Description: Monitors FDDI optical interface statistics on SynOptics LANplex switch modules.

Start monitoring vendor-neutral, standards-based MIB, any SNMPv3-capable network device (SNMP engine identity/boot/clock status) with a free 30-day trial of IPNetwork Monitor. Import MIBs, browse SNMP OIDs, create custom SNMP monitors, configure alerts, and monitor any SNMP-enabled network device from a single console.

What Is LANPLEX-OPT-FDDI-MIB-1-1-2?

LANPLEX-OPT-FDDI-MIB-1-1-2 is a SynOptics (later Bay Networks) enterprise MIB for the LANplex modular switch/hub platform, covering FDDI (Fiber Distributed Data Interface) optical interface modules. It exposes physical/optical FDDI port-level data such as link and ring state and interface statistics for the fiber ring interfaces installed in a LANplex chassis. Its practical monitoring value is squarely on hardware status of the FDDI optical modules: whether a port is optically connected, its ring state, and its error/frame counters, rather than higher-level protocol behavior. It builds on standard FDDI MIB concepts (as later formalized in RFC 1512) tailored to SynOptics' modular chassis hardware. It would have been deployed in early-to-mid 1990s campus backbone networks using FDDI dual-ring fiber for LANplex chassis interconnection. Network engineers evaluating or troubleshooting this functionality can download the LANPLEX-OPT-FDDI-MIB-1-1-2 file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in LANPLEX-OPT-FDDI-MIB-1-1-2. 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.

Monitoring Examples

The source material provided no extracted sample object names for this MIB, so specific object identifiers cannot be grounded here. In general terms, an admin would poll this MIB's FDDI optical interface table for port link/ring status and error counters to detect a failed or degraded fiber connection on a LANplex FDDI module.

What Can Be Monitored

FDDI optical port link status
FDDI ring state
interface error/frame counters
