What Is USR-ATM-CROSS-CONNECT-MIB?

USR-ATM-CROSS-CONNECT-MIB is a CommWorks (US Robotics/3Com) enterprise MIB for managing ATM cross-connect switching on their carrier-class access equipment, controlling how virtual circuits are switched between ATM ports using VPI/VCI values. It exposes configuration data describing cross-connect table entries that map an incoming VPI/VCI on one port to an outgoing VPI/VCI on another. Its monitoring role is configuration/software-state oriented: confirming that cross-connect mappings are correctly provisioned and active, which helps diagnose a broken end-to-end ATM circuit caused by a missing or incorrect cross-connect entry rather than a physical link fault. It is closely tied to standard ATM PVC/VCC concepts (ATM Forum and related IETF ATM MIBs) even though it is a vendor-specific extension for CommWorks hardware. It is deployed on CommWorks/3Com ATM switching platforms used by carriers for ATM-based access and aggregation networks. Engineers can download the USR-ATM-CROSS-CONNECT-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in USR-ATM-CROSS-CONNECT-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.

Monitoring Examples

No sample object names were supplied for this module in the input data; based on its description, one would expect a cross-connect table keyed by port/VPI/VCI pairs describing the switched path between ATM interfaces. An administrator would poll such a table to verify a specific cross-connect entry exists and is active, explaining an end-to-end ATM circuit outage if the entry is missing, misconfigured, or in a down state.
