Functionality associated with a license stops when a license expires. For example, when the FIREEYE_APPLIANCE license expires, CLI commands (except those that install licenses) are disabled or their execution fails. For example, the report generate command will not create a report. In addition, the Intelligent Virtual Execution - Server appliance will block access to all Intelligent Virtual Execution - Server pages except for the Appliance License Settings page. (Intelligent Virtual Execution - Server pages are accessed only through the managing Central Management System Web UI because the Intelligent Virtual Execution - Server appliance has no Web UI.)
