Description: Eastern Research Inc. DNX link test MIB for performing BERT and loopback diagnostics on DSx1 and high-speed ports.

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-LINK-TEST-MIB?

ERI-DNX-LINK-TEST-MIB is an Eastern Research Inc. (ERI) enterprise MIB for the DNX digital cross-connect/multiplexer product line, providing on-demand diagnostic testing of DS1 (T1) and high-speed (HS) ports via bit-error-rate testing (BERT) and loopback control. It exposes a test table where each entry configures and reports on a diagnostic session for a given link: the type of loopback (line or backplane), BERT test state, requested test duration, and resulting error statistics. Its monitoring emphasis is on hardware/link-quality status: bit errors and errored-seconds counts (both local and remote) collected during a BERT run directly indicate the physical health of a T1/HS circuit, letting a technician confirm whether a suspect link is clean or actively corrupting data. It is specific to ERI's DNX product architecture and depends on standard DS1 bit-error/errored-second terminology for its measurement semantics, though it defines its own vendor test-control objects rather than extending an IETF test table directly. It is deployed on Eastern Research DNX digital cross-connect systems in telecom central offices or enterprise WAN environments for circuit-level fault diagnosis. Engineers can download the ERI-DNX-LINK-TEST-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in ERI-DNX-LINK-TEST-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 systems

Monitoring Examples

A technician would create/configure a dsx1TestTable/dsx1TestEntry row, indexed by dsx1TestLinkAddr and dsx1TestResrcId, setting dsx1TestLinkLoop or dsx1TestBackplnLoop to place the port in loopback, then set dsx1TestBertState to start a BERT run for dsx1TestDuration seconds. After the test, reading dsx1TestBitErrs, dsx1TestESs, and dsx1TestRemoteESs reveals whether the circuit accumulated bit errors or errored seconds locally and remotely, distinguishing a clean link from one with a physical-layer fault. dsx1TestLinkState shows whether the port is currently in-service, out-of-service, or under test, which is important context before interpreting the error counters.

What Can Be Monitored

  • BERT test state and duration
  • loopback mode (line/backplane)
  • bit error count
  • local/remote errored seconds
  • link/port test state
