does not match, the Prestige will disconnect the Telnet session immediately.
There is a SMT console session running.

11.2.2 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.
