Import MIBs, browse SNMP OIDs, create custom SNMP monitors, configure alerts, and monitor any SNMP-enabled network device from a single console.

What Is CTSMTMIB-MIB?

This MIB is Cabletron Systems' implementation of FDDI Station Management (SMT) objects, used to manage and monitor Fiber Distributed Data Interface (FDDI) ring stations on Cabletron networking equipment. It exposes a station table with per-station identity and status information, including dual-homing state and the associated wrap-LED indicator status for redundant ring attachments. For hardware status monitoring, it specifically covers the health of dual-homed connections, letting an operator detect a failed or degraded backup path on a dual-attached FDDI station before it causes a full outage. It builds on the standard FDDI SMT model (ANSI X3T9.5 / RFC 1512 FDDI-SMT-MIB), adapted into Cabletron's proprietary agent. Typically deployed on legacy Cabletron FDDI concentrators/switches in dual-ring campus backbone networks. Network engineers evaluating or troubleshooting this functionality can download the CTSMTMIB-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in CTSMTMIB-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

Cabletron FDDI concentrators/switches
FDDI dual-attached stations

Monitoring Examples

An operator would poll ctsmtmibSMTTable/ctsmtmibSMTEntry indexed by ctsmtmibSmtIndex to enumerate each FDDI station's SMT status, then check ctsmtmibSMTDualHomeStatus to confirm whether the station is properly dual-homed to both primary and secondary concentrators. ctsmtmibSMTDualHomeWrpLEDStatus mirrors the physical front-panel wrap LED, so a mismatch between the reported status and the expected state reveals a failed backup ring connection needing physical inspection.

What Can Be Monitored

FDDI dual-home connection status
backup ring wrap LED state
SMT station identity/index
ring redundancy health
