Description: TIMETRA-ETH-RING-MIB module

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 TIMETRA-ETH-RING-MIB?

This Nokia/Alcatel-Lucent proprietary MIB manages Ethernet Ring Protection Switching rings on the 7750 SR SROS platform, a Layer-2 resiliency technology for looped Ethernet topologies. It exposes ring configuration objects (ring index, description, guard time, revert time) alongside operational and administrative state for each ring instance. It's directly useful for monitoring the software health of the ring protocol itself: tmnxEthRingAdminState and tmnxEthRingOperState reveal whether a ring is administratively enabled and actually passing traffic, while the revert timers show whether a ring is mid-recovery after a fault. As a Nokia SROS extension it builds on the vendor's common textual-convention MIB and relates to the underlying Ethernet/interface MIBs for the physical ports carrying the ring. It's typically deployed in metro Ethernet and carrier access networks using 7750 SR/7450 ESS nodes arranged in ring topologies for fast failover, where TIMETRA-ETH-RING-MIB SNMP monitoring confirms ring state during protection-switching events.

IPNetwork Monitor allows you to monitor SNMP objects defined in TIMETRA-ETH-RING-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

  • Nokia/Alcatel-Lucent 7750 SR
  • 7450 ESS metro Ethernet switch/router

Monitoring Examples

An operator polls tmnxEthRingConfigTable / tmnxEthRingConfigEntry indexed by tmnxEthRingIndex to compare tmnxEthRingAdminState against tmnxEthRingOperState -- a ring administratively up but operationally down indicates a break or misconfigured guard/revert timing. Watching tmnxEthRingRevertTimeCountDn during a tmnxEthRingRevertTime window shows whether the ring is actively counting down to revert to its idle topology after a fault has cleared, and tmnxEthRingTimeStamp records when the ring's state last changed for correlation with other network events.

What Can Be Monitored

  • ring administrative state
  • ring operational state
  • guard time
  • revert time countdown
  • ring last-changed timestamp
