AWS HA Setup

Tried to work through the horribly fragmented documentation, but I have a quick question on setting up HA in AWS:

 

Is it still suggested to swap the mangement interface when deploying the HA model?  From the HA documentation section, it sounds like eth0 needs to be the management interface which is in contradiction to the other documentation in there.

Re: AWS HA Setup

If you are doing HA in AWS I take it there is no plan to use a load balancer. That being the case then the interface swap is not needed. The interface swap is so that the VM-Series can receive traffic from a load balancer in AWS because it has to be sent to the first ENI. So unless you plan on taking your firewalls behind a load balancer there is no need to swap the mgmt interface. Hope this helps.

Re: AWS HA Setup

Eth 1 in AWS is the the Palo Alto 1/1 interface used for HA2 (Data Link)  and Eth 0 in AWS is the primary management interface and could be used for Control Link (HA1) configuration.  The rest of the interfaces can be used to route data place traffic and are the elastic network interfaces that will be swapped via IAM role in case of failover.
