Second backup-LMS in ArubaOS 8?

Hi gurus,

 

I have three sites geographically separated and L3 connected, each one with one controller. I know I can have site1's APs pointing to site1's controller, and if this controller fails, the APs can fail over to the site2's controller, as indicated with the backup-LMS in the AP system profile.

 

Now, is possible to have site1's APs pointing to site1's controller as the primary controller, site2's controller as secondary controller is site1's controller fails, and site3's as tertiary controller if site1 and site2's controllers fail? Many thanks in advance.

 

Regards,

Julián

Unfortunately, there is no way to do this.

Hi Colin,

 

I forgot to say, but I will also have a MM for managing the three controllers. I guess it is not possible either with a MM. Can you confirm?

Controllers do not fail often (the only moving part is typically a fan in the power supply).  If you need high availability at a site because you need wireless 24/7 put a second controller there.   Failing over to a second site is very disruptive, because all devices will have to request a different ip address (if the device even detects the failover).  This is not to mention the slowness of the WAN between sites that would make wireless painful.

Sure, I agree. But my customer has limited budget and a second controller at the site will be in a second phase. But in the meantime and in the case of a controller failure is better to have a regular wireless service for a while than not wireless at all.

Well, the customer will be satisfied with Backup LMS, because controllers do not fail often.
