  VnfExtCpConfig:
    description: >
      This type represents an externally provided link port or network address
      information per instance of an external connection point. In case a link
      port is provided, the VNFM shall use that link port when connecting the
      external CP to the external VL. In a link port is not provided, the VNFM
      shall create a link port on the external VL, and use that link port to
      connect the external CP to the external VL.
      NOTE 1:	The following conditions apply to the attributes "linkPortId" and "cpProtocolData":
        -	At least one of the "linkPortId" and "cpProtocolData" attributes shall be present for
        an external CP instance representing a subport that is to be created, or an external CP instance
        that is to be created by creating the corresponding VNFC or VNF instance during the current or
        a subsequent LCM operation, or for an existing external CP instance that is to be re-configured
        or added to a particular external virtual link.
        -	If the "cpProtocolData" attribute is absent, the "linkPortId" attribute shall be provided
       referencing a pre-created link port with pre-configured address information.
        -	If both "cpProtocolData" and "linkportId" are provided, the API consumer shall ensure that
        the cpProtocolData can be used with the pre-created link port referenced by "linkPortId".
      NOTE 2:	In case the NFVO manages its own identifier space, the NFVO may remap this identifier
      when communicating with the VNFM. If the NFVO knows that there can be an identifier collision
      when communicating with the VNFM by using the identifier from the OSS/BSS, the NFVO shall remap it.
