The entity hierarchy of the Token Ring module is:

    Node___Token_Ring____Port
                       |
                       |_Station____Source_Route
                                  |
                                  |_FA_Map

    The TOKEN RING entity is the top-level entity in the hierarchy of
    entities belonging to the Token Ring module.

    A TOKEN RING PORT entity represents an access point to the service
    offered by the Token Ring module.  A client transmits and
    receives data through a port.  Ports are created and deleted by
    client use of open and close service interface procedures.
    The port-name refers to the port managed by this command.

    A TOKEN RING STATION entity manages a Token Ring controller. Each
    station corresponds to a particular instance of Logical
    Link Control (LLC), Medium Access Control (MAC), and physical
    attachment. The Token Ring data link can be monitored and controlled
    through DNA network management. The station-name refers to the
    station managed by this command.

    A TOKEN RING STATION SOURCE ROUTE entity describes an entry in the
    Source Routing database. In Transparent Source Routing, the Source
    Route entities are typically created and enabled by the parent
    Station entity. The sourceroute-id refers to the source route
    entity managed by this command.

    The TOKEN RING STATION FA MAP (Functional Address Mapping) entities
    describe the default Functional Address-Global Address mapping to be
    applied to ports that are created with the same protocol identifiers.
    The famap-id refers to the FA map entity managed by this command.
