Description	This article describes an issue with a corrupt FortiLink interface. It is impossible to configure FortiLink and it shows the error 'Failed to get FortiLink interface data'. The issue is the missing configuration which caused this error:
Scope	FortiOS.
Solution	To resolve this issue, it is necessary to create a new FortiLink interface under hard-switch by going to Network -> Interface -> Create New -> Type hardware Switch. After that, it is necessary to enable FortiLink on that interface by running the following commands on CLI: config sys interface     edit fortilink2         set fortilink enable end Once enabled, it will display a new FortiLink interface as the below screenshot shows it and that can be used for FortiSwitch: A similar interface can be seen under Wifi & Switch Controller -> FortiLink Interface: Now, it should be possible to connect a new FortiSwitch using the new Fortilink2 interface.
