20.4.4 TFTP File Upload

The ZyAIR also 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 transfer the firmware
and 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 the 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 firmware is "ras" and 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, "put" the other way around, and "binary" to set binary transfer mode.
