Description: Manages the Cisco/Scientific Atlanta GX2 Dm870 downstream modulator and optical node module in HFC networks.

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 OMNI-gx2Dm870-MIB?

OMNI-gx2Dm870-MIB is a private MIB (built on GX2HFC-MIB, HFC — Hybrid Fiber-Coax cable-plant monitoring family) reporting nominal-vs-current parameters for the gx2Dm870 module, likely an RF/optical monitoring probe. Its analog table records, per monitored parameter, a label/unit-of-measure, major/minor high/low alarm limits, current value, state flag, min/max observed value, and alarm state, with parallel digital and counter (Cnt) tables, plus status and factory tables. As a performance/hardware-status MIB it lets a cable operator watch an HFC plant parameter (e.g., RF level) against nominal alarm thresholds. It is deployed on this vendor's HFC cable-plant monitoring probes (gx2Dm870 module). Engineers can download the OMNI-gx2Dm870-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in OMNI-gx2Dm870-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

  • General Instrument OmniStar GX2 HFC headend/optical node (gx2Dm870 RF/optical monitoring probe module)

Monitoring Examples

A cable operator checks dm870currentValueOffsetNomMonitor against dm870majorLowOffsetNomMonitor to catch an HFC plant parameter drifting toward an alarm threshold on a gx2Dm870 monitoring probe.

What Can Be Monitored

  • monitored parameter current value vs. nominal alarm thresholds
