Description: Bellcore intercarrier Frame Relay MIB (RFC 2233 related) defining SNMP objects for inter-provider Frame Relay service monitoring.

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 INTERCARRIER-FR-MIB?

INTERCARRIER-FR-MIB is a Bellcore/Telcordia MIB, related to the RFC 2233 era of Frame Relay standards work, defining generic objects for describing Intercarrier Frame Relay Network Service. It is intended to expose data about Frame Relay service as it crosses handoff points between different carrier networks. Based on its purpose, it would monitor circuit/service-level status and performance at carrier interconnection points, though no specific object or table names were available in this excerpt to confirm exact fields. It relates to the broader family of standard Frame Relay MIBs (such as the DTE-side Frame Relay MIB defined in RFC 2115) extended to cover intercarrier service handoffs. It would typically be deployed on carrier-grade network equipment at points where Frame Relay circuits are exchanged between different service provider networks. Engineers can download the INTERCARRIER-FR-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in INTERCARRIER-FR-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

vendor-neutral, standards-based MIB, not tied to a specific manufacturer
carrier-grade Frame Relay network equipment

Monitoring Examples

No sample object or table names were provided in the source excerpt, so specific polling targets cannot be honestly cited. Based on the module description, this MIB would define generic objects for tracking the status of Frame Relay circuits at intercarrier handoff points, useful for monitoring service continuity across provider boundaries, but concrete object names aren't available here.
