    Hi All,

     

    Can I configure a Master controller and 2 Backup Master controllers?

     

    The Idea is:

     

    - if the Master fail, the 1st Backup Master become Master.

    - If the Master fail and the 1st Backup Master fail, the 2sd Backup Master become Master.

     

    I read something about Cluster of Master Controllers, but I`m not sure if it will works that way. 

     

    Thanks,

     

    Ed

    You won't be able to achieve this using the master-redundancy method.

     

    But you accomplish this using the HA setup but HA is only supported on AOS 6.3 and up

    Thank you Seth and Victor.

    Controller 1 : 172.16.0.1

    Controller 2: 172.16.0.2

    Keep in my mind that .3 won't be able to see the local db sync since this only happen between controllers in the master-redundancy setup

    Are you trying to achieve AP redundancy?  I would recommend AP fast failover for that.

     

    For Master redundancy, you are limited to 2 controllers.
