Description: Provides management objects for D3I network interface and data communications equipment.

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 D3I-MIB?

D3I-MIB is a US Robotics (USR) vendor MIB, identifiable by the 'usr'/'nas' object-tree prefixes, for a specific network/data interface card ('D3I') used in USR's Total Control/NetServer network access server chassis. It defines an identification table capturing hardware serial numbers and revisions for both the Network Access Card (NAC) and Network Interface Card (NIC) portions of the module, plus board-manager software revision and release date, along with a separate configuration table. As a hardware/firmware inventory MIB it is used to verify exactly which card variant and firmware/hardware revision is installed in a chassis slot, supporting asset tracking, RMA/support cases, and firmware compatibility checks. It belongs to the broader USR NAS/Total Control MIB family alongside chassis and modem MIBs for the same platform. It is typically deployed on USR Total Control/NetServer access chassis in dial-up or broadband access deployments. Engineers can download the D3I-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in D3I-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

  • US Robotics Total Control/NetServer D3I network interface card

Monitoring Examples

An administrator would poll d3iIDTable / d3iIDEntry keyed by d3iIDIndex to read d3iIDNACHardwareSerNum and d3iIDNICHardwareSerNum alongside d3iIDNACHardwareRev and d3iIDNICHardwareRev to confirm exactly which hardware revision of the card is installed. d3iIDBoardManagerSwRev and d3iIDBoardManagerDate would be checked when verifying firmware compatibility before a software upgrade. The separate d3iCfgTable / d3iCfgEntry, keyed by d3iCfgIndex, holds the card's operational configuration for that slot.

What Can Be Monitored

  • NAC/NIC hardware serial numbers
  • NAC/NIC hardware revision
  • board manager software revision and date
  • per-card configuration
