This is an enumerated CucsPolicyPolicyOwner value indicating who controls the policy governing a VM network (distributed-switch port group) that UCS pushed into the external VMM for VM-FEX use by VMs. It tells an admin whether that pushed VM network 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 pushed VM network's configuration here in UCS Manager will actually take effect or get overwritten from a central policy source.
