There are many ways that you can test a failover configuration of Core HA or Edge HA. These tests may include power-cycling, HA peer device reboot, or any number of network connection failure scenarios (routers, switches, cables).

Your failover test should at least satisfy the basic requirements that ensure the HA deployment recovers as expected.

The simplest test is to perform an orderly reboot of a peer device (Core or Edge) that is one half of an HA configuration.
