What Is Nortel-Magellan-Passport-AlarmMIB?

Nortel-Magellan-Passport-AlarmMIB manages the alarm/fault reporting subsystem of the Nortel Magellan Passport, a legacy Nortel wide-area packet/frame-relay switching platform, defining the alarm log, severity levels, and notification configuration for the device. It exposes per-alarm data such as the originating component's row pointer and name, event time, active-list status, severity, alarm type, probable cause, an NTP (network time) index, free-text comment data, a notification ID, and a hierarchical-clear flag, plus a defined alarm trap and mandatory alarm information object. This module is entirely dedicated to software/hardware fault-status monitoring: it is how an operator sees that a specific component on the Passport switch has raised an alarm, what its severity and probable cause are, and when it occurred, functioning much like a fault/event log for the whole chassis. It relies on Nortel's broader Magellan Passport MIB component-naming conventions (componentName/componentRowPointer) shared across the other Passport MIBs in this family (e.g., the APPN and Bridge MIBs), since alarms reference components defined there. It is deployed on Nortel Magellan Passport WAN switches in carrier or large-enterprise packet-switched networks. Engineers can download the Nortel-Magellan-Passport-AlarmMIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in Nortel-Magellan-Passport-AlarmMIB. 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 operator would monitor alarmTrap notifications and walk the alarm table filtering on severity to find any component with a critical or major alarmType, then use componentName/componentRowPointer and probableCause to identify exactly which module or link is faulted and eventTime to see when it started. An alarm entry with lpForHierClear not yet set alongside a high severity value would reveal an unresolved fault still requiring operator acknowledgment or downstream clearing.

The variables listed in the VARIABLES clause, defined in the `mandatoryAlarmInfo' group are present in all cleared alarms. Additional variables as defined in the 'optionalAlarmInfo' group may be included if appropriate.
NTF indeterminateAlarm	1.3.6.1.4.1.562.2.4.1.3.2.0.6			This trap is used to provide a real time indication of an indeterminate Alarm condition. The variables listed in the VARIABLES clause, defined in the `mandatoryAlarmInfo' group are present in all indeterminate alarms. Additional variables as defined in the 'optionalAlarmInfo' group may be included if appropriate.
mandatoryAlarmInfo	1.3.6.1.4.1.562.2.4.1.3.2.7
NUM componentRowPointer	1.3.6.1.4.1.562.2.4.1.3.2.7.1	RowPointer	not-accessible	A pointer to the RowStatus variable of the component emitting the alarm.
STR componentName	1.3.6.1.4.1.562.2.4.1.3.2.7.2	DisplayString	not-accessible	The textual name of the component emitting the alarm in a format suitable for use in commands entered on the `console'. It includes the name of the node from which the alarm was sent, as specified in `ModuleData nodeName'.
DAT eventTime	1.3.6.1.4.1.562.2.4.1.3.2.7.3	DateAndTime	not-accessible	The date and time at which the alarmed event occurred.
INT activeListStatus	1.3.6.1.4.1.562.2.4.1.3.2.7.4	INTEGER	not-accessible	The active alarm list status. This may be used by the Manager to add (on receiving a set) and delete (on receiving a clear) alarms from the alarm displays.
INT severity	1.3.6.1.4.1.562.2.4.1.3.2.7.5	INTEGER	not-accessible	The severity of the alarm which should indicate what priority that fixing this problem should be given. All values are OSI-defined; refer to CCITT X.733/ISO 10164-4 for a more complete description.
INT alarmType	1.3.6.1.4.1.562.2.4.1.3.2.7.6	INTEGER	not-accessible	The alarm type field as defined by OSI which is used to indicate a broad category of what is wrong. The first 6 values are OSI-defined; refer to CCITT X.733/ISO 10164-4 (for the first 5) and CCITT X.736/ISO 10164-4 (for the last) for a more complete description. The value 'operator' is used when an alarm is issued due to an operator command. The values 'debug' and 'unknown' are for compatibility with older switches and are used for debugging alarms and for those which do not fit any of the above, respectively.
INT probableCause	1.3.6.1.4.1.562.2.4.1.3.2.7.7	INTEGER	not-accessible	The probable cause for the alarm which usually qualifies the Alarm Type field. Most values are OSI-defined; refer refer to CCITT X.733 and X.736 (ISO 10164-4 and 10164-7) for a more complete description.
STR ntpIndex	1.3.6.1.4.1.562.2.4.1.3.2.7.8	DigitString	not-accessible	An 8-digit code which is an index into an NTP to provide more description of the alarm and possible actions to take. The first 4 digits indicate a 'group' of alarms (belonging to a particular subsystem or component, etc.). The last 4 digits are a subindex arbitrarily assigned by the application which is responsible for them.
STR commentData	1.3.6.1.4.1.562.2.4.1.3.2.7.9	AsciiString	not-accessible	Additional textual information for the network operator to use. It contains only ASCII characters. Note: The total number of bytes in commentData, operatorData, and internalData may not exceed 750 bytes.
optionalAlarmInfo	1.3.6.1.4.1.562.2.4.1.3.2.8
HEX notificationID	1.3.6.1.4.1.562.2.4.1.3.2.8.1	Hex	not-accessible	The notification Id of the alarm. The high-order byte is the card number of the card from which this alarm originated. The low-order 24 bits contain a sequence number which increases each time an alarm is generated. Thus, this id provides a simple way of uniquely identifying an alarm as well as the order in which alarms are generated on a card. For cross-card ordering, one would have to look at the time stamp (see dateAndTime).
NUM lpForHierClear	1.3.6.1.4.1.562.2.4.1.3.2.8.2	RowPointer	not-accessible	A pointer to the RowStatus variable of the Logical Processor the component generating the alarm is running on. A component generating an Alarm with `activeListStatus = set' can include this variable in the Alarm. If the identified Logical Processor generates a Hierarchical Clear Alarm, then it will clear the Set Alarm.
STR operatorData	1.3.6.1.4.1.562.2.4.1.3.2.8.3	HexString	not-accessible	Additional hexadecimal information for the network operator to use. Note: The total number of bytes in commentData, operatorData, and internalData may not exceed 750 bytes.
STR pid	1.3.6.1.4.1.562.2.4.1.3.2.8.4	DisplayString	not-accessible	A string representation of the internal process id (Pid) of the process which generated the alarm (for internal use only). Note that it may or may not map to the componentName field.
STR fileName	1.3.6.1.4.1.562.2.4.1.3.2.8.5	DisplayString	not-accessible	An internal filename (for internal use only).
U32 fileLineNumber	1.3.6.1.4.1.562.2.4.1.3.2.8.6	Unsigned32	not-accessible	An internal line number in the file (see filename) referred to above (for internal use only).
STR fileVersion	1.3.6.1.4.1.562.2.4.1.3.2.8.7	DisplayString	not-accessible	A version indicator of the file (filename) referred to above (for internal use only).
STR internalData	1.3.6.1.4.1.562.2.4.1.3.2.8.8	HexString	not-accessible	An additional internal hexadecimal information for internal use only. Note: The total number of bytes in comment, operator, and internal data may not exceed 750 bytes.
provisionalAlarmInfo	1.3.6.1.4.1.562.2.4.1.3.2.9
U32 cid	1.3.6.1.4.1.562.2.4.1.3.2.9.1	Unsigned32	not-accessible	This is a Custom Identifier(CID) of the component which generated the alarm
