serial communications programs should be similar.
Step 13.
Display menu 24.5 and enter “y” at the following screen.

17.3 Restore Configuration
This section shows you how to restore a previously saved configuration. Note that this function erases the
current configuration before restoring a previous back up configuration; please do not attempt to restore
unless you have a backup configuration file stored on disk.
FTP and TFTP are the preferred methods for restoring your current computer configuration to your Prestige
since FTP and TFTP are faster. Please note that you must restart the system after the file transfer is
complete.
WARNING!
DO NOT INTERUPT THE FILE TRANSFER PROCESS AS THIS MAY
PERMANENTLY DAMAGE YOUR PRESTIGE. WHEN THE RESTORE
CONFIGURATION PROCESS IS COMPLETE, THE PRESTIGE WILL
AUTOMATICALLY RESTART.
17.3.1 Restore Using FTP or TFTP
For details about backup using (T)FTP please refer to earlier sections on FTP and TFTP file upload in this
chapter.
** Backup Configuration completed. OK.
