Configuration | config | *.cfg | This is the configuration filename on the |
File |
|
| Switch. Uploading the config file replaces the |
|
|
| specified configuration file system, including |
|
|
| your Switch configurations, |
|
|
| data (including the default password), the |
|
|

33.8.1.1 Example FTP Commands
ftp> put firmware.bin ras
This is a sample FTP session showing the transfer of the computer file "firmware.bin" to the Switch.
ftp> get config config.cfg
This is a sample FTP session saving the current configuration to a file called “config.cfg” on your computer.
If your (T)FTP client does not allow you to have a destination filename different than the source, you will need to rename them as the Switch only recognizes “config” and “ras”. Be sure you keep unaltered copies of both files for later use.
Be sure to upload the correct model firmware as uploading the wrong model firmware may damage your device.
33.8.2 FTP Command Line Procedure
1Launch the FTP client on your computer.
2Enter open, followed by a space and the IP address of your Switch.
3Press [ENTER] when prompted for a username.
4Enter your password as requested (the default is “1234”).
5Enter bin to set transfer mode to binary.
