This page gives a detailed definition for features on license servers and license server groups  

Feature and its parts

The following diagram shows an example of features with the same name but with different versions and license types.

Features Example

A feature on a license server refers to a feature with a particular name, version and type on a particular license server. This means that features with the same name and different versions can be placed on different license servers. 

The example below shows features that are on two License Servers, one in the USA and one in Poland.

Note: This example is based on the license servers having the same vendor; otherwise, there could be conflicts between name, version, and type.

How features for license server groups are reported

The actual name and version, not the user-defined name and version fields, are shown for license server groups. Duplicated names/versions are ignored; that is, only one name/version of any duplicate names/versions will be displayed.

Example  

Let's assume we have three license servers: server PL in Poland, server US in the United States, and server DK in Denmark. Each server contains the feature Windows XP Floating (WXPF) and belongs to a license server group called XF. The XF license server group has the aggregated data gathered for each WXPF feature on PL, US, and DK. 

The total available licenses for WXPF per license server are:

Therefore, the total available licenses for WXPF for the license group XF = 30.
