Description: Defines Nortel NMI fault and alarm notifications for hardware and software failure events on Nortel 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.

What Is NORTEL-NMI-FAULT-NOTI-MIB?

NORTEL-NMI-FAULT-NOTI-MIB is a Nortel (later Avaya) vendor MIB defining the fault management notifications for the Nortel Network Management Interface (NMI) framework, part of Nortel's networking/telecom equipment line. Its purpose is to expose SNMP trap/notification definitions used to signal hardware and software failure events, rather than polled configuration or performance counters. Because it is a notification-only module, its contribution to device status monitoring is asynchronous fault reporting: it lets a management station learn immediately when a Nortel device experiences a hardware fault, software error, or other significant failure condition, rather than requiring a polling loop. It depends on the broader Nortel NMI object/event framework (typically referencing companion Nortel MIBs that define the affected components) for full context of each notification. It is typically deployed alongside other Nortel/Avaya carrier or enterprise networking equipment where centralized fault-event alarm collection is required. Engineers can download the NORTEL-NMI-FAULT-NOTI-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in NORTEL-NMI-FAULT-NOTI-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 runtime data objects were included in the sample objects for this MIB, so a concrete polling scenario cannot be honestly constructed; in practice a network management station would instead subscribe to this module's trap definitions so that when a monitored Nortel device raises a hardware or software fault, the corresponding notification is forwarded to the NMS for alarm correlation and alerting.

OIDs

OID symbolic	OID numeric	Type	Access	Description
nortelNMIneStateChangeNotificationGroup	1.3.6.1.4.1.562.29.1.2.1.2.3			Nortel NMI NE state change notification group.
nortelNMIneAlarmNotificationsGroup	1.3.6.1.4.1.562.29.1.2.1.2.4			Nortel NMI NE alarm notification group.
nortelNMIfaultNotiMIB	1.3.6.1.4.1.562.29.1.6.4			This module contains the fault management related notifications for the Nortel NMI.
nortelNMIfaultNotiPrefix	1.3.6.1.4.1.562.29.1.6.4.0			This OID represents the prefix branch for all Nortel NMI fault Notifications. The last but one sub identifier in the OID of any Notification must have the value zero to facilitate v2v1 conversion.
NTF nortelNMIneOSIstateChangeNotification	1.3.6.1.4.1.562.29.1.6.4.0.101			This notification indicates that one of the NE OSI states has been changed. The modified value of the specific state would be included as the varbind in the actual Notification PDU. We currently support changes to admin state, operational state and unknown status.
NTF nortelNMIalarmClearNotification	1.3.6.1.4.1.562.29.1.6.4.0.201			This notification indicates that one or more previously reported alarms have been cleared and the previously reported alarms are identified via the correlation id list field. The varbinds include alarm context via the ComponentId field and other additional useful information.
NTF nortelNMIwarningAlarmNotification	1.3.6.1.4.1.562.29.1.6.4.0.202			This notification indicates that an alarm of 'Warning' severity has been raised on a NE. The varbinds include alarm context via the ComponentId field and other additional useful information on the alarm condition.
NTF nortelNMIminorAlarmNotification	1.3.6.1.4.1.562.29.1.6.4.0.203			This notification indicates that an alarm of 'Minor' severity has been raised on a NE. The varbinds include alarm context via the ComponentId field and other additional useful information on the alarm condition.
NTF nortelNMImajorAlarmNotification	1.3.6.1.4.1.562.29.1.6.4.0.204			This notification indicates that an alarm of 'Major' severity has been raised on a NE. The varbinds include alarm context via the ComponentId field and other additional useful information on the alarm condition.
NTF nortelNMIcriticalAlarmNotification	1.3.6.1.4.1.562.29.1.6.4.0.205			This notification indicates that an alarm of 'Critical' severity has been raised on a NE. The varbinds include alarm context via the ComponentId field and other additional useful information on the alarm condition.
nortelNMIfaultNotiVarbinds	1.3.6.1.4.1.562.29.1.6.4.1			This OID represents the branch which contains varbinds to fault management related notifications.
STR nortelNMInotifyAlarmComponentId	1.3.6.1.4.1.562.29.1.6.4.1.1	DisplayString	accessible-for-notify	This variable represents the Distinguished Name (DN) (refer X.720) of the component object against which the particular alarm is raised. The entire component hierarchy should be presented in the category-value information model to unambiguosly identify the specific component object instance. Here category refers to the type of the component and value refers to the instance identifier, both are represented as strings. The format of the string is NEtype=NEname;component class=component instance Id;.... The root component is always the NE and the NE is identified via its type as the category and the value as the NE name. The managed element class for the NE is implicitly assumed. The NE type is based on NortelNMIneType textual convention. With NE as the root, the entire containment with the list of Relative Distinguished Names (RDNs) is presented upto the point where the alarming component is clearly identified. Semicolon is the delimiter between a 'category=value' pair. The string can only contain alphanumeric characters and underscores. No commas, spaces, slashes, hyphens, or dollar signs is allowed.
NOR nortelNMInotifyAlarmCategory	1.3.6.1.4.1.562.29.1.6.4.1.2	NortelNMIalarmProblemCategory	accessible-for-notify	This variable presents the problem category of the alarm as per the definition of the textual convention NortelNMIalarmProblemCategory from NORTEL-NMI-TC-MIB.
U32 nortelNMInotifyAlarmNotificationID	1.3.6.1.4.1.562.29.1.6.4.1.3	Unsigned32	accessible-for-notify	This variable is the notification identifier of the alarm that must be unique across all notifications of the particular NE in context through the time that correlation is significant.
STR nortelNMInotifyAlarmDescription	1.3.6.1.4.1.562.29.1.6.4.1.4	DisplayString	accessible-for-notify	This variable provides the description text for the particular alarm.
NOR nortelNMInotifyAlarmTimeStamp	1.3.6.1.4.1.562.29.1.6.4.1.5	NortelNMItimeStampDef	accessible-for-notify	This variable presents the relative timestamp of occurrence of the alarm. NortelNMItimeStampDef textual convention is defined at the NORTEL-NMI-TC-MIB.
NOR nortelNMInotifyAlarmProbableCause	1.3.6.1.4.1.562.29.1.6.4.1.6	NortelNMIalarmProbableCause	accessible-for-notify	This variable provides the probable cause of the particular alarm.
STR nortelNMInotifyAlarmSpecificProblem	1.3.6.1.4.1.562.29.1.6.4.1.7	DisplayString	accessible-for-notify	This variable provides the specific problem data (ITU-T X.733) to further qualify the probable cause of the particular alarm.
STR nortelNMInotifyAlarmCorrelationIdList	1.3.6.1.4.1.562.29.1.6.4.1.8	DisplayString	accessible-for-notify	This variable provides the list of Notification Ids of previously reported alarms that this alarm correlates to. This correlation refers to implicitly clearing the previously raised alarms and overriding them with this alarm report. The format of this string is 'notificationID1;notificationID2......', with a list of integer notification ID values corresponding to the correlated alarms with ';' as the delimiter between any two Notification Identifiers.
NOR nortelNMInotifyNeStateChangeTime	1.3.6.1.4.1.562.29.1.6.4.1.9	NortelNMItimeStampDef	accessible-for-notify	This variable represents the time at which a certain NE state has been changed.
