What Is TPLINK-ETHERNETOAMEVENTLOG-MIB?

This is a TP-Link private MIB for logging Ethernet OAM (802.3ah) event history on TP-Link managed switches, recording link-level OAM events such as link faults and errored-symbol/errored-frame notifications over time. No module description or sample objects were available in this batch, but based on its short description it would expose an event-log table of OAM error events with timestamps and error counters. It supports monitoring of hardware/link fault history, letting an admin review past link-level errors (rather than just current state) to identify intermittent physical-layer problems on a port. It builds on the IEEE 802.3ah Ethernet OAM standard's event-notification model, similar in spirit to the base Ethernet OAM MIB, though the exact dependency isn't visible from the available data. It is typically deployed on TP-Link managed switches for after-the-fact diagnosis of intermittent link problems reported by users, and a TPLINK-ETHERNETOAMEVENTLOG-MIB download is usually the first step toward loading it into a MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in TPLINK-ETHERNETOAMEVENTLOG-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

TP-Link managed Ethernet switches

Monitoring Examples

No specific object names were available in the sampled data, so a concrete OID-level example cannot be honestly constructed; based on the module's stated purpose, an admin would generally expect to poll an OAM event-log table to review historical link-fault and error-frame events per port. Direct inspection of the raw MIB source would be needed to identify the actual table and object names for a precise monitoring scenario.

How to Use in IPNetwork Monitor

Example using ethernetOamEventLogStatLocalSymbolPeriod OID:

Select a TP-Link managed Ethernet switch (OAM link-fault event-log history 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 ethernetOamEventLogStatLocalSymbolPeriod 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. Displays the number of error-symbol-period link events occurred on the local link. 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 between polls, since a rising count of errors, failures, or discards often points to a real underlying problem. Click Finish to create the monitor; you can adjust any parameter later.
