Creates an instance of an alias port entity.  An alias port entity
    provides a means to define an alternate network address for this
    node, which is shared by other nodes in the same OpenVMS cluster.

    create [node node-id] alias port port-name [node id LAN-address]

    The first node in the OpenVMS cluster to create an alias port for
    a particular alias address causes that alias to be created.
    Subsequent nodes that create an alias port for the same alias
    establish connections (ports) to that alias.  The alias becomes
    active when the first node enables its alias port for that alias.

    The Node Id argument is optional.  It is a LAN address used to
    build the Alias node NSAP.

    Example:

    create alias port dec:.lkg.bulean node id aa-00-04-00-45-13
