Description: Manages Motorola Broadband DOCSIS cable modem provisioning, registration, and downstream statistics.

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 SDM-MIB?

SDM-MIB supports Motorola's SmartStream Device Manager (SDM), a network element/event management component historically associated with Motorola broadband and cable infrastructure products. Rather than exposing raw hardware counters, its objects model management events about other devices in the network: a probable cause code and descriptive text, the affected object's name, type, IP address, and category, plus a reference URL for more detail. Its monitoring value is therefore primarily fault/status oriented, letting an operator see which devices SDM has flagged and why, effectively acting as an alarm/event correlation feed layered on top of whatever device-specific status MIBs generate the underlying counters. It depends conceptually on the identity/addressing conventions of the devices it describes but is not shown to import other management MIBs directly in this excerpt. It is typically deployed within a Motorola broadband network management system monitoring cable modems, headend, or other broadband access equipment for operational faults. Engineers can download the SDM-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in SDM-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

  • Motorola broadband/cable network element (e.g. cable modem or headend equipment) managed via SmartStream Device Manager

Monitoring Examples

An operator would poll sdmObjectName, sdmObjectType, and sdmObjectIPAddress to identify which managed device an alert refers to, then read sdmProbableCause and sdmProbableCauseText (with sdmProbableCauseName) to understand the nature of the problem, such as a loss-of-signal or provisioning failure. The sdmCategory object lets alerts be grouped by class of issue, and sdmUrl can point to a management console page with further remediation detail. A spike in probable-cause events tagged against the same sdmObjectIPAddress would indicate a persistently misbehaving device worth escalating.

What Can Be Monitored

  • probable cause of reported faults
  • affected device name/type/IP address
  • event category
  • reference URL for event detail
