The fast saving mode is suitable for environments where the power supply is stable. The safe mode is preferred in environments where a stable power supply is unavailable or remote maintenance is involved.

Follow these steps to save the current configuration:

To do…

Use the command…

Remarks

Save the current configuration to

 

the specified file, but the

save file-url

configuration file will not be set as

 

the file for the next startup

 

 

 

Save the current configuration to

 

the root directory of the storage

save [ safely ] [ backup main ]

medium and specify the file as the

[ force ]

startup configuration file to be used

 

at the next system startup

 

 

 

Required

Use either command Available in any view.

NOTE:

•The configuration file must have the .cfg extension.

•The execution of the save [ safely ] and save [ safely ] main commands has the same effect: The system will save the current configuration and specify the configuration file as the main startup configuration file to be used at the next system startup.

•During the execution of the save [ backup main ] command, the startup configuration file to be used at the next system startup may be lost if the switch reboots or the power supply fails. The switch will boot with the null configuration, and after the switch reboots, you will need to re-specify a startup configuration file for the next system startup (see “Specifying a startup configuration file to be used at the next system startup”).

Setting configuration rollback

Configuration rollback

Configuration rollback allows you to revert to a previous configuration state based on a specified configuration file. The specified configuration file must be a valid .cfg file generated by using either the backup function (manually or automatically) or the save command, or, if a configuration file is generated by another switch, the configuration file must comply with the format of the configuration file on the current switch. HP recommends that you use the configuration file that is generated by using the backup function (manually or automatically). Configuration rollback can be applied in the following situations:

•Running configuration error. Rolling back the running configuration to a correct one is needed.

•The application environment has changed and the switch has to run in a configuration state based on a previous configuration file without being rebooted.

Before setting configuration rollback, perform the following steps:

1.Specify the filename prefix and path for saving the running configuration.

2.Save the running configuration with the specified filename (filename prefix + serial number) to the specified path. The running configuration can be saved automatically or manually.
