Description: Monitors Nokia hardware module inventory, operational status, and fault state for network elements.

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 NOKIA-HWM-MIB?

NOKIA-HWM-MIB is a Nokia Hardware Management MIB used to track the inventory and operational status of hardware modules (units and slots) within Nokia network elements. It exposes per-unit tables covering administrative and operational state, availability status, LED indicator state, serial number, and production date, along with a corresponding slot table for physical placement tracking. This MIB is directly focused on hardware status monitoring: it reports whether each hardware unit is administratively enabled and operationally up, its availability status, and its LED state, and it even supports a remote restart action for fault recovery. It is a common infrastructure MIB likely referenced by, or working alongside, other Nokia network-element-specific hardware and role MIBs (such as NOKIA-COMMON-NE-ROLE-MIB) for full network element context. It is typically deployed in Nokia carrier network elements where operators need real-time visibility into card/module health and slot occupancy. Engineers can download the NOKIA-HWM-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in NOKIA-HWM-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

An administrator would poll ntcHWUnitTable (via ntcHWUnitEntry) to check ntcHWAdminState and ntcHWOperState for each hardware unit, flagging any unit that is administratively enabled but operationally down. The ntcHWAvailabilityStatus object reveals degraded conditions such as a hardware unit running with an internal fault, while ntcHWLedState mirrors the physical LED indicator for quick visual correlation. Cross-referencing ntcHWSlotTable with ntcHWSerialNumber and ntcHWProductionDate lets an operator confirm inventory accuracy, and ntcHWRestart provides a remote-recovery action when a faulty unit is detected.

What Can Be Monitored

hardware unit admin/operational state
availability status (fault/degraded)
LED indicator state
serial number and production date
slot occupancy/inventory

OIDs

OID symbolic	OID numeric	Type	Access	Description
ntcHWModule	1.3.6.1.4.1.94.1.16.5.1			The MIB module that is used to control the Hardware Management information.
ntcHWObjs	1.3.6.1.4.1.94.1.16.7.1.1
ntcHWUnitTable	1.3.6.1.4.1.94.1.16.7.1.1.1		not-accessible	A table which contains an entry for each pluggable circuit board (in this MIB a 'unit' is the same as a pluggable circuit board.) Entries of this table are automatically created by the hardware management software.
ntcHWUnitEntry	1.3.6.1.4.1.94.1.16.7.1.1.1.1		not-accessible	A conceptual row in the ntcHWUnitTable. Rows are created automatically by the Hardware Management software.
INT ntcHWAdminState	1.3.6.1.4.1.94.1.16.7.1.1.1.1.1	INTEGER	read-write	Represents the desired state of the unit. inService indicates that the unit is intended to be operating normally. outOfService indicates that the unit should be taken out of normal operating mode and no data traffic should appear in this unit. inTest indicates that the unit should be placed into a selftest mode. missing indicates that the unit is expected to be present but has been detected as not being physically present. The NMS is not allowed to set the value of ntcHWAdminstate to missing.
INT ntcHWOperState	1.3.6.1.4.1.94.1.16.7.1.1.1.1.2	INTEGER	read-only	Indicates the current state of the unit. down indicates that the unit is in a non-functional state. up indicates that the unit is functioning normally.
INT ntcHWAvailabilityStatus	1.3.6.1.4.1.94.1.16.7.1.1.1.1.3	INTEGER	read-only	Provides more specific information on the state of the unit in this conceptual row. The status column has eleven defined values: inCharge = the unit is fully operational and ready to perform its desired tasks; applicationStarting = the application software is starting up; applicationShutdown = the application software is shutting down; platformStarting = Basic platform software is starting up; resetting = the disk files are closed and hardware reset is forced; separated = Only basic OS software is running. The unit can start application software on request; unconfigured = The administrative state of the unit is 'missing', disk files are closed and only basic OS software is running. The unit refuses to start application software; testing = Selftests can be performed, only basic OS are running; standby = The unit is redundant and is fully operational but not in charge of operations. It is ready to move to 'inCharge' state when necessary; dormant = All connections are physically inactive to enable removal of the unit without electric disturbance in the backplane. Only watchdog software is running for a short duration of time; unavailable = The unit is not physically present or cannot be contacted.
INT ntcHWRestart	1.3.6.1.4.1.94.1.16.7.1.1.1.1.4	INTEGER	read-write	Provides the ability to reset or perform a hot restart the unit represented by this conceptual row. reset = the Unit is shutdown in an orderly manner and restarted again via hardware reset; hotRestart = only the software in a unit is restarted, a hardware reset is not initiated; detach = all electrical connections of the unit are forced to an inactive state to enable removal of the unit without electrical disturbance in the backplane.
INT ntcHWLedState	1.3.6.1.4.1.94.1.16.7.1.1.1.1.5	INTEGER	read-only	Indicates the current LED color of the unit represented by this conceptual row.
STR ntcHWSerialNumber	1.3.6.1.4.1.94.1.16.7.1.1.1.1.6	DisplayString	read-only	The units serial number in displayable format.
STR ntcHWProductionDate	1.3.6.1.4.1.94.1.16.7.1.1.1.1.7	DisplayString	read-only	The units production date in displayable format.
TIM ntcHWUnitEntryChanged	1.3.6.1.4.1.94.1.16.7.1.1.1.1.8	TimeStamp	read-only	Represents the value of sysUpTime at the instant that this conceptual row entry has changed.
ntcHWSlotTable	1.3.6.1.4.1.94.1.16.7.1.1.2		not-accessible	Table whose entries represent the expected circuit board type. The entries are created automatically by the hardware management software.
ntcHWSlotEntry	1.3.6.1.4.1.94.1.16.7.1.1.2.1		not-accessible	The logical row describing the expected circiut board type of a slot.
OID ntcHWDesiredUnitType	1.3.6.1.4.1.94.1.16.7.1.1.2.1.2	AutonomousType	read-write	The unit type which is expected to be inserted or present in the current slot. An indication of the vendor-specific hardware type of the HWM entity. Note that this is different from the definition of MIB-II's sysObjectID. An agent should set this object to a enterprise-specific registration identifier value indicating the specific equipment type in detail. If no vendor-specific registration identifier exists for this entity, or the value is unknown by this agent, then the value { 0 0 } is returned.
TIM ntcHWLastChangedTime	1.3.6.1.4.1.94.1.16.7.1.1.3	TimeStamp	read-only	The value of sysUpTime at the time any of these events occur: * any instance in the following object changes value: - hwmUnitEntryChanged This object shall be set to value 0 in startup.
I32 ntcHWLoadInventoryContainer	1.3.6.1.4.1.94.1.16.7.1.1.4	Integer32	read-write	Writing any value to this object will cause the hardware management software to reread its configuration file from disk.
ntcHWEvents	1.3.6.1.4.1.94.1.16.7.1.2.0
ntcHWGroups	1.3.6.1.4.1.94.1.16.8.1.1
ntcHWUnits	1.3.6.1.4.1.94.1.16.8.1.1.1			A collection of objects representing the status of a unit.
ntcHWCompliances	1.3.6.1.4.1.94.1.16.8.1.2
