If the li-local-save command is enabled on the BOF, saving the LI configuration is highly recommended after every configuration mode change.
The main configuration file (default: config.cfg) determines the system bootup configuration mode, specifically from the command line configure system management-interface configuration-mode. When the administrator executes the configuration mode change, the LI configuration file format remains as the last saved format until an admin save li command is executed. For example, when migrating from classic to model-driven configuration mode, the LI configuration in the file li.cfg remains in the classic format until the admin save li command is executed to update the file format to a model-driven format.
If the LI configuration fails to boot because the admin save li command is not performed immediately after a configuration mode migration, both log 99 and console dump inform the LI configuration field to load because the LI format does not match the primary configuration format file. The format of both the li.cfg file and the main configuration must match. To recover, the main configuration must be rolled back to the previous configuration mode to match the li.cfg file saved format (as indicated by console dump or log 99), and then rebooted.
It is important not to perform a save li command when there is a configuration mode mismatch between the main configuration (default config.cfg) file and the li.cfg file. Saving the li.cfg file creates a new file without any configuration. The previously generated li.cfg file is archived as li.cfg.1 file. If a save li command is accidentally executed, perform the following steps:
Roll back to the previous configuration mode in which the li.cfg.1 file is saved (as indicated by console dump or log 99).
Reboot the system.
Restore the li.cfg.1 file using the exec li.cfg.1 command.
