    Posted Dec 03, 2013 02:19 AM

    Hi Folks,

     

    here is brief information i get about centralized license from ArubaOS 6.3.1 release Notes

     

    Centralized Licensing
    Centralized licensing simplifies licensing management by distributing AP, PEFNG, RF Protect, xSec and ACR licenses installed on one controller to other controllers on the network. One controller to act as a centralized license database for all other controllers connected to it, allowing all controllers to share a pool of unused licenses. The primary and backup licensing server can share single set of licenses, eliminating the need for a redundant license set on the backup server. Local licensing client controllers maintain information sent from the licensing server even if licensing client controller and licensing server controller can no longer communicate. You can use the centralized licensing feature in a master-local topology with a redundant backup master, or in a multi-master network where all the masters can communicate with each other (for example, if they are all connected to a single AirWave server). In the master-local topology, the master controller acts as the primary licensing server,
    and the redundant backup master acts as the backup licensing server. In a multi-master network, one controller must be designated as a primary server and a second controller configured as a backup licensing server.

     

     

    with this configuration, can i use centralized License

    my point of view is, why waste money buying license for standby controller. while other vendor doesnt charge standby controller license.

     

    thanks

    There is no separate "standby controller license" in centralized licensing.  Designating a standby controller is to determine what controller will take over as the cetralized licensing master if the master goes down.  It is the same licenses.  Even if you do not have a standby or backup licensing server, you have 30 days to get the original server back online.

    This mean we dont need to buy double amount of AP license for active standby controller  redudancy. need to double confirm this because no written article or docs state this cleary.

    Yes, that is what it means.  Please see right here in the Use Guide http://www.arubanetworks.com/techdocs/ArubaOS_63_Web_Help/Web_Help_Index.htm#ArubaFrameStyles/New_Licenses/Multi__Network.htm

     

    "Centralized licensing allows the primary and backup licensing server controllers share a single set of licenses. If you do not enable this feature, the master and backup master controller each require separate, identical license sets."
