Redundancy when connecting two switches to FTD??

[JustTakeTheFirstStep]

FTD is operating in ASA mode.

Unfortunately, FTD does not support redundant interfaces.

Any ideas on a design that provides redundancy when connecting two SWs to an FTD?

@JustTakeTheFirstStep if the switches are a stack or using StackWise Virtual or VSS or VPC then you can connect FTD interfaces within the same EtherChannel to separate switches in the VSS/vPC or VSL.
