Description
A VnfExtCpDesc is a type of Cpd and describes an external interface, a.k.a external CP, exposed by this VNF enabling connection with a VL. A VnfExtCpDesc inherits from the VNFCCPDesc Class). All attributes of the VNFCCPDesc are also attributes of the VnfExtCpDesc .
When the VnfExtCpDesc is mapped to a VNFCCPDesc, the values for the attributes type, subType and description shall be identical for both elements.
