This article describes how to resolve an issue where FortiSwitch configurations are lost following a firmware upgrade.
Scope
FortiSwitch.
Solution
By default, configuration changes on a FortiSwitch are saved automatically. However, if configurations are lost after an upgrade, it is important to verify the cfg-save setting.
In some cases, the cfg-save option may be set to manual, meaning that any configuration changes must be saved explicitly using the command:
execute cfg save
If the switch is upgraded without manually saving the changes, all unsaved configurations will be lost.
Example: Manual Configuration Setting:
config system global set cfg-save manual end
Recommended Solution: To ensure configuration changes are saved automatically and persist through upgrades, it is recommended to set cfg-save to automatic:
config system global set cfg-save automatic end
This setting ensures that all changes are saved automatically after each configuration modification, reducing the risk of losing configurations during an upgrade.
