Back up the configuration before deleting any part of the configuration. Deleted items cannot be recovered unless you upload a backup copy of the previous configuration. See “Backups” and “Restoring a previous configuration”. |
If you do not know where your configuration refers to the entry that you want to delete, to find the references, you can download a backup of the configuration and use a plain text editor to search for the entry’s name. |
Predefined entries included with the firmware cannot be deleted. |
