      2) Disconnect and delete external CPs that are connected to a particular external VL and that represent subports
         in a trunk, i.e. CP instances that are created from external CPDs that have trunk mode configured according to
         clause 7.1.6.3 in ETSI GS NFV-IFA 011. If the parent port is exposed as an "extCp", the VNFM shall ensure that
         the parent port is not deleted. If the parent port is exposed as an "extCp" and there are other subports connected,
         the VNFM shall ensure that the parent port is not disconnected, unless it is reconnected to a different external
         VL in the same operation.
      3) Change the connectivity parameters of the existing external CPs, including changing addresses.

      NOTE:	Depending on the capabilities of the underlying VIM resources, certain changes (e.g. modifying the IP address
            assignment) might not be supported without deleting the resource and creating another one with the modified
            configuration.

      4) Create new CPs that represent supports in a trunk, i.e. CP instances that are created from external CPDs that
         have trunk mode configured according to clause 7.1.6.3 in ETSI GS NFV-IFA 011, and connect them to a particular
         external VL. Creation of the parent port with this operation is not supported. This type shall comply with the
         provisions defined in Table 6.5.3.33-1.
