High Availability - HA Heartbeat Backup
If HA1 and HA1-backup are configured with data plane ports then Heartbeat backup is needed. If Management port is used as HA1 bkup then Heartbeat backup is not needed.
Why, though? What's the reason that using management ports for a Control Link makes Heartbeat Backup not needed, or put another way, why does not using a management ports for a Control Link make Heartbeat Backup advantageous or necessary?
@ChrisSutton Great question Chris.
