Managing the license is a primary Control Plane task required to activate software modules and features on a BIG-IP device.

License Management Utility: All actions related to the device license, including initial activation, renewal, and adding add-on keys, are performed under the System > License section of the Configuration Utility.

Procedural Requirements: Licensing often requires the generation of a "dossier," which is a unique encrypted string used by the F5 License Server to generate the final license file.

Impact on Services: Updating or re-activating a license generally requires a restart of system services (such as the tmm daemon), which will temporarily disrupt traffic processing unless performed on a standby unit in a high availability pair.

Add-on Licenses: If an administrator needs to increase the capacity of a specific module (like increasing the SSL TPS limit or adding a new module like ASM), the new registration keys are entered through this same interface using the "Re-activate" button.
