Description: Manages Transition Networks Ethernet OAM performance monitoring session metrics.

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 TN-ETHSOAM-PM-MIB?

TN-ETHSOAM-PM-MIB is a Transition Networks proprietary MIB (extending TN-ETHSOAM-MIB/TN-EVC-MIB) implementing Performance Monitoring for Ethernet Services OAM (Y.1731-style loss/delay measurement). Its session-configuration table records session type, mode, storage mode, and interval, a transfer-configuration table sets when/how collected data is uploaded to a server (schedule hours/minutes/offset, random offset, server address, interval mode/number, include-incomplete flag), and a loss-measurement (LM) history-stats table records interval end time, elapsed time, and transmitted-count per historical interval. As a performance MIB it lets an administrator confirm PM sessions are scheduled correctly and review historical frame-loss statistics for an Ethernet service. It is deployed on Transition Networks carrier Ethernet platforms implementing Ethernet Services OAM PM. Engineers can download the TN-ETHSOAM-PM-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in TN-ETHSOAM-PM-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

  • Transition Networks carrier Ethernet platforms (Ethernet Services OAM PM)

Monitoring Examples

An administrator reviews tnEthSoamPmLmHistoryStatsTxCount across recent intervals to assess frame-loss trends for a monitored Ethernet service on a Transition Networks platform.

What Can Be Monitored

  • PM session configuration and historical loss-measurement statistics

How to Use in IPNetwork Monitor

Example using tnEthSoamPmLmHistoryStatsTxCount OID:

Select a Transition Networks carrier Ethernet platform (Ethernet Services OAM performance-monitoring session 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 tnEthSoamPmLmHistoryStatsTxCount 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. This object contains the number of outbound frames in this MEP for this Measurement Interval. 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 Counter64-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.
