Flash File System Settings

Why use flash file system:
In old switch system, the firmware, configuration and log information are saved in a flash with fixed addresses and
size. This means that the maximum configuration file can only be 2Mb, and even if the current configuration is only
40Kb, it will still take up 2Mb of flash storage space. The configuration file number and firmware numbers are also
fixed. A compatible issue will occur in the event that the configuration file or firmware size exceeds the originally
designed size.
Flash File System in our system:
The Flash File System is used to provide the user with flexible file operation on the Flash. All the firmware,
configuration information and system log information are stored in the Flash as files. This means that the Flash
space taken up by all the files are not fixed, it is the real file size. If the Flash space is enough, the user could
download more configuration files or firmware files and use commands to display Flash file information, rename file
names, and delete it. Furthermore, the user can also configure the boot up runtime image or the running
configuration file if needed.
In case the file system gets corrupted, Z-modem can be used to download the backup files directly to the system.
