More commands (found in GUI-based FTP clients) are listed earlier in this chapter.
12.4.5 TFTP File Upload
The ExpWave 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.
Step 1. Use telnet from your computer to connect to the ExpWave and log in. Because TFTP does not have any
security checks, the ExpWave 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 the command “sys stdio 0” to disable the console timeout, so the TFTP transfer will not be
interrupted. Enter “command sys stdio 5” to restore the five-minute console timeout (default) when the file
transfer is complete.
Step 4. Launch the TFTP client on your computer and connect to the ExpWave. 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 ExpWave and the computer.
The file name for the firmware is “ras”.
Note that the telnet connection must be active and the ExpWave 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 ExpWave to the computer, “put” the other way around, and “binary” to set
binary transfer mode.
