 Specifies the allowed logical link connections for the node. There are
 four options:

     INCOMING    Allows logical link connections from the remote node.

     OUTGOING    Allows the local node to initiate connections to the
                 remote node, but does not allow connections from the
                 remote node.

     BOTH        Allows incoming and outgoing logical link connections.
                 This is the default.

     NONE        Does not allow incoming or outgoing logical link
                 connections to this node.
