Description: Defines SNMP trap notifications for fault and event reporting on CommWorks broadband 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 USR-TRAP-MIB?

USR-TRAP-MIB is a vendor-specific SNMP module originally from U.S. Robotics/CommWorks defining trap notifications for fault and event reporting on CommWorks broadband access equipment (e.g. modem/remote-access concentrators). Its only confirmed content in the available source is the "usr" enterprise OID branch under which the vendor's trap and object definitions are rooted; the specific fault/event traps themselves are defined using this branch as their base. As a trap-oriented module it is used for fault monitoring - alerting on abnormal conditions or events on the equipment - rather than exposing polled hardware performance counters like temperature or CPU load directly, though the underlying traps would typically flag conditions such as line faults, port failures, or configuration issues. No other MIB dependency is evident beyond the standard SNMP notification framework and the vendor's own OID registration. Typical deployment context is legacy USR/CommWorks broadband remote-access or modem-bank equipment in telecom/ISP environments. Engineers can download the USR-TRAP-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in USR-TRAP-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

  • U.S. Robotics/CommWorks broadband access equipment (modem/remote-access concentrator)

Monitoring Examples

With only the "usr" root OID confirmed in the available sample objects, this module's specific trap objects (fault codes, event descriptions) are not directly enumerated in the source material; a network management station would subscribe to traps rooted under the "usr" enterprise branch to receive fault notifications from CommWorks equipment. Without further object detail, a more specific polling scenario cannot be responsibly constructed. This entry should be treated as based on limited available data pending fuller module content.

What Can Be Monitored

  • fault/event trap notifications (specific trap types not detailed in available source)
