The MIB module for managing licenses on the system. The licensing mechanism provides flexibility to enforce licensing for various features in the system. The following description introduces different concepts and terminologies necessary to understand the MIB definition and to perform license management. Product Instance: An instance of a Cisco software image that runs on a hardware platform and requires some licensing capability. Software ID tag: A string generated by the Cisco Connected Software IT team to uniquely identify a Cisco software product. Smart Account: A Smart Licensing account that is created for Cisco customers or partners to manage their Smart Licensing product instances and licenses. The account is created on the Cisco Smart Software Manager portal. An enterprise account can have several virtual accounts (a.k.a. pools) of licenses. Cisco Smart Software Manager (CSSM): The Smart Licensing back-end system, hosted on Cisco IT infrastructure, is responsible for managing all Smart Licensing services and transactions. It provides a set of APIs that the Smart Agent can communicate with and an external-facing UI for Cisco customers and partners to log into and manage their Smart Licensing account. Registration Token: A token that is generated from the Cisco Smart Software Manager. The token is used to register a product instance with the Cisco Smart Software Manager. Smart Agent: A Smart Licensing software client that runs on a product instance and communicates with the Cisco Smart Software Manager. Entitlement Tag: A unique string that identifies a feature that can be enabled on a product instance. The tags are used by both the Smart Agent and the Cisco Smart Software Manager to track entitlement requests. Transport Mode: The Smart Agent uses the Smart Call Home (SCH) service as a transport medium to communicate with the Smart Licensing back-end. Crypto (LCS) Service: In addition to HTTPS exchanged messages are further signed and verified on both sides to ensure the authenticity of all communication. The Smart Software Licensing system uses a crypto service and underlying crypto library (either CiscoSSL or PKI). The Smart Software Licensing back-end leverages the Licensing Crypto Service (LCS) service. UDI: Unique Device Identifier that uniquely identifies a device. Primarily it consists of a product ID, version ID and serial number of the Customers device. Grace Period: A product enters into a grace period when the authorization period expires. This is the result of multiple authorization attempt failures which occurring 90 days after the last successful authorization. The grace period continues until the grace period expires - 90 days after the grace period starts. Counted License: Limits the number of similar entities that can consume a license. For example, a counted license when used by a feature can limit the number of IP phones that can connect or the number of tunnels that can be created. Evaluation License: An Evaluation License grants the right to a customer to enable functionality of a product instance before registering it and without an explicit portal based license for a limited amount of time. This amount of time ranges on average between 60 to 90 days. Evaluation licenses are available for most functionality, but may be limited for a variety of reasons such as legal, royalty, regulatory, or other causes. This MIB module also defines various notifications that will be triggered to asynchronously notify the management application of any critical events.
