This is an enumerated CucsPolicyPolicyOwner value indicating who controls the policy governing the UCS-side definition (VLAN/PVLAN and allowed vNIC type) used to generate a FabricNetwork on the VMM. It tells an admin whether that network definition is locally managed within this UCS domain or is instead controlled centrally (e.g. by UCS Central), which changes where a config change actually needs to be made. A value of 'policy' (local) versus 'central' would tell an admin whether editing that network definition's configuration here in UCS Manager will actually take effect or get overwritten from a central policy source.
