          security or acceleration features, or to address particular network topologies. The present document

          Current values of the configurable properties of the VNF instance.
          Configurable properties referred in this attribute are declared in
          the VNFD.
          ETSI GS NFV-SOL 001 specifies the structure and format of the VNFD
          based on TOSCA specifications.
          VNF configurable properties are sometimes also referred to as
          configuration parameters applicable to a VNF. Some of these are set
          prior to instantiation and cannot be modified if the VNF is
          instantiated, some are set prior to instantiation (are part of
          initial configuration) and can be modified later, and others can be
          set only after instantiation. The applicability of certain
          configuration may depend on the VNF and the required operation of
          the VNF at a certain point in time.
          These configurable properties include the following standard
          attributes, which are declared in the VNFD if auto-scaling and/or
          auto-healing are supported by the VNF:
          * isAutoscaleEnabled: If present, the VNF supports auto-scaling. If
            set to true, auto-scaling is currently enabled. If set to false,
            auto-scaling is currently disabled.
          * isAutohealEnabled: If present, the VNF supports auto-healing. If
            set to true, auto-healing is currently enabled. If set to false,
            auto-healing is currently disabled.
          These configurable properties can be initialized with default values
          from the VNFD.
          Configurable properties can be modified with values passed in the request
          structures of certain LCM operations, such as the InstantiateVnfRequest
          structure.
          Further, these configurable properties can be created, modified or
          deleted with the PATCH method.

          NOTE: Upon creation of the VnfInstance structure, the VNFM shall create and initialize all child attributes
          of "vnfConfigurableProperties", "metadata" and "extensions" that were declared in the VNFD with a defined
          initial value. The defined initial values can be declared in the VNFD, and/or, in case of "metadata",
          obtained from the "CreateVnfRequest" structure. Child attributes of "vnfConfigurableProperties", "metadata"
          and "extensions" that have no defineddeclared initial value shall not be created, in order to be consistent
          with the semantics of the JSON Merge Patch method (see IETF RFC 7396) that interprets null values as deletion
          request.

          Upon creation of the VnfInstance structure, the VNFM shall create and initialize all child attributes
          of "vnfConfigurableProperties", "metadata" and "extensions" that were declared in the VNFD with
          a defined initial value. Child attributes of "vnfConfigurableProperties", "metadata" and "extensions"
          that have no declared initial value shall not be created, in order to be consistent with the semantics
          of the JSON Merge Patch method (see IETF RFC 7396) that interprets null values as deletion request.

      extensions:
        description: >
          Additional VNF-specific attributes that affect the lifecycle management of this VNF instance.
          These attributes represent values that are stored persistently in the VnfInstance structure
          for consumption by the VNFM or the lifecycle management scripts during the execution of
          VNF lifecycle management operations.
          All extensions that are allowed for the VNF are declared in the VNFD. The declaration of an extension
          in the VNFD contains information on whether its presence is optional or required, and optionally
          can specify an initial value. See note 2 and note 4. The VNFM shall reject requests to write extension
          attributes that are not declared in the VNFD with a "422 Unprocessable entity" error response as defined
          in clause 6.4 of ETSI GS NFV-SOL 013.
          Modifying the values of these attributes has no direct effect on the VNF instance; however, the modified
          attribute values can be considered during subsequent VNF lifecycle management operations, which means that
          the modified values can indirectly affect the configuration of the VNF instance.
          These attributes can be initialized with default values from the VNFD.
          These attributes can be modified with values passed in the request structures of certain LCM operations,
          such as the InstantiateVnfRequest structure.
          Further, these attributes can be created, modified or deleted with the PATCH method.

          NOTE: Upon creation of the VnfInstance structure, the VNFM shall create and initialize all child attributes
          of "vnfConfigurableProperties", "metadata" and "extensions" that were declared in the VNFD with a defined
          initial value. The defined initial values can be declared in the VNFD, and/or, in case of "metadata",
          obtained from the "CreateVnfRequest" structure. Child attributes of "vnfConfigurableProperties", "metadata"
          and "extensions" that have no defineddeclared initial value shall not be created, in order to be consistent
          with the semantics of the JSON Merge Patch method (see IETF RFC 7396) that interprets null values as deletion
          request.

      VNF LCM operation occurrence that changes the VNF lifecycle, includingwhich represents an
      occurrence of one the following LCM operations:
      * Instantiation of the VNF
      * Scaling of the VNF instance (including auto-scaling)
      * Healing of the VNF instance (including auto-healing)
      * Change of the state of the VNF instance (i.e. Operate VNF)
      * Change of the deployment flavour of the VNF instance
      * Change of the external connectivity of the VNF instance
      * Termination of the VNF instance
      * Modification of VNF instance information and/or VNF configurable
        properties through the "PATCH" method on the "Individual VNF instance"
        resource
      * Creation of a VNF snapshot
      * Reversion of the VNF instance to a VNF snapshot.
      Clause 5.6.2 defines the states and state transition of a VNF LCM operation occurrence,
      and also specifies details of the notifications to be emitted at each state transition.
      If this is the initial notification about the start of a VNF LCM operation occurrence,
      it is assumed that the notification is sent by the VNFM before any action (including sending the grant request)
      is taken as part of the LCM operation. Due to possible race conditions, the "start" notification,
      the grant request and the LCM operation acknowledgment (i.e. the "202 Accepted" response)
      can arrive in any order at the NFVO, and the NFVO shall be able to handle such a situation.
      If this is a notification about a final or intermediate result state of a VNF LCM operation occurrence,
      the notification shall be sent after all related actions of the LCM operation that led
      to this state have been executed.
      The new state shall be set in the "Individual VNF LCM operation occurrence" resource before
      the notification about the state change is sent.
      See clause 5.6.2.2 for further provisions regarding sending this notification, including
      in cases of handling LCM operation errors.
