FG HA LACP Switch clustering.

 

I'd like to know what is the best practice for FG HA Switch clustering.
How can I configure the LACP on switch with separate LACP group (Solution A)  or I can configure the same LACP group (Solution B) .

PS. Switch is a Cisco CoreSwitch and connected the LAN network.

I don't think Solution B would work. One FGT needs to terminate all LAG/LACP members from the switch.

Can we configure this command?
config system interface
    edit port1_port2
        set lacp-ha-slave disable
    next

end

Ok, I didn't know it's possible. I don't see much benefit of it though compared to have two separate LAGs and the switch distributes the same set of VLANs to both LAGs.
