Chapter 23 Firmware and Configuration File Maintenance

215

To transfer the firmware and the configuration file, follow these examples:

1 Launch the FTP client on your computer.

2 Enter “open” and the IP address of your ZyAIR.  

3 Press [ENTER] when prompted for a username.

4 Enter “root” and your SMT password as requested. The default is 1234.

5 Enter “bin” to set transfer mode to binary.

6 Use “put” to transfer files from the computer to the ZyAIR, e.g., put firmware.bin ras 

transfers the firmware on your computer (firmware.bin) to the ZyAIR and renames it 
“ras”. Similarly “put config.rom rom-0” transfers the configuration file on your computer 
(config.rom) to the ZyAIR and renames it “rom-0”. Likewise “get rom-0 config.rom” 
transfers the configuration file on the ZyAIR to your computer and renames it 
“config.rom.” See earlier in this chapter for more information on filename conventions.

7 Enter “quit” to exit the FTP prompt.

More commands that you may find in third party FTP clients are listed earlier in this chapter.

The ZyAIR also supports the up/downloading of the firmware and the configuration file 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 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.
