      * NOTE 2:	 A link port is not needed for an external CP instance that exposes a CP in the following cases:
                1) For a virtual IP CP directly exposed as an external CP:
                  1.1) No dedicated IP address is allocated as virtual IP address, as indicated in the VNFD.
                  1.2) A dedicated IP address is allocated as virtual IP address, but the NFVO indicates that no port is
                        needed (createExtLinkPort in VnfExtCpconfig set to false).
                2) For a virtual IP CP exposed as an external CP via a floating IP address:
                  2.1) No dedicated IP address is allocated as virtual IP address, as indicated in the VNFD, and the VNFC
                      CP associated to the virtual IP CP is also exposed via a floating IP address.
                3) For a VIRTUAL CP exposed as an external CP.
                4) For a VNFC CP exposed as an external CP in a secondary container cluster external network.

  SubscriptionAuthentication:
      * NOTE 1 : The clientId and clientPassword passed in a subscription shall not be the same as the clientId and
                clientPassword that are used to obtain authorization for API requests. Client credentials may differ between
                subscriptions. The value of clientPassword should be generated by a random process.
      * NOTE 2: As a less secure alternative to OAUTH2_CLIENT_CERT which uses mutual authentication based on X.509
                certificates, this mode which uses client password to authenticate may be used in the access token request
                toward the authorization server (as defined by IETF RFC 6749 [7]), only to support legacy implementations
                (version 3.4.1 or earlier version of the present document). See clause 8.1 for more details.
      * NOTE 3: The following values that were included up to version 3.4.1 of the present document have been removed:
                "BASIC" (to signal the use of the basic HTTP authentication) has been removed because it is insecure.
                "TLS_CERT" to signal an alternative non-token based authorization method using TLS certificates has been
                removed because the method is no longer supported.
      * NOTE 4: The client certificate is established by means outside the scope of the present document.
