Description: Standard FDDI SMT 7.3 MIB (RFC 1512) for managing FDDI ring parameters, stations, paths, and ports.

IPNetwork Monitor uses several OIDs from this MIB in network discovery and polling the applicable devices. Start monitoring FDDI-SMT73-MIB with a free 30-day trial of IPNetwork Monitor.

What Is FDDI-SMT73-MIB?

FDDI-SMT73-MIB, standardized in RFC 1512, is the vendor-neutral MIB for managing FDDI networks according to the Station Management (SMT) version 7.3 specification, covering ring, station, path, and port-level configuration and status. It exposes objects describing the FDDI ring's overall state, individual station attributes, physical path configuration, and port-level (A/B/S/M) connection status, giving comprehensive visibility into the FDDI dual-ring topology. Its monitoring value is centered on interface/link-layer software status—tracking ring operational state, station insertion/removal, and port connection state to detect ring wraps, station faults, or cable/connector problems—rather than device-level environmental sensors like temperature or CPU load. As a standard MIB it complements the base MIB-II (RFC 1213) for generic interface counters on FDDI-attached devices. It is deployed on legacy FDDI-attached routers, switches, and end stations in older fiber-optic ring-topology network deployments. Legacy network management stations performing FDDI-SMT73-MIB SNMP polling typically walk the station and port tables on a fixed interval to catch a ring wrap or port fault as soon as it occurs.

IPNetwork Monitor allows you to monitor SNMP objects defined in FDDI-SMT73-MIB. Use the built-in SNMP Monitoring Browser to explore available variables, view their current values and descriptions, and select the objects you want to monitor. You can then create SNMP monitors, configure thresholds, and receive alerts when monitored values change.

Supported Devices

vendor-neutral, standards-based MIB, not tied to a specific manufacturer
legacy FDDI-attached router, switch, or end station

Monitoring Examples

An admin would poll a station configuration table to check overall ring status and detect whether the dual ring has wrapped (indicating a break or station failure), and check port-level entries for each of a station's A/B/S/M ports to confirm the connection state matches the expected topology. A station showing an unexpected non-operational port state would reveal a failed connector, cable, or neighboring station causing the ring to reconfigure.

What Can Be Monitored

FDDI ring operational state
station insertion/removal status
port connection state (A/B/S/M)
path configuration status
