    Gents,

     

    Where I can get more information about Stand-alone controller?

     

    If I have a Lab.. 

    -How the APs from the MASTER controller are going to react if I join a stand-alone controller to the same network with the same subnet, gateway but diferent statis IP? 

     

    Any info will be appreciated 

     

    Regards!

    When booting AP's will try and discover a controller in a set order.

     

    1)    “master” parameter set (manualy) on the AP

    2)    dhcp option 43

    3)    ADP multicast & broadcast

    4)    DNS aruba-master

     

    So if you have not the master ip setting in each AP and have not configured DHCP option 43, you're AP's will be using ADP to find a controller.  If your both your controllers and your AP's are in the same vlan there's no telling which controller your AP's will connect too.

     

     If your AP's are in different vlans from both controllers (and no master settign or DHCP option) then they will attempt attempt to connect to the ip address they obtain through resolving aruba-master.

    Turn off ADP and setup DHCP option 43
