To activate the license on your VM-Series firewall, you must have deployed the VM-Series firewall and completed initial configuration. To deploy the firewall, see VM-Series Deployments.
Use the instructions in this section for all the BYOL models including AWS and Azure; for usage-based licensing in AWS and Azure, you do not need to activate the license. For the usage-based licenses, you must Register the Usage-Based Model of the VM-Series Firewall in AWS and Azure (no auth code) in order to activate your premium support entitlement.
For usage-based models of the VM-Series firewall in the AWS Marketplace, the longer AWS instance IDs are not supported; use the shorter 8‐character instance ID format. To disable longer instance IDs in each AWS region where you deploy the VM-Series firewall: Select your AWS region on the EC2 dashboard, select Resource ID length management and clear the check box for Instance ID. Because the longer instance ID is currently optional, you can disable it without limiting functionality in AWS or on the VM-Series firewall. The VM-Series firewall will be be updated to support the longer instance IDs, and your VM-Series firewalls with shorter instance IDs will continue to be operational after the update.
Until you activate the license on the VM-Series firewall, the firewall does not have a serial number, the MAC address of the dataplane interfaces are not unique, and only a minimal number of sessions are supported. Because the MAC addresses are not unique until the firewall is licensed, to prevent issues caused by overlapping MAC addresses, make sure that you do not have multiple, unlicensed VM-Series firewalls.
When you activate the license, the licensing server uses the UUID and the CPU ID of the virtual machine to generate a unique serial number for the VM-Series firewall. The capacity auth code in conjunction with the serial number is used to validate your entitlement.
After you license a VM-Series firewall, if you need to delete and redeploy the VM-Series firewall, make sure to Deactivate the License(s) on the firewall. Deactivating the license allows you to transfer the active licenses to a new instance of the VM-Series firewall without help from technical support.
