Re: Local Controller Discovery

I am looking at the "Aruba Implementing WLAN" guide and on page 4-9 it lists the controller discovery order as:


  1. Static (set master-controller and set ip-address)
  2. DHCP Option 43
  3. ADP
  4. DNS


 Are you able to confirm the controller discovery order?   I would prefer to use ADP but may have to use DHCP Option 43 if it occurs before ADP.




Kind Regards,

Re: Local Controller Discovery

ADP only means the AP finds the controller on the same subnet.   If your APs at that new site will be on the same subnet as the new controller you are set.  


The only issue with that is if the controller is rebooting and the APs are rebooting at the same time, they will not find the local controller because it cannot answer, and instead  they will find the master controller via DNS.  I would go with the DHCP option so that those APs are always pointing at the correct controller.
