This section provides technical background information on the topics discussed in this chapter.
39.8.1 FTP Command Line
This section shows some examples of uploading to or downloading files from the Switch using FTP
commands. First, understand the filename conventions.
39.8.2 Filename Conventions
The configuration file (also known as the romfile or ROM) contains the Zyxel factory default configuration
settings in the screens such as password, Switch setup, IP Setup, and so on. Once you have customized
the Switch’s settings, they can be saved back to your computer under a filename of your choosing.
ZyNOS (Zyxel Network Operating System sometimes referred to as the “ras” file) is the system firmware
and has a “bin” filename extension.
39.8.2.1 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.
