Hello @CEMS ,

Can you check if the interfaces you're trying to configure might already be part of another trunk group or not.

• Error: Static/Sticky MAC entry (id=5) exists in the trunk member port port5 !!!. Also this warning change when I try different ports for example sometimes  port4,port1 so when I check the static address and sticky Mac I don’t use

On the FortiGate,  the Network > Interfaces page, you can see the FortiGate interface connected to the FortiSwitch unit. The GUI indicates Dedicated to FortiSwitch in the IP/Netmask field. There's a column to the very far right that has clickable references.
