Failover tracking interfaces show Unknown (Waiting)

On our ASA 5545 Cluster, Software Version 9.1(4), the Failover Tracking Interfaces show Unknown (Waiting).  When the ethernet cable is pulled on one of the tracking interfaces of the active ASA, failover does not happen.

Failover tracking interfaces show Unknown (Waiting)

It was pointed out to me by David White in a different thread:

You are missing the "Standby IPs" on each interface.  This is required for Failover interface monitoring.  Once you assign Standby IPs, the "show failover" output will display them on the Standby unit, and the interfaces will transition from "Waiting" to "Normal".

This was the problem.
