In this document Cisco TAC engineer "Michael Combs" has explained about How to activate AP count licenses and deactivate the evaluation license on 3850 / 5760 WLC
5700 Series Wireless LAN Controller (AIR-CT5760)
Cause / Problem Description
User recently purchased a 5760, and needs help with installing and/or activating the AP licenses.
Unlike the previous unified wireless LAN controllers, the 5760 and other converged access wireless infrastructure now use a right-to-use licensing structure. Further details and clarification of such can be found at the below URL for reference:
Q. What is right-to-use (RTU) licensing?
A. An RTU license scheme is an honor-based model for licensing. Licenses that follow this model are not tied to a unique device identifier (UDI), product ID, or serial number. For the purpose of this Q&A, the relevant licenses are access point count licenses. Access point count licenses are required on a Cisco wireless controller for access point connection and control.
You can find additional information regarding these commands in the below linked section of the latest command reference guide for 3.3SE:
Q. How is RTU licensing enabled?
A. Access point count licenses can be enabled through the command-line interface (CLI) with acceptance of an RTU end-user license agreement (EULA).
The ordering process is the same as before. Customers place an order for a controller with an embedded access point count license or a separate access point count adder license. For the access point count adder license, they will receive an e-license or paper license after payment. There is no license PAK or SWIFT, avoiding the need to access the Cisco.com portal or additional external license tools.
Q. What are the benefits with RTU licensing?
A. An RTU license scheme simplifies enabling access point adder licenses in the field by eliminating the need for an additional step or additional tools and access to Cisco.com for PAKs during installation of adder licenses or transfer of licenses from one controller to another during the RMA process.
Q. Which wireless controller products will have RTU licensing and when?
A. This document is applicable to the RTU access point count licensing on the Cisco Catalyst 3850 and Cisco 5760 WLC. The Cisco 5760 WLC and the Cisco Catalyst 3850 will support RTU-based access point count licensing.
Other wireless controller platforms such as the Cisco 5508 Wireless Controller, Cisco Wireless Services Module 2 (WiSM2), and Cisco 2500 Series Wireless Controller will continue to use the node-locked licensing model, in which the access point count licenses are tied to the hardware.

To configure right-to-use access point adder licenses on the controller, use the license right-to-use command in privileged EXEC mode.
