Description: Monitors STM-1/OC-3 SONET/SDH optical interface performance and alarm state in ERI DNX access systems.

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 ERI-DNX-STM1-OC3-MIB?

ERI-DNX-STM1-OC3-MIB is an ERI (Electronic Research, Inc.) enterprise MIB for the DNX digital cross-connect product line, specifically for STM-1/OC-3 SONET/SDH optical interface cards. It exposes optical device configuration data (device address/resource identifiers, device type, multiplexing mode, line timing source, payload mapping across up to three payload slots) and diagnostic/command-status objects, along with timeslot allocation information. Its monitoring purpose centers on hardware status of the optical interface: confirming the correct multiplex mode and line timing are active, that payload mapping matches provisioning, and that the optical device's command/diagnostic status is healthy, which are key indicators of SONET/SDH transport health. As a SONET/SDH-related MIB it conceptually aligns with (though does not necessarily directly import) standard SONET-MIB constructs for optical line/section monitoring. It is typically deployed in telecom transport networks using ERI DNX access/cross-connect systems carrying STM-1/OC-3 optical circuits. Engineers can download the ERI-DNX-STM1-OC3-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in ERI-DNX-STM1-OC3-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

ERI DNX SONET/SDH cross-connect access system
STM-1/OC-3 optical interface card

Monitoring Examples

An administrator would poll opticalDevConfigTable to check optDevType and optDevMultiplexMode against the expected STM-1 or OC-3 configuration, and optLineTiming to confirm the interface is deriving timing from the correct source. The optDevCmdStatus field reveals whether a configuration or diagnostic command on the optical device succeeded or failed. Mismatched optDevPayload1/2/3 mappings versus optDevTsAlloc timeslot allocation would indicate a provisioning error causing traffic misrouting on the SONET circuit.

What Can Be Monitored

optical device type/multiplex mode
line timing source

device command/diagnostic status

How to Use in IPNetwork Monitor

Example using optMapperPathLOPErrs OID:

Select an Eastern Research Inc. (ERI) DNX digital cross-connect/multiplexer (STM-1/OC-3 optical interface card) 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 optMapperPathLOPErrs into the Find box to locate it in the OID tree, then select it and click OK. This is the total number of Mapper Path Loss of Pointer Errored Seconds. 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.
