More commands (found in GUI-based FTP clients) are listed in this chapter.
Refer to Section 19.1.2 on page 180 to read about configurations that disallow
TFTP and FTP over WAN.
TFTP File Upload
The device also supports the uploading of firmware files 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 transfer
the firmware and the configuration file, follow the procedure shown next.
1
Use telnet from your computer to connect to the device and log in. Because TFTP
does not have any security checks, the device records the IP address of the telnet
client and accepts TFTP requests only from this address.
2
Enter the command “sys stdio 0” to disable the management idle timeout, so the
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.
3
Launch the TFTP client on your computer and connect to the device. Set the
transfer mode to binary before starting data transfer.
4
Use the TFTP client (see the example below) to transfer files between the device
and the computer. The file name for the firmware is “ras”.
Note that the telnet connection must be active and the device 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
