License Server Management
Litmus uses an embedded license server to provide site-based licenses to edge devices.
After receiving a site license key from the Customer Portal, a respective site license can then be generated and added to the embedded license server. The site license will then be automatically used when activating an edge device with Litmus Edge Manager. See Activate an Edge Device for more information.
The License Server Management pane includes the following sections.
- Core License List: Shows the activated site licenses and their statuses for edge devices.
- Feature License List: Shows a list of features enabled with the activated site license.
- Offline Activation: Enables you to activate a site license key with the license portal and add the respective site license.
- License Clients tab: For Litmus Edge Manager version 2.12.0 and later. It allows you to manage the list of Litmus Edge instances that are clients to the license server. You can also add license clients directly and connect it through a proxy.
To access the license server management UI:
- Log in to the Litmus Edge Manager (LEM) Admin Console at the following URL: https://[LEM IP address]:8446.
- From the Navigation panel, select License Server Management. The License Server Management pane appears.
Note: For Litmus Edge Manager version 2.12.0 and later, the user interface is split into two tabs: License Server and License Clients.
You can view and manage the following sections in the License Server tab.
The Core License list includes the following information.
- Status: The status for each site-license feature.

Note: This version of Offline Activation is available for Litmus Edge Manager version 2.8.0 and later.
You can add a Core or an Add-on license for edge devices from the Offline Activation section in the License Server Management pane. Once the licenses are added, edge devices that have been or will be activated with a Site license will receive the Core and all the Add-on Site licenses.
While multiple Add-on licenses can be added as needed, only one Core license can exist.
Make sure you have a site-license key, which you can request from the Customer Portal.
