Licensing for VCX30 through VCX110 models
Feature-tier licensing is available for models VCX30 through VCX110. A flexible licensing model is available for cloud models. For details about all appliance models, go to the family product specification sheet for details.
The first time you purchase a license you receive a customer key, which is used across all subsequent purchases. Licenses are tied to your customer key and are provided for model performance tier, WAN acceleration, and optional add-on features. Some features may require a challenge-response to activate the license.
In addition, a support identification code is provided for included or purchased support services.
Virtual appliances with subscription licenses must run in connected mode, which requires daily connectivity to the Cloud Portal. Virtual appliances with evaluation licenses or perpetual licenses can run in disconnected mode and do not require a connection to the internet. When a virtual appliance with a subscription license cannot connect to the Cloud Portal, an email alert is sent daily for two weeks, or until connectivity is restored, to the address that is configured on the appliance to receive event notifications. If connectivity is not restored after two weeks, the license expires and the functionality associated with it stops.
One-year, three-year, and five-year subscription licenses are available. When an appliance is licensed for a capacity that exceeds the capacity of the underlying virtual machine’s hardware configuration, it will operate at the maximum capacity allowed by the underlying virtual machine’s hardware configuration.
To use automatic licensing, the appliance must be able to connect to the internet.
Legacy models cannot use new-paradigm licenses.
To activate a license that requires a challenge-response, click Generate under Generate Challenge in the License Validation section. Copy the challenge string.

Copy the response string. Return to the appliance interface and paste the response string into the text field in the License Validation section.
Click Submit. Your license is now activated.
The challenge-response process must be completed within one hour. If the process is not completed within one hour, the challenge string and response string are invalidated. You must generate a new challenge to start again.
