license in the available pool, it communicates this change to the licensing server master switch, which updates
the table before synchronizing it with the other clients.
Client switches do not share information about built-in licenses to the licensing server. A switch using the
centralized licensing feature will use its built-in licenses before it consumes available licenses from the license
pool. As a result, when a client switch sends the licensing server information about the licenses that a client is
using, it only reports licenses taken from the licensing pool, and disregards any built-in licenses used. For
example, if a switch has a built-in 16-AP license and twenty connected APs, it will disregard the built-in licenses
being used and report to the licensing server that it is using only four AP licenses from the license pool.
When centralized licensing is first enabled on the licensing server, its licensing table only contains information
about the licenses installed on that server. When the clients contact the server, the licensing server adds the
client licenses to the licensing table, then sends the clients information about the total available licenses for
each license type. In the following example, the licenses installed on two client switches are imported into the
license table on the license server. The licensing server then shares the total number of available licenses with
other switches on the network.
Figure 10 Licenses Shared by Licensing Clients
When a new AP associates with a licensing client, the client sends updated licensing information to the server.
The licensing server then recalculates the available total, and sends the revised license count back to the clients.
If a client uses an AP license from the license pool, it also consumes a PEFNG and a RFProtect license from the
pool, even if that AP has not enabled any features that would require that license. A switch cannot use more
licenses than what is supported by its switch platform, regardless of how many licenses are available in the
license pool.
