This article describes how to troubleshoot issues with FortiSwitch where the ports are partially or fully greyed out on the FortiGate GUI under Wi-Fi and Switch Controller -> Managed Switch Tab.
Solution
1) From GUI, the switch has last 26 ports greyed out and is not listed as a part of FortiSwtch ports in both GUI and CLI.
2) When seeing the available ports in the CLI of the FortiGate only the first 26 ports are listed.
6) Delete FortiSwitch from managed switch list of the FortiGate. Note that the switch config will also get deleted.
7) Manually add FortiSwitch using its serial number under Wi-Fi & Switch controller > Managed switch and select 'Create New'.
# config switch-controller managed-switch S448DNTF0-----13) Run the below FortiLink debug to check for any errors while FortiGate checks for the port properties of the switches.
