Import MIBs, browse SNMP OIDs, create custom SNMP monitors, configure alerts, and monitor any SNMP-enabled network device from a single console.

What Is ATT-CNM-FRAME-RELAY-MIB?

ATT-CNM-FRAME-RELAY-MIB is a vendor MIB developed for AT&T's Customer Network Management (CNM) service, giving customers visibility into Frame Relay permanent virtual circuit (PVC) status and committed information rate (CIR) utilization for their leased circuits. It focuses on connection/circuit-level configuration and performance data rather than device hardware sensors. Its monitoring value is confirming a given PVC is active and identifying whether traffic on it is exceeding its committed rate, functioning as a software/service-status view into the carrier's frame relay network. It layers on top of the standard Frame Relay DTE/DCE interface MIB concepts used across the industry. It was typically deployed in AT&T CNM portals/tools used by enterprise customers during the era when frame relay was a common WAN service, with the ATT-CNM-FRAME-RELAY-MIB MIB serving as the reference for confirming PVC status and CIR utilization.

IPNetwork Monitor allows you to monitor SNMP objects defined in ATT-CNM-FRAME-RELAY-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 object names were supplied for this MIB, so a specific table cannot be cited. Conceptually, an admin would check a PVC's status object for an active versus down state and monitor a CIR utilization counter to see whether traffic on that virtual circuit is running above its committed rate.
