20.2.3 Backup Configuration Using TFTP

The ZyAIR supports the up/downloading of the firmware and the configuration file using
TFTP (Trivial File Transfer Protocol) over Ethernet.
To use TFTP, your computer must have both telnet and TFTP clients. To backup the
configuration file, follow the procedure shown next:
1 Use telnet from your computer to connect to the ZyAIR and log in. Because TFTP does
not have any security checks, the ZyAIR records the IP address of the telnet client and
accepts TFTP requests only from this address.
2 Put the SMT in command interpreter (CI) mode by entering 8 in Menu 24 – System
Maintenance.
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.
4 Launch the TFTP client on your computer and connect to the ZyAIR. Set the transfer
mode to binary before starting data transfer.
5 Use the TFTP client (see the example below) to transfer files between the ZyAIR 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 ZyAIR
to the computer and "binary" to set binary transfer mode.

20.2.4 Example: TFTP Command

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 ZyAIR IP address, "get" transfers the file source on the ZyAIR (rom-0 name of
the configuration file on the ZyAIR) to the file destination on the computer and renames it
config.rom.
The following table describes some of the fields that you may see in third party TFTP clients.
