A configuration file must use
.cfg
as its extension name and the startup configuration file must be saved
in the root directory of the storage medium.
Backing Up the Startup Configuration File
The backup function allows you to copy the startup configuration file to be used at the next startup from
the device to the TFTP server.
The backup operation backs up the main startup configuration file to the TFTP server for devices
supporting main and backup startup configuration files.
Follow the step below to back up the startup configuration file to be used at the next startup:

main and backup startup configuration files, you can choose to delete either the main, the backup, or

the startup configuration file to NULL.
