License Server Management

12min

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.
