Description: Eastern Research Inc. DNX E3 interface MIB for E3 (34 Mbps) port configuration and diagnostic testing on DNX devices.

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-E3-MIB?

This is an Eastern Research Inc. (ERI) enterprise MIB for the DNX product family's E3 (34.368 Mbps) interface module, covering E3 port configuration and the E1 links multiplexed within an E3 signal. It exposes per-port configuration objects (address, resource assignment, timing source, cable-length compensation) along with per-E1-link configuration nested under the E3 port, plus a command-status object for applying changes or initiating diagnostic loopback tests. Its monitoring focus is hardware/interface operational status for legacy TDM transmission equipment: timing-source and cable-length settings affect signal integrity, while the diagnostic ('Diag') branch and command-status objects allow technicians to run and check loopback tests to isolate line faults on the E3 or its constituent E1 links. It is a standalone vendor enterprise MIB with no indicated dependency on standard IETF DS3/E3 interface MIBs. It is deployed on ERI DNX cross-connect/multiplexer chassis in telecom transmission networks carrying E3/E1 TDM circuits. Engineers can download the ERI-DNX-E3-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in ERI-DNX-E3-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

  • Eastern Research Inc. (ERI) DNX digital cross-connect/multiplexer

Monitoring Examples

A technician would check e3PortConfigTable/e3PortConfigEntry, keyed by e3PortCfgAddr, reviewing e3Timing and e3ShortCable to confirm clocking source and cable-length compensation are correctly set for the E3 line, and would use e3CmdStatus to trigger and check the result of a loopback diagnostic when troubleshooting signal errors. e3E1LinkConfigTable/e3E1LinkConfigEntry, keyed by e3E1CfgLinkAddr, would be reviewed to confirm each individual E1 tributary carried within the E3 is correctly named and assigned before verifying its status downstream.

What Can Be Monitored

  • E3 port timing source configuration
  • cable length compensation setting
  • E1 sub-link configuration
  • loopback diagnostic command status
  • port resource assignment
