Adding Fortiswitch to existing FortiGate

I tried to find on the forum but did not succeed.

Just wondering, is it possible to add a FortiSwitch to the existing FortiGate where the VLAN interfaces are living under an interface on the FortiGate? Normally, I would take a fresh FGT and a FTS and build the VLAN interfaces under FortiSwitch VLANs, but those already exist on the FortiGate. So, I'm just looking for some migration steps to replace the old none Fortinet switch with the FortiSwitch with FortiLink.

Hello,

Thank you for reaching out. I believe you cannot join swtich using that vlan to fortilink while the vlan interface is configured on a different interface on the fortigate. Is there a reason not to create the vlan interface under fortilink then join the switch using that vlan. I know you will have to delete the vlan interface first to free it up from the other interface in order to be able to add it under fortilink which creates an issue if you have production network already using this vlan.

Thank you,

That's true... Juts wondering if it will be possible to crate vlan interfaces in the fortiswitch, remove the vlan interfaces on the fortigate and then add the fortiswitch to the fortigate via FortiLink

Hi @ZafirFX,

Once you add FortiSwitch to FortiGate, it will retrieve the configuration from FortiGate. Hence, VLANs should be configured on the FortiGate. The old switch was connected to which interface? Is it not a fortilink? fortilink can be enabled on any physical interface using the following commands:

config system interface

edit <>

set fortilink enable

end
