The value of true indicates that any defined local MAC addresses and NetBIOS names will be advertised to a partner node via initial and (if supported) run-time capabilities exchange messages. The DLSw node should send the appropriate exclusivity control vector to accompany each list it sends, or to represent that the node is explicitly configured to have a null list.

The value of false indicates that the DLSw node should not send a MAC address list or NetBIOS name list, and should also not send their corresponding exclusivity control vectors.
