Prior to IOS XE 17.3.2, The IOS XE product used to boot in evaluation-mode, per product software and registration, and on-going communication every 30 days with the Cisco cloud was required.
While now, with Smart Licensing using Policy, the Device has all Licenses IN USE right out of the box. Plus, the earlier concepts, Evaluation mode, Registration, and Reservation is eliminated.
As a new deployment method for Smart Licensing, Cisco has introduced Smart License Using Policy following the IOS XE Amsterdam 17.3.2 and later. This new version supports following Cisco products: Cisco Catalyst 9000 series switches, routing platforms such as the ASR1K, ISR1K, ISR4K, Cisco Catalyst 9800 Series Wireless Controllers, IOT routers and switches, ACI, NX-OS, MDS and a few Collab products (CME, SRST, CUBE).
With this method, no evaluation mode is available at product boot and registration to cisco.com is not required anymore. Instead, customers should report them in use licenses either by using an automated reporting tool, API reporting, or direct connection from a product using a trusted connection to CSSM, or they can manually upload software use records (RUM reports) directly to CSSM via the Upload Usage Data button under the Reporting and Usage Data Files tabs. Moreover, there is a CSLU - Cisco Smart Licensing Utility that comes with Smart Licensing using Policy as a Smart Licenses Manager.
