Category: Network Interfaces, SNA and Legacy Protocols, Vendor: 3Com

Description: Manages Chipcom (3Com) FDDI (Fiber Distributed Data Interface) network interface configuration and ring statistics.

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 CHIPFDDINET-MIB?

CHIPFDDINET-MIB is a legacy Chipcom (later acquired by 3Com) enterprise MIB for managing FDDI (Fiber Distributed Data Interface) network modules and ports within Chipcom's Online (chassis-based) networking platform. It exposes per-module and per-port FDDI statistics: management receive/transmit errors, backplane errors, PLL (phase-locked loop) unlock errors, and link-confidence-test (LCT) failure counts. Its monitoring value is squarely hardware status of FDDI ring interfaces, surfacing physical-layer faults such as clock-recovery (PLL) problems or backplane communication errors that indicate a failing module or port before the FDDI ring degrades or wraps. Given the FDDI subject matter, it likely parallels concepts from the standard FDDI-MIB (RFC 1512) while adding Chipcom's chassis/slot-indexed module structure. It would have been deployed in legacy Chipcom Online chassis switches/concentrators used in FDDI backbone rings, now obsolete equipment found mainly in legacy inventories. Engineers can download the CHIPFDDINET-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in CHIPFDDINET-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.

Monitoring Examples

An admin would poll olFDDIStatsModTable (olFDDIStatsModSlotIndex, olFDDIStatsModMgtRcvErrs, olFDDIStatsModMgtXmitErrs, olFDDIStatsModBackplaneErrs, olFDDIStatsModPllUnlockErrs) to identify a specific slot module accumulating PLL unlock or backplane errors, indicating failing hardware. olFDDIStatsPortTable (olFDDIStatsPortSlotIndex, olFDDIStatsPortIndex, olFDDIStatsPortLCTFailCts) narrows the fault to a specific port, where a rising LCT failure count would indicate a degrading fiber link or transceiver on that FDDI port.

What Can Be Monitored
