Elevate Flexible Licensing - What happens if the AP loses Internet Connection?

The ePMP Elevate Flexible Licensing feature introduced in beta for Release 3.5 allows operators to use a the Cambium Networks Cloud Licensing Server to store and automatically use ePMP Elevate entitlements dynamically based on Elevate subscriber registration needs.  

With Flexible Licensing, the license keys are stored in a license server (Cambium Networks cloud-based) and can be shared among all Access Points in your network.  Each Access Point uses one license for each Elevate subscriber requesting registration.  When a subscriber disconnects, a license is returned to the pool and can be used by any other Access Point.

The following scenarios give examples of system operation if the AP loses Internet Connection:

  1. AP loses Internet connection while ePMP Elevate subscribers are registered:  In this case, the AP retains Elevate subscriber regsitration for one hour (including three licensing server poll requests every 20 minutes).  After one hour with no connection to the license server, the Elevate subscriber connection is dropped by the AP.  Upon restoration of the AP's Internet connection, the AP statistic Refresh Requests Failed resets to 0 and registrations are  re-initiated.
  2. AP loses Internet connection while ePMP elevate subscriber is attempting registration:  In this case, the AP attempts to connect with the license server for twenty minutes to enable Elevate subscriber registration (including four licensing server update requests every 5 minutes).  After twenty minutes with no connection to the license server, the Elevate subscriber registration request is denied by the AP.  Upon restoration of the AP's Internet connection, the AP statistic Update Requests Failed resets to 0. and registration requests are re-initiated.

The AP always retains the Cloud Licensing ID independed of the status of the AP Internet connection.
