What Is DELL-NETWORKING-TRAP-EVENT-MIB?

DELL-NETWORKING-TRAP-EVENT-MIB is a Dell Networking OS MIB that centralizes trap/event history tracking for Dell switch platforms, allowing operators to review previously fired traps via SNMP polling rather than only real-time reception. It defines a history trap event table (dellNetHistoryTrapEventTable/Entry) recording each event's sequence ID, severity, type, message text, source OID, chassis slot, and timestamp, plus a parallel active trap event table for conditions still outstanding, such as a card-down state that persists until a corresponding card-up event clears it. Its monitoring value is squarely in fault/event visibility: administrators can retrospectively audit what alarms occurred, their severity, and which slot/module raised them, and distinguish transient logged events from ongoing active fault conditions. It relies on the chassis's underlying module/slot identification and on the same trap OIDs defined elsewhere in Dell's Networking OS MIB set, complementing rather than replacing those trap-generating MIBs. It's deployed on Dell Networking modular switches/chassis in data centers where engineers need a persistent, pollable audit trail of hardware and system alarms. Engineers can download the DELL-NETWORKING-TRAP-EVENT-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in DELL-NETWORKING-TRAP-EVENT-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 engineer troubleshooting an intermittent card outage would walk dellNetHistoryTrapEventTable, filtering by historyTrapEventType and historyTrapEventSlot to find card-down/card-up pairs for a given slot, checking historyTrapEventTimeStamp for a timeline and historyTrapEventSeverity to prioritize. Checking dellNetActiveTrapEvent reveals whether that slot's fault condition is still outstanding, while dellNetLastTrapEventSeqId indicates the most recent logged event overall. dellNetChassisBootupTime helps correlate whether a burst of events followed a recent chassis reboot.

OIDs

OID symbolic	OID numeric	Type	Access	Description
dellNetTrapEventMib	1.3.6.1.4.1.6027.3.6			Dell Networking OS Trap Alarm MIB. Dell Networking OS Trap Event MIB allows users to track or to view the trap events logged by the system. There are two types of trap event tables, hostory trap event table and active trap event table. All the traps sent by the system are logged to history trap event table. The trap that need action will logged to active trap event table; 'Card down' trap event will go to the active trap event table, and the trap will be cleared as soon as 'Card Up' event is issued.
dellNetTrapEventObjects	1.3.6.1.4.1.6027.3.6.1
dellNetHistoryTrapEvent	1.3.6.1.4.1.6027.3.6.1.1
DAT dellNetChassisBootupTime	1.3.6.1.4.1.6027.3.6.1.1.1	DateAndTime	read-only	The dellNetChassisBootupTime used the timestamp to uniquely identify the system between system reboots. Each time an NMS connects to a chassis, it should verify its dellNetChassisBootupTime. If the time is different, it should refresh its history and active tables. But, if the dellNetChassisBootupTime is the same, then it should query the dellNetLastTrapEventSeqId and update its history and active tables from its own dellNetLastTrapEventSeqId to the chassis dellNetLastTrapEventSeqId.
I32 dellNetLastTrapEventSeqId	1.3.6.1.4.1.6027.3.6.1.1.2	Integer32	read-only	dellNetLastTrapEventSeqId is a sequential ID indicated the number of traps sent by the syatem since chassis is loaded. The same id can also be used as the index to the history and active tables. Anytime, if an NMS dropped its connection with a chassis, it should sync up its history tables from its own dellNetLastTrapEventSeqId to the chassis dellNetLastTrapEventSeqId.
I32 dellNetMaxHistoryTableSize	1.3.6.1.4.1.6027.3.6.1.1.3	Integer32	read-only	dellNetMaxHistoryTableSize is the maximum rows in history table. This also limits the active/varbind tables. Whenever there is a chance of overflow, the oldest entry will be deleted form the history table. Respective entry from active table also will be deleted and the corresponding varbind entries will be deleted from varbind table.
dellNetHistoryTrapEventTable	1.3.6.1.4.1.6027.3.6.1.1.4		not-accessible	A table of history trap event table.

TIK historyTrapEventTimeStamp	1.3.6.1.4.1.6027.3.6.1.1.4.1.7	TimeTicks	read-only	The timestamp when the trap is sent.
I32 historyTrapEventPort	1.3.6.1.4.1.6027.3.6.1.1.4.1.8	Integer32	read-only	Corresponsding to chAlarmVarPort in trap definition. This field may be used for other instance depending on the trap type, for example, tray number in case of fan or power supply trap. The value of -1 is used for non-applicable case.
