Manage Licenses 
Licenses are required to access and utilize specific features and functionalities of A10 Control and Thunder devices that need to be registered with A10 Control. By default, licenses in A10 Control are created and managed with GLM.
| NOTE: |
|
On purchasing a device, the organization's administrator receives the License Token email that includes:
- Ordered information: The license details including license expiry date.
- License Entitlement Token: The license token that is used to activate the device.
- Registration Link: Click the Registration Link, if admin does not have an A10 GLM account. Follow the instructions provided in the email to Confirm your account.
- Appliance Activation Link: Click the Appliance Activation Link, if admin has the A10 GLM account. Log into GLM https://glm.a10networks.com and activate the appliance. For more information, see GLM User Guide.
The licenses can be acquired using the following A10 License Managers:
- Global License Manager (GLM): For A10 Control deployment, you can acquire a license from GLM https://glm.a10networks.com. For more information, see GLM User Guide.
-
Local License Manager (LLM): It is designed for A10 Control deployments that operate in isolated or air-gapped networks. It provides a self-contained licensing solution that operates without an internet connection. Licenses are sourced from the Global License Manager (GLM), manually exported, and then imported into the LLM.
In A10 Control the following types of licenses are managed through LLM mode:
- Management license: A10 Control and A10 Control ADO licenses are supported. These licenses are used to connect and manage devices. When you install A10 Control, the Trial license is available by default.
-
Flexpool device license: Capacity Flexpool and Instance Flexpool license through A10 Control are supported. The flexible pool of licenses can be used to run multiple devices. This license allows you to modify the device license configuration from A10 Control, which you can otherwise achieve through the device CLI.
When a Capacity Flexpool license is assigned to a Thunder instance and the device is later deregistered, the license is automatically removed from the device. The released capacity is then returned to the central license pool, making it available for reuse.
-
External License Manager: A10 Control supports the External License Manager capability to centrally manage and allocate FlexPool licenses in large-scale environments where multiple A10 Control instances are deployed. This centralized approach simplifies license administration and ensures efficient utilization of shared licensing resources across distributed deployments.
With External License Manager, a designated A10 Control instance acts as the central license authority, allowing it to issue and manage Capacity FlexPool licenses not only for its own connected devices but also for devices connected to other A10 Control instances. This model is especially beneficial in scenarios such as:
- Multi-instance A10 Control deployments across regions or tenants.
- Dynamic environments requiring license allocation or revocation based on device onboarding and lifecycle events.
-
Key Benefits:
-
Centralized license visibility and tracking across all connected environments.
-
Simplified provisioning and revocation of licenses from a single control point.
-
Improved license efficiency, reducing the risk of over-provisioning or under-utilization.
-
In the Controller administrator scope, you can choose the license manager and in the Organization administrator scope, you can manage licenses. Log in with super-admin credentials to choose the license manager. All organization administrator accounts use the same license manager after it is selected by the super-admin.
The licenses are managed by following scopes:
