Description: Manages the Cisco/Scientific-Atlanta GX2 DRT4X downstream RF transmitter card in HFC optical node deployments.

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-gx2drt4x-MIB?

OMNI-gx2drt4x-MIB is a vendor-specific SNMP module from Cisco/Scientific-Atlanta for the GX2 DRT4X, a downstream RF transmitter card used in HFC optical node deployments. It exposes hardware status and configuration data for the RF transmitter card, such as per-port transmit levels, card identity, and operational state, rather than general networking or software data. Its key monitoring purpose is hardware health: surfacing whether the card is present and operating normally, and flagging abnormal RF transmit power that could indicate a failing amplifier or transmitter component. It likely shares indexing and structural conventions with a common GX2 chassis/platform MIB used across the OMNI GX2 card family. It is deployed in cable/MSO HFC networks where optical nodes are remotely monitored via SNMP for outside-plant reliability. Engineers can download the OMNI-gx2drt4x-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in OMNI-gx2drt4x-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 (GX2 DRT4X downstream RF transmitter card)

Monitoring Examples

No sample objects were provided, so specific object names cannot be quoted directly. Based on the module's purpose, monitoring would typically center on a per-port RF transmit level and card status table indexed by slot/port, similar to other GX2 line card MIBs. An engineer would poll such data to detect a transmitter port whose output power has drifted out of tolerance, an early sign of amplifier degradation that could disrupt downstream video/data service. The lack of concrete sample objects means this remains a plausible but unverified scenario.

What Can Be Monitored

  • card presence/insertion status
  • RF transmit power level
  • port operational status
  • card operating state
