Hello again pemasirid,

I found this solution. Can you tell me if it helps, please?

To configure a dual-homed FortiGate HA setup with FortiSwitches using LACP, follow these steps:

1. Configure FortiLink Interface: Ensure that the FortiLink interface is configured on both FortiGate units. This interface will manage the FortiSwitches.
   
   
2. Configure LACP on FortiSwitches: On each FortiSwitch, configure LACP groups for the ports connecting to the FortiGate units. This is done using the `config switch trunk` command in the FortiSwitch CLI.
   
   
3. Separate LACP Groups: Each connection from the FortiGate to the FortiSwitch should be in a separate LACP group. This means you will have two LACP groups per FortiSwitch, one for each FortiGate.
   
   
4. FortiGate Configuration: On the FortiGate, ensure that the FortiLink interface is set to use LACP. This can be done by setting the `set lacp-mode` to `active` or `passive` under the FortiLink interface configuration.
   
   
5. Verify Configuration:
   - Use the `get system ha status` command on the FortiGate to verify HA status.
   - Use the `execute switch-controller get-conn-status` command to check the FortiLink state.
   
   
6. Testing: Test failover scenarios to ensure that the HA and LACP configurations are working as expected.

If you need specific command examples or further assistance, please provide more details about your current configuration.
