I'm trying to provision a new External Network into vCD, which requires a field called "Port group IP" or portGroupMoRef, to be more specific. However, the only way I can find that identifier is by going out to the Administer section of VCO, then re-loading the vCenter plugin and selecting that particular port group.
Even PowerCLI doesn't provide the identifier in the proper format, as it's preceded by a long "DistributedVirtualPortgroup-" field.
