What Is USR-ATMCFG-MIB?
USR-ATMCFG-MIB is a vendor-specific enterprise module from US Robotics/CommWorks (later part of 3Com) that defines configuration objects for ATM interfaces, including traffic contracts and service categories, on CommWorks carrier-class access/gateway equipment. It exposes configuration data governing how ATM virtual circuits are provisioned, such as traffic class (CBR, VBR, UBR) and associated bandwidth parameters, rather than raw performance counters. Its role in hardware/software status monitoring is centered on confirming ATM interface configuration correctness, letting an administrator verify that a circuit's provisioned traffic contract matches the intended service level and detect misconfigured parameters that could cause a circuit to be rejected or under-provisioned. It likely complements standard ATM-MIB (RFC 2515) concepts for interface and PVC status, though implemented as a CommWorks-proprietary extension. It is typically deployed on CommWorks/3Com carrier access equipment providing ATM-based broadband or voice/data aggregation services. Engineers can download the USR-ATMCFG-MIB file directly to load it into their MIB browser.
IPNetwork Monitor allows you to monitor SNMP objects defined in USR-ATMCFG-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
- CommWorks/3Com ATM access or aggregation gateway
Monitoring Examples
An administrator would check ATM interface and traffic-contract configuration objects in this MIB to confirm a given virtual circuit is provisioned with the correct service category (e.g., CBR vs UBR) and bandwidth parameters for its intended traffic type. A mismatch between the configured traffic contract and observed cell loss or discard behavior (tracked via companion ATM statistics objects) would reveal an under-provisioned circuit causing service degradation. No sample objects were provided for this MIB, so this description is grounded in its stated configuration purpose.
What Can Be Monitored
- ATM interface configuration
- traffic contract/service category settings
- provisioned bandwidth parameters
