    DESCRIPTION
            "Defines the objects necessary to support the management of
            Bridge objects.

            Add rbnBridgeCircuitStateEvent notification along with 
            the associated objects. Defined rbnBridgeNotifyObjectGroup and 
            rbnBridgeNotifyGroup for compliance."

    REVISION      "200808270000Z" -- August 27, 2008
    DESCRIPTION
            "Updated dot1dStpPortState in place of current port state,
            and changed rbnBridgePortPrevState to rbnBridgePortPreviousState
            for trap, and updated groups accordingly."

    REVISION      "200802250000Z" -- Feb 25, 2008
    DESCRIPTION
            "Add rbnBridgeCompliance2, rbnBridgeStateNotifyObjectGroup,
