Re: Aruba MM and MD with RAP deployment

NAT and Clusters for RAPs are still not supported as of 8.3.x.x.

 

The issue has to do with how the nodelist for the cluster gets sent to the AP/RAP for controller selection in a cluster environment. If the public IPs do not live on the controllers themselves, then the initial controller that pushes the nodelist to the RAP is unaware of the NAT environment. Consequently, the RAP gets pushed a set of private IPs that it is unable to connect to.

 

If 1:1 NAT is required in order to reach a controller for RAP connectivity, then today that controller can not be a cluster member.

Re: Aruba MM and MD with RAP deployment

Thanks. It's a lot clearer now.

The question is, perhaps can we use FQDNs for nodelist?

Re: Aruba MM and MD with RAP deployment

So to summarize. 

There is no RAP redundancy with cluster connected MD's.  

Redundancy can be achieved using non-clustered MD's where you push the public IP (or NATed IP) as LMS-IP/ BKUP-LMS-IP in the AP System profile to the RAP.

Obviously not ideal, is cluster redundancy for RAPs a roadmap item?

For roadmap details, contact your Aruba sales team.

 

Your redundancy summary is pretty complete. Two further additions... VRRP can be run on the RAP controllers for increased availability. DNS can also be used to return multiple IPs for the RAP controllers to a RAP that’s booting.

The nodelist uses IP rather than FQDN.
