CISCO-ALARM-MIB

Description: Provides generic alarm management including alarm table and notification control on Cisco devices.

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.

CISCO-ALARM-MIB defines a generic, cross-platform alarm-management framework for Cisco devices, providing a common active-alarm table and notification mechanism usable by many different hardware and software subsystems. It exposes fault/alarm data — a list of currently active alarms, each tied to a specific interface (via ifIndex) or physical entity (via entPhysicalIndex), with an alarm type, timestamp, severity, current status, and whether the alarm is service-affecting. This is fundamentally a faults/status MIB used to monitor overall device health: by walking the active-alarm table an operator gets a consolidated view of every current hardware or software fault, its severity, and whether it is impacting service, rather than polling many separate subsystem-specific MIBs individually. It explicitly ties alarm entries back to the standard IF-MIB (ifIndex) and ENTITY-MIB (entPhysicalIndex) for locating the affected interface or physical component. It is deployed broadly across Cisco platforms as a common alarm-surfacing layer, useful in NOC/EMS environments that need a single alarm feed per device. Network engineers evaluating or troubleshooting this functionality can download the CISCO-ALARM-MIB file directly to load it into their MIB browser.

An operator polls coiAlarmActiveTable/coiAlarmActiveEntry indexed by coiAlarmIndex and filters on coiAlarmSeverity and coiAlarmServiceAffecting to prioritize which active faults need immediate attention. coiAlarmObjectEntPhyIndex or coiAlarmObjectIfIndex identifies exactly which physical component or interface raised the alarm, coiAlarmType and coiAlarmObjectName describe what kind of fault occurred, and coiAlarmTimeStamp shows when it started — for example, spotting a service-affecting alarm on a specific power-supply entity that has been active for an extended period.

Cisco SNMP MIB for managing and monitoring alarms on physical entities (fans, power supplies, modules) in network devices, providing alarm filtering, notifications, and status tracking.
