During auto-provisioning of the NetScaler VPX instance using OpenStack orchestration, the NetScaler Management and Analytics System (MAS) uses OpenStack Compute to launch a NetScaler VPX instance. The newly provisioned NetScaler VPX instance contacts the Citrix licensing portal during the set up, and uses the License Activation Code (LAC) to automatically download and install the license files.
Technical support staff use trial licenses when they install NetScaler MAS and NetScaler VPX devices in field. A trial or evaluation license for NetScaler VPX is valid for 90 days. If there is a need to evaluate more than one NetScaler or extend the testing after 90 days, a new evaluation license needs to be requested. Instead of automatic installation of trial license files, NetScaler MAS provides you an alternate solution. You can manually download the license files and install them on NetScaler VPX to complete the installation of the instance.
If the NetScaler VPX is unable to connect to the internet, configure the NetScaler MAS to act as a proxy server for the Citrix Licensing Portal and install the license files.
NetScaler VPX instances that have a trial license can communicate with NetScaler MAS on HTTP only. To configure HTTP communication in NetScaler MAS, navigate to System > System Administration, and click Change System Settings. Select http from the drop-down list to set the communication method, and click OK.
