Controller Redundancy

    Our Aruba System is working across 6 sites.

     

    We have three controllers M1, L1 and L2 where M1 is the master controller and L1 and L2 are local controllers. M1 is present at site-1.L1 is present at site-3 and L2 is present at site-5. AP's at site-1 and site-2 are terminated on M1. AP's at site-3 and 4 are terminated on L1. AP's at site-5 and 6 are terminated on L2.All sites belong to a different AP group. Site-2 AP group has LMS ip of M1 and backup LMS ip of L1.site-2 is connected to M1 via a WAN link.

     

    If there is no connectivity between site-2 AP's and M1 due to WAN link failure, will my site-2 AP's move to L1 ?

     

    I am posting this beacuse in one of the Aruba Trainings we got to know that AP's terminated on Master Controller cannot switch to Backup LMS ip if there is WAN Link failure or Master Controller failure.

    Do you have a WAN link from site2 to site3 where L1 is connected to the network? If so then I think the AP's will fail over to the L1 controller if they lose connection to M1.

    Yes, there is a WAN link between site-2 and site-3.

    I guess the APs will fail over to L1 in this case.
