Converting a pair of Local VRRP controllers to run on their own

    Posted Jul 14, 2017 03:31 PM

    Current wireless setup is one master controller and 3 pairs of local controllers setup in VRRP each pair at 3 locations. One of those pairs is at a location where they want to change so they can run on their own code version and have their own configuration without having to change our master configuration. I'm assuming they would need master / local setup could they still use VRRP or would it simply be the master becomes the backup in a case the local stops working. I'm assuming if you did 2 standalones with VRRP have to license both controllers in case of failure of one.

    Your assumption is correct. You should convert the pair to masters. This requires a reboot of both.
    If you were using centralized licensing you would need to move licenses off the centralized master to the new pair . You should then convert one of the new masters to a backup master to have a master, backup-master pair so that the configuration will stay in sync between them..

    Would you put the licenses on the active and the backup master would not need license if it fails over and the backup is now in use we would have 30 days to get the primary backup much like the master local setup if you lost the master controller?

    If you have centralized licensing with master redundancy, only one controller would be the master, so only one would terminate APs...  The 30-day restriction would not come into play, because the licenses would "follow" whatever controller becomes the master.

    If we want to centeralize license's which we do then master / local could we still do VRRP between master / local in that case.

    To be clear, you would only need centralized licensing when you want an AP to be able to connect to more than one controller for redundancy, but you don't want to pay for twice the AP, PEFNG or RFProtect licenses.  If APs are only going to connect to a single controller, centralized licensing is not really of much use.  If you don't need redundancy, centralized licensing might not be of much use in your network.

     

    To answer your question, Centralized licensing can be leveraged in a master/backup, or master/backup/local cluster.

    Can we get redundancy and use centeralized licensing with 2 controllers such as master/maseter  with VRRP I guess that was my question
