ERI-DNX-SMC-MIB is a vendor-specific enterprise module from ERI for managing the System Management Controller (SMC) card, which provides centralized control and monitoring within a DNX telecom chassis. It exposes a generic resource table modeling every managed resource in the system, along with its address, type, and current state, plus a set of severity-tiered alarm masks. It is explicitly a fault/status-monitoring MIB: resourceState reports the live operational state of each hardware resource, while resourceCriticalMask, resourceMajorMask, resourceMinorMask, and resourceNominalMask classify alarms by severity and resourceTrapMask controls which conditions generate SNMP traps. It is a self-contained enterprise MIB rooted under the vendor's own dnx/sysMgr OID tree rather than depending on external standards, and an operator tracing a fault often needs to know the exact ERI-DNX-SMC-MIB OID for resourceState or one of the alarm masks to configure a targeted trap filter. It is deployed on ERI DNX telecom multiplexer/chassis systems where the SMC card centrally supervises other cards and resources.

An operator would walk resourceTable/resourceEntry to enumerate every managed resource by resourceKey and resourceAddr, checking resourceType and resourceState to see whether each resource (e.g., a card or subsystem) is normal or faulted. A resourceState transitioning to a fault value combined with a set bit in resourceCriticalMask would indicate a critical hardware failure needing immediate escalation, while a resourceMinorMask hit alone might just be logged. resourceTrapMask determines whether that specific state change is forwarded as an SNMP trap to a management station in real time.
