How to assign VLANs to a MCLAG-trunk?

[Thor-Egil]

Hi,

I have a two-tier MCLAG-topology with 2x1048E switches in tier 1 and several MCLAG Peer Groups in tier 2. The switches are managed by Fortigates in HA-setup. Now I want to connect multi-homed servers to the tier1-switches and I have created trunk interfaces with MCLAG and active-active LACP via the switch-controller on the Fortigate.  The member ports are defined with 1 port from each switch in the MCLAG. What is the recommended way to assign VLANs to the trunk-interface? Should I assign the VLANs via the Trunk-tab or directly to the member-ports in the Interface-tab? With both methods work?

Assign the VLANs to the Trunk on the Trunk-tab
