Description: Manages Optical Transport Network (OTN) interface parameters on Infinera equipment.

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 LUM-IFOTN-MIB?

This MIB, from Infinera (formerly Lumentis, hence the LUM prefix), manages Optical Transport Network (OTN) interface parameters as defined in ITU-T Recommendation G.709, covering the OTU (Optical channel Transport Unit), ODU (Optical channel Data Unit), OPU (Optical channel Payload Unit), and TP (Tributary Port) layers of the OTN framing hierarchy. It exposes general configuration and state last-change timestamps along with table-size objects for each OTN layer, letting an operator track how many OTU/ODU/OPU/TP entities are configured and when their configuration or operational state last changed. Its monitoring value is squarely in optical transport software/protocol state—detecting when OTN layer configuration or state changed (a potential indicator of a fault, reconfiguration, or link flap at the optical framing level) and confirming the expected number of provisioned optical channel entities—complementing lower-level optical hardware telemetry (power/temperature) that would live in the related LUM-IFSMTCMPM-MIB. It explicitly depends on and cross-references LUM-IFSMTCMPM-MIB for Section/Path Monitoring and Tandem Connection Monitoring detail, and is built on ITU-T G.709/G.798/G.806 standards. It would be deployed on Infinera DWDM/OTN transport platforms in service provider and long-haul optical backbone networks. Engineers can download the LUM-IFOTN-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in LUM-IFOTN-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

  • Infinera DWDM/OTN optical transport platform

Monitoring Examples

An operator would check ifOtnGeneralIfOtnOtuTableSize and ifOtnGeneralIfOtnOduTableSize to confirm the expected number of OTU and ODU entities are provisioned on a given line card, and monitor ifOtnGeneralIfOtnOtuStateLastChangeTime/ifOtnGeneralIfOtnOduStateLastChangeTime to detect recent, potentially unplanned state transitions at those layers—an early indicator of an optical link fault. ifOtnGeneralIfOtnOpuTableSize and ifOtnGeneralIfOtnTpTableSize similarly confirm payload and tributary port entity counts match provisioning expectations. A recent, unexpected update to ifOtnGeneralConfigLastChangeTime alongside a state change would prompt investigation into whether a technician or automated process altered the OTN configuration.

What Can Be Monitored

  • OTU/ODU/OPU/TP entity counts
  • OTN layer configuration last-change time
  • OTN layer state last-change time
