description: >
Identifier of the VNFD on which the VNF instance is based.
This attribute can be modified with the PATCH method.
Modifying the value of this attribute shall not be performed
when conflicts exist between the previous and the newly referred
VNF package, i.e. when the new VNFD is not changed with respect
to the previous VNFD apart from referencing to other VNF software
images. In order to avoid misalignment of the VnfInstance with
the current VNF's on-boarded VNF package, the values of attributes
in the VnfInstance that have corresponding attributes in the VNFD
shall be kept in sync with the values in the VNFD.

vnfConfigurableProperties:
description: >
Current values of the configurable properties of the VNF instance.
Additional VNF-specific attributes that provide the current values
of the configurable properties of the VNF instance.
These attributes represent values that are stored persistently in
the VnfInstance structure and that correspond to configuration
parameters of the VNF instance.
Modifying these attributes affects the configuration of the VNF
instance either directly (if the VNF instance is in INSTANTIATED
state at the time of the modification) or as part of the subsequent
VNF instantiation operation (if the VNF instance is in NOT_INSTANTIATED
state at the time of the modification).
Configurable properties referred in these attributes shall be declared
in the VNFD.
The declaration of configurable properties in the VNFD can optionally
contain the specification of initial values.
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.

metadata:
description: >
Additional VNF-specific metadata describing the VNF instance.
Metadata that are writeable are declared in the VNFD.
Additional VNF-specific attributes that provide metadata describing the VNF instance.
These attributes represent values that are stored persistently in the VnfInstance
structure for consumption by functional blocks that invoke the VNF lifecycle management
interface. They are not consumed by the VNFM, or the lifecycle management scripts.
Modifying the values of these attributes has no effect on the VNF instance, it only
affects the information represented in the VnfInstance structure.
Metadata that VNF provider foresees shall be declared in the VNFD. The VNFM shall
accept requests to write metadata that are not are declared in the VNFD.
These attributes can be initialized with default values from VNFD and/or with values
passed in the CreateVnfRequest structure (see clause 5.5.2.3).
This attribute can be modified with the PATCH method.

extensions:
description: >
VNF specific attributes that affect the lifecycle management of this VNF instance by the VNFM,
or the lifecycle management scripts. Extensions that are writeable are declared in the VNFD.
This attribute can be modified with the PATCH method.
ETSI GS NFV-SOL 001 specifies the structure and format of the VNFD based on TOSCA specifications.
Additional VNF specific attributes that affect the lifecycle management of this
VNF instance by the VNFM, or the lifecycle management scripts.
These attributes represent values that are stored persistently in the VnfInstance
structure for consumption by the VNFM, or by the lifecycle management scripts
during the execution of VNF lifecycle management operations.
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.
All extensions that are allowed for the VNF shall be declared in the VNFD.
This attribute can be be initialized with default values from VNFD and/or
with values passed in the InstantiateVnfRequest structure (see clause 5.5.2.4).
A value initialised with default values from the VNFD can be updated with values
passed in the InstantiateVnfRequest structure.
Further, these attributes can be modified with the PATCH method.
