Description: Defines alarm notification objects for SNMP 553-series network device fault and threshold events.

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 SNMP553-ALARM-MIB?

SNMP553-ALARM-MIB defines alarm notification objects for a 553-series network device family, providing a generic text-alarm table used to surface fault and threshold events to a management station. It exposes a simple alarm table with a numeric alarm identifier, free-text description, and current status field, functioning as a lightweight fault log accessible via SNMP. Its monitoring purpose is entirely device/software fault status: polling the alarm table reveals what alarm conditions are currently active on the device and their descriptive detail, serving as a catch-all mechanism for conditions not covered by more granular hardware-sensor MIBs. It appears to be a self-contained, minimally-structured MIB with no stated dependency on other standard MIBs, consistent with its bare-bones design. It is deployed on 553-series network devices as a simple, generic alarm-reporting mechanism for operational status. Engineers can download the SNMP553-ALARM-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in SNMP553-ALARM-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.

Supported Devices

553-series network device (vendor/product family using this generic alarm scheme)

Monitoring Examples

An operator would poll snmp553sTextAlarmTable/snmp553sTextAlarmEntry rows to read each alarmNumber alongside its description and status, effectively retrieving a live list of currently active device alarms. A new row appearing with a status indicating an active fault and a description referencing, for example, a power or link condition would prompt immediate investigation. Because the table is minimally structured, an admin would typically poll it on a short interval to catch transient alarms before they clear.

OBJECT-IDENTITY

OIDs

OID symbolic	OID numeric	Type	Access	Description
NTF snmp553sTextAlarmTrap	1.3.6.1.4.1.498.6.3.0.1			The snmp553 alarm trap. This trap is set whenever an alarm status change occurs to report an alarm. The variable bindings contain the description and status for each alarm that changes state. Note that the OBJECT IDENTIFIER of the variable contains the interface, family type, and alarm type of the alarm encoded within. More than one alarm can be sent in the trap, if the network element indicates that more than one has changed at the same time.
snmp553sTextAlarm	1.3.6.1.4.1.498.6.3.9
STR snmp553sTextAlarmMIBversion	1.3.6.1.4.1.498.6.3.9.1	DisplayString	read-only	Identifies the version of the MIB. The format of the version is x.yzT, where 'x' identifies the major revision number, 'y'identifies the minor revision number, 'z' identifies the typographical revision, and T identifies the test revision. Acceptable values for the individual revision components are as follows x: 1 - 9 y: 0 - 9 z: 0 - 9 T: A - Z Upon formal release, no designation for the test revision will be present.
INT snmp553sTextAlarmGlobal	1.3.6.1.4.1.498.6.3.9.2	INTEGER	read-write	This globally enables and disables all text based TRAPs from an agent.
snmp553sTextAlarmTable	1.3.6.1.4.1.498.6.3.9.3		not-accessible	The snmp553AlarmTable contains entries that report the status of alarms. The status of an alarm indicates whether the alarm is currently active or inactive. This information will be determined by the network element depending on the alarm threshold configuration. The structure of the table is such that alarm status is supported on a unit or interface basis, and then on an alarm type basis within the interface. For simplicity sake and to support the reporting of status of all alarms, a unit is treated as an interface in this table.
snmp553sTextAlarmEntry	1.3.6.1.4.1.498.6.3.9.3.1		not-accessible	An entry in the Alarm table.
INT alarmNumber	1.3.6.1.4.1.498.6.3.9.3.1.1	INTEGER	read-only	The index value which uniquely identifies the interface to which this entry is applicable.
STR description	1.3.6.1.4.1.498.6.3.9.3.1.2	DisplayString	read-only	The Description of the alarm generated.
INT status	1.3.6.1.4.1.498.6.3.9.3.1.3	INTEGER	read-only	The current status of the alarm. The value inactive(1) indicates that this alarm is currently inactive. The value active(2) indicates that this alarm is currently active.
