ANSI Standard X3T9.5
SMT (Station Management) manages the FDDI station. It controls internal FDDI station processes and protocol compliance and provides an interface for human intervention. Internal SMT management functions consist of three major categories: SMT Frame Services, Ring Management (RMT), and Connection Management (CMT). Interfaces from SMT to each of these station components permit monitoring and control for a variety of station functions (see Figure

SMT Frame Services generates and interprets special FDDI frames that assist in network control and monitoring.
Ring Management (RMT) monitors status information from the MAC and Configuration Management and controls several functions relating to the health of the ring.
