Recommended cabling for FTD not in HA

[Chuck Reimer]

We are deploying 2110 FTD's for L2L connectivity and had a question on the best cabling setup. Our current Internet and DMZ switches are stacked which we are moving away from this setup. What would be the best cabling setup to remove any SPOF with two different switches in play?

@Chuck Reimer Do you want multiple FTD's acting as VPN concentrators but not configured as an HA pair? This can be achieved with a route based VPN or defining multiple peer VPN (primary/secondary). Can you elaborate a bit more please?

@Rob Ingram Single device. More from a switch redundancy point of view. Our network team is breaking the stack so they can do upgrades without affecting all devices connected. So when they upgrade switch1 we would want our single device active regardless of which switch is up/down. We used port-channels before but I don't think this is an option now. Is our only option is deploying in HA pair?
