Figure 140   FTP Session Example of Firmware File Upload

More commands (found in GUI-based FTP clients) are listed earlier in this chapter.

Refer to

to read about configurations that disallow TFTP and FTP 

over WAN.

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 UNIX, use “get” to transfer from the device 
to the computer, “put” the other way around, and “binary” to set binary transfer mode.
