What Is NNCEXTSPVC-MIB?

NNCEXTSPVC-MIB is Alcatel CID's proprietary MIB, associated with the Newbridge/Alcatel multiservice switch family, for managing Soft Permanent Virtual Connections (SPVCs) across ATM, Frame Relay, and Circuit Emulation network endpoints. It exposes objects for creating, modifying, querying, and deleting SPVCs, including Permanent Virtual Path/Channel Connections (PVPC/PVCC) for Cell Relay endpoints and SPVCCs for Frame Relay and Circuit Emulation. It is used in monitoring to track the operational and provisioning status of virtual circuits — verifying configured SPVCs are correctly set up, active, and torn down as expected — which is central to fault detection in ATM/Frame Relay transport networks. As an extension to core ATM/Frame Relay connection management, it likely depends on standard ATM-MIB or Frame Relay DTE MIB conventions for underlying interface and VPI/VCI addressing. It is typically deployed in carrier or enterprise WAN environments using Alcatel/Newbridge ATM switches to provision and monitor soft PVCs across a multi-service transport network. Engineers can download the NNCEXTSPVC-MIB file directly to load it into their MIB browser.

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

  • Alcatel/Newbridge ATM/Frame Relay switch

Monitoring Examples

An operator managing SPVCs would query the connection status objects for a given PVPC or PVCC endpoint to confirm the soft permanent virtual connection has been successfully established end-to-end, and monitor for unexpected teardown or failure states. Because specific object/table names were not present in the sample data, this example is grounded directly in the module's documented scope of creating, modifying, querying, and deleting SPVCs on Cell Relay, Frame Relay, and Circuit Emulation endpoints.

What Can Be Monitored

  • SPVC connection status (established/torn down)
  • PVPC/PVCC endpoint state
  • Frame Relay and Circuit Emulation SPVCC status
