How to save exit and delete on an H3C core switch

On an H3C switch, use save to store configurations, return or Ctrl+Z to exit views, and undo commands or bootrom options to delete configurations or aliases.

Exiting Views

• Return to user view from system or interface view using return or pressing Ctrl+Z .
• Abort changes without saving using the abort command, which discards uncommitted configuration lines .
• Exit from TCL or Python shell views with tclquit or exit() respectively .

Saving Configurations

• To save the current configuration to the startup file, use the command:

  CodeCopysave This ensures that all changes persist after a reboot .

• You can also save the output of display commands to a file using:

  CodeCopydisplay > filename where filename is the target file name on the switch .

Deleting Configurations or Aliases

• Delete a command alias with:

  CodeCopyundo alias System-defined aliases cannot be deleted .

• Restore factory settings (deletes all configurations) by entering bootrom mode during startup with Ctrl+B and selecting restore factory settings .
• Delete specific configuration files in flash memory via bootrom or CLI file management commands if needed .

Additional Tips

• Always confirm changes with display current-configuration before saving.
• Use quit to exit interface or port views if you do not want to return to user view immediately.
• For VLAN or interface changes, ensure you save after configuration to avoid losing settings on reboot . By following these commands, you can efficiently manage H3C switch configurations, safely exit views, and remove unnecessary aliases or settings.
