When the boot using themain and backup configuration files fails, the system boots using the defaultconfiguration file. If the boot using the default configuration file fails, the systemboots without loading a configuration file. Firewalls of different vendors havedifferent default configuration file names. The main/backup attribute configurationon the default configuration file is the same as that on common configuration files.At present, the name of the default configuration file of the F1000-E firewall isstartup.cfg.Note that:z The configuration files for system boot can be type M, B and default configurationfile of type N. The non-default configuration files of type N (that is, neither M nor B)cannot be used for system boot.z You can modify the name of a configuration file using commands after theapplication boots. You cannot modify the type of the default configuration file, butyou can modify the file type of type M, B and N configuration files using commandsafter the application boots.z There is only one file of the same type (M, or B) on the CF card.
