The configuration is the customized set of parameters that you have selected to run on the switch. As you make configuration changes, the new settings are stored in run-time memory. Settings that are stored in run-time memory are not retained by the switch when the switch is rebooted. To retain the settings and have them loaded when you reboot the switch, you must save the configuration to nonvolatile storage.
The switch can store multiple user-defined configuration files, each with its own filename. By default, the switch has two prenamed configurations: a primary and a secondary configuration. When you save configuration changes, you can select to which configuration you want the changes saved or you can save the changes to a new configuration file. If you do not specify a filename, the changes are saved to the configuration file currently in use. Or if you have never saved any configurations, you are asked to save your changes to the primary configuration.
Note
Configuration files have a .cfg file extension. When you enter the name of the file in the CLI, the system automatically adds the .cfg file extension.If you have made a mistake or you must revert to the configuration as it was before you started making changes, you can tell the switch to use the backup configuration on the next reboot.
Each filename must be unique and can be up to 32 characters long. Filenames are also case sensitive. For information about filename restrictions, see the specific command in the ExtremeXOS v33.1.1 Command Reference Guide .

Note
When a switch boots up after executing this command, examine the log to determine if a subsequent save and a reboot of the switch or slot is necessary for the configuration to be correctly applied.Note
If the switch is rebooted while in the middle of saving a configuration, the switch boots to factory default settings if the previously saved configuration file is overwritten. The configuration that is not in the process of being saved is unaffected.
