1-3Modes in saving the configurationz Fast saving mode. This is the mode when you use the save command without the safely keyword.The mode saves the file quicker but is likely to lose the original configuration file if the switchreboots or the power fails during the process.z Safe mode. This is the mode when you use the save command with the safely keyword. The modesaves the file slower but can retain the original configuration file in the switch even if the switchreboots or the power fails during the process.When you use the save safely command to save the configuration file, if the switch reboots or thepower fails during the saving process, the switch initializes itself in the following two conditions when itstarts up next time:z If a configuration file with the extension .cfg exists in the Flash, the switch uses the configurationfile to initialize itself when it starts up next time.z If there is no .cfg configuration file in the Flash, but there is a configuration file with theextension .cfgbak (backup configuration file containing the original configuration information)or/and a configuration file with the extension .cfgtmp (temporary configuration file containing thecurrent configuration information) in the Flash, you can change the extension .cfgbak or .cfgtmpto .cfg using the rename command. The switch will use the renamed configuration file to initializeitself when it starts up next time.For details of the rename command, refer to the File System Management part of the manual.Three attributes of the configuration filez Main attribute. When you use the save [ [ safely ] [ main ] ] command to save the currentconfiguration, the configuration file you get has main attribute. If this configuration file alreadyexists and has backup attribute, the file will have both main and backup attributes after execution ofthis command. If the filename you entered is different from that existing in the system, thiscommand will erase its main attribute to allow only one main attribute configuration file in theswitch.z Backup attribute. When you use the save [ safely ] backup command to save the currentconfiguration, the configuration file you get has backup attribute. If this configuration file alreadyexists and has main attribute, the file will have both main and backup attributes after execution ofthis command. If the filename you entered is different from that existing in the system, thiscommand will erase its backup attribute to allow only one backup attribute configuration file in theswitch.z Normal attribute. When you use the save cfgfile command to save the current configuration, theconfiguration file you get has normal attribute if it is not an existing file. Otherwise, the attribute isdependent on the original attribute of the file.
