What Is BRCM-CABLEDATA-MGMT-MIB?
BRCM-CABLEDATA-MGMT-MIB is a Broadcom-authored MIB module for managing the operational configuration and status of Broadcom-chipset-based DOCSIS cable data devices such as cable modems and related residential gateway hardware. It groups its objects into a base management area and a vendor-extension area, exposing configuration and operational status data specific to the cable data function of the device. Its monitoring relevance centers on device operational/software status for the cable interface - confirming the cable data subsystem is up and correctly configured is the kind of health check this MIB supports, complementing DOCSIS-standard counters with Broadcom-specific detail. It depends on the broader DOCSIS/cable-modem MIB framework (e.g., DOCS-CABLE-DEVICE-MIB and related IETF cable MIBs) for core interface and RF statistics, supplying only the Broadcom-specific management layer on top. In an NMS's loaded MIB set, the BRCM-CABLEDATA-MGMT-MIB module is typically enabled alongside the standard DOCSIS MIBs to add Broadcom-specific configuration detail to a cable modem's management data. It is deployed on cable modems, embedded MTAs, and gateway devices built around Broadcom DOCSIS silicon in cable broadband access networks.
IPNetwork Monitor allows you to monitor SNMP objects defined in BRCM-CABLEDATA-MGMT-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.
What Can Be Monitored
- cable data subsystem operational status
- cable data base configuration
- Broadcom vendor-specific cable settings
Supported Devices
- Broadcom-chipset DOCSIS cable modems and residential gateways
Monitoring Examples
An administrator would poll objects under cableDataMgmtMIBObjects/cableDataMgmtBase to check the cable data subsystem's operational configuration status, and cableDataMgmtVendor for Broadcom-specific extensions not covered by the standard DOCSIS MIBs. An unexpected value in these base management objects would typically indicate a misconfiguration or fault in the cable-modem's data-path management rather than a physical-layer RF problem, which standard DOCSIS MIBs would cover separately.
