Description: TIMETRA-ETH-TUNNEL-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-TUNNEL-MIB?

TIMETRA-ETH-TUNNEL-MIB is an Alcatel-Lucent (Nokia) MIB for the SROS operating system used on their service router platforms, defining management objects for Ethernet Tunnel components -- a link-aggregation-like construct that bundles multiple member ports/LAGs into a protected Ethernet tunnel with configurable protection switching behavior. It exposes both configuration data (tunnel protection type, hold-down/hold-up timers for members, revert time, row status) and operational state through a separate operational table reflecting the tunnel's actual runtime status. Its monitoring value lies in tracking the software/protocol status of the tunnel's protection-switching state machine -- confirming whether the primary or protection path is currently active and whether a member is flapping due to hold-timer misconfiguration -- important for services relying on sub-second Ethernet resiliency. It is deployed as part of the broader TIMETRA/SROS MIB family and depends on Alcatel-Lucent's own indexing conventions for physical/logical port members rather than IETF LAG standards directly. It is typically used in carrier and enterprise networks running Alcatel-Lucent 7750/7450-class service routers for Ethernet transport resiliency. Network engineers evaluating or troubleshooting this functionality can download the TIMETRA-ETH-TUNNEL-MIB file directly to load it into their MIB browser.

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

  • Alcatel-Lucent (Nokia) 7750/7450-series SROS service routers

Monitoring Examples

An administrator would poll tmnxEthTunnelConfigTable/tmnxEthTunnelConfigEntry for a given tmnxEthTunnelIndex to check tmnxEthTunnelProtectionType and tmnxEthTunnelRevertTime, then cross-check tmnxEthTunnelOperTable/tmnxEthTunnelOperEntry to confirm the tunnel's actual operational/active member state. A tunnel whose operational table shows the standby member active longer than expected, combined with tmnxEthTunnelHoldDownTimeMember/tmnxEthTunnelHoldUpTimeMember settings that are too aggressive, would explain repeated protection switchovers (flapping) on that tunnel.

What Can Be Monitored

  • Ethernet tunnel protection type
  • tunnel member hold-down/hold-up timers
  • tunnel revert time
  • tunnel configuration change timestamp
  • tunnel operational/active state

How to Use in IPNetwork Monitor

Example using tmnxEthTunnelApsMemberActCount OID:

Select an Alcatel-Lucent (Nokia) 7750/7450-series SROS service router (Ethernet tunnel protection-switching status) as the target host to create a monitor — the SNMP service should be up and running on it. Click New Monitor, then check SNMP Custom on the Favorites tab, click Next, and confirm the host. On the next page, click Select... to open the built-in SNMP MIB Browser and type tmnxEthTunnelApsMemberActCount into the Find box to locate it in the OID tree, selecting the specific row/instance you want to monitor since this is a table column, then select it and click OK. The value of tmnxEthTunnelApsMemberActCount indicates the number of times, since system startup, that the Ethernet Tunnel Group member has been active. On the monitor's Main parameters page you can set the target's SNMP port (default 161), credentials, polling interval, and other settings — see the SNMP Monitor help for details. On the State conditions and Alerting tabs, configure when the monitor should change state and trigger an alert; since this is a Counter32-type OID, Value bounds is the most useful condition here — trigger an alert if the counter increases sharply between polls relative to its normal baseline, since an unexpected spike often reflects a real change in traffic or activity. Click Finish to create the monitor; you can adjust any parameter later.
