Unique MAC Address

Starting from 4.3.0 release, virtual Edges support a unique MAC address feature on a High Availability interface.

Instead of generating a common or shared virtual MAC address when in HA, this feature uses the physical MAC address for hardware Edges and the assigned MAC address for virtual Edges.

Important: On a customer enterprise using HA Edges and VMware vSwitches: where possible, MAC learning should be configured on all vSwitches. MAC learning is available on vSphere version 6.7 and later. If MAC learning is configured on all vSwitches, Unique MAC Address is not required. However if the vSwitches do not have MAC learning configured, Unique MAC Address is required on the HA Edge.
