Automatic Import of Configuration Files
When enabled, NSM by default automatically deletes oldest versions of config files to
accommodate newer versions of the config files that are being imported. You can set a
system preference for the maximum number of config file versions to be preserved. The
default is 25 versions. The Config File Manager can automatically import config files from
managed Junos OS-based devices when configuration changes are committed on these
devices, enabling NSM to have different versions of the device configuration. You can
enable or disable the automatic import of config files and track those devices on which
the feature is enabled. You can also see status of the config file versions.
