Technical Tip: How to reactivate a FortiSwitch managed by FortiGate

[Nishtha_Baria]

Description	This article describes how to reset and then reactivate a FortiSwitch managed by FortiGate.
Scope	FortiGate.
Solution	When a reset is performed, the configuration under FortiGate’s Managed FortiSwitch is still present even though the FortiSwitch has been reset. As a result, trying to reactivate the FortiSwitch on FortiGate does not work. To get rid of the configuration on the FortiGate side, follow the steps below: Factory Reset the FortiSwitch. On FortiGate, go to Wifi & Switch Controller -> Managed Switch -> select Authorization -> Deauthorize. From the CLI: config switch-controller managed-switch     edit <switch-serial-number>         set fsw-wan1-admin disable end Next, 'right-click' on the same FortiSwitch and then select ‘Delete’. From the CLI: config switch-controller managed-switch     edit <switch-serial-number>         set fsw-wan1-admin disable end The above steps will ensure that all settings related to the FortiSwitch are reset on FortiGate and can then be registered/authorized again on FortiGate.
