Usage Guidelines
If you no longer need a permanent license, you must officially return it to the Smart Software Manager. If
you do not, the license stays in an in-use state and cannot be used elsewhere.
When you enter this command, the Firepower 4100/9300 chassis immediately becomes unlicensed and moves
to the Evaluation state.
To complete the return, go to https://software.cisco.com/#SmartLicensing-Inventory, locate your Firepower
4100/9300 chassis using its universal device identifier (UDI), and then remove the product instance.
