– By default, the interval at which the system saves the configuration file is 0
seconds, indicating that the system does not save the configuration file
automatically.
– After automatic configuration saving is enabled, the default interval is 30 minutes
if time is not specified.
l Save the current configuration immediately.
– Run:
save [ all ] [ configuration-file ]
The current configuration is saved.
The configuration file name extension must be .cfg or .zip, and the system startup
configuration file must be saved in the root directory of the storage device.
If you modify the current configuration and want to use the modified configuration as
the next startup configuration, run the save command to save the new configuration to
the storage device.
The save all command saves all the current configurations to the default directory,
including the configurations of the boards that are not running on the router.

7.2.3 Clearing a Configuration File
You can clear the configuration file that has been loaded to a device.
Context
The configuration file needs to be cleared in the following cases:
l The system software does not match the configuration file after the router has been
upgraded.
l The configuration file is destroyed or an incorrect configuration file has been loaded.
Procedure
l Run the reset saved-configuration command to clear the currently loaded configuration
file.
– If the configuration file of the router used for the current startup is the same as that used
for the next startup, running the reset saved-configuration command will clear both
the configuration files. The router will uses the default configuration file for the next
startup.
– If the configuration file of the router used for the current startup is different from that
used at the next startup, running the reset saved-configuration command will clear the
configuration file used for the current startup.
– If the configuration file of the router used for the current startup is empty, the system
will prompt you that the configuration file does not exist after you run the reset saved-
configuration command.
If you do not run the startup saved-configuration configuration-file command to specify
a new correct configuration file, or do not run the save command to save the configuration
file after the configuration file is cleared, the router will use the default configuration file
at the next startup.
