Some Avaya products do not share licenses from a single license file as each element instance requires a separate license file. You require a dedicated WebLM server to host the relevant license file of the associated element instance. In this licensing model, you require the same number of WebLM servers as the number of products that you install and configure. In the virtualized environment, this model requires additional virtual machines for each element instance, thus increasing the VMware licensing cost. Thus, you cannot centrally manage the licenses for a product and must log in to each WebLM server and manage licenses for each element instance.

WebLM supports centralized licensing feature so that products can have multiple license files installed for multiple instances of the product. On a single WebLM server, you can install multiple license files of a product and associate specific license files to specific element instances.

After you enable centralized licensing from the WebLM interface, you can install multiple license files for the same product. You can add multiple element instances, and associate each license file to an element instance. The WebLM server provides licenses to the element instances based on the association you define.
