The video shows you how to configure High Availability on Cisco FTD 6.1. We will setup a pair of FTD device to create a HA pair. We will configure failover links and virtual MAC address. Failover test will be performed at the end using various failure scenarios. 
Part 2 of this video covers Interface Monitoring, Virtual MAC Address, and failover testings
  • High Availability (HA)
    • HA Failover Link
    • Stateful Link
  • Interfaces Monitoring
  • Virtual MAC Address
  • Failover Tests

Hi Metha,

When running a HA pair as in this setup can you still have the FTD appliances configured with redundant interfaces to separate switches? I am just thinking for some situations where there are two ISP connections but connected to two separate non VPC/VSS/Stacked switches. Do the redundant interfaces need to be configured prior to building HA pair?

Good question. We never tried this but couldn't imagine why it would not work as long as you have the same physical connection on both FTD. We sugguest building the HA pair first and see if the option to configure redundant interface is there.

On this video (HA Part 2) one of your appliances looks to have a redundant interface cabled for Outside whereas the other one is not cabled as such (at least in the diagram). Is your setup mirrored on each, and were redundant interfaces setup prior to building the HA Pair?

The redundant interface was setup in the previous lab prior to HA.
