Description: Defines SNMP trap notifications for Dell LAN switch events and status changes.

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 Dell-LAN-TRAP-MIB?

This Dell private MIB defines the common trap/notification structure used by Dell LAN switch event notifications, rather than a table of polled runtime state. It exposes trap metadata fields including severity, source, sequence number, and timestamp that accompany other Dell trap definitions. It is fundamentally a fault/event-reporting mechanism: severity classification lets a management station distinguish minor informational events from critical hardware or software faults, and the sequence number and timestamp let an operator correlate and de-duplicate repeated trap deliveries. It functions as an extension to the standard SNMP notification framework (SNMPv2-MIB/NOTIFICATION-TYPE conventions), supplying shared varbinds for other Dell traps. It is deployed on Dell LAN switches that send event notifications to a central network management station or trap receiver. Engineers can download the Dell-LAN-TRAP-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in Dell-LAN-TRAP-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

Dell network switch (PowerConnect/N-Series family)

Monitoring Examples

Because this MIB primarily defines the varbind objects carried inside traps rather than a polled table, there is no scalar or table an admin polls directly; instead a management station receives traps containing dellTrapSeverity, dellTrapSource, dellTrapSeqNum, and dellTrapTimeStamp. An operator would use dellTrapSeverity to prioritize incoming alerts and dellTrapSeqNum to detect gaps or duplicate deliveries. Repeated high-severity traps from the same dellTrapSource in a short window would flag a recurring device fault needing investigation.

NTF resetRequired	1.3.6.1.4.1.674.10895.530			This trap indicates that in order to perform the last SET request, a reset operation of the router/bridge is required. This may occur for any number of reasons such as if the change affects the routing protocols to be switched from SPF to STP. This trap warns the user to manually reset the switch using either physical or software reset.
NTF endTftp	1.3.6.1.4.1.674.10895.540			This trap indicates that the device finished a TFTP transaction with the management station. The dellTrapInfo field will provide TFTP exit code and name/type of the file being transferred.

NTF ipZhrReqStaticConnNotAccepted	1.3.6.1.4.1.674.10895.630			The requested static connection was not accepted because there is no available IP virtual address to allocate to it.
NTF ipZhrVirtualIpAsSource	1.3.6.1.4.1.674.10895.640			The virtual IP address appeared as a source IP. All the connections using it will be deleted and it will not be further allocated to new connections.
NTF ipZhrNotAllocVirtualIp	1.3.6.1.4.1.674.10895.650			The source IP address sent an ARP specifying a virtual IP which was not allocated for this source. This virtual IP will not be allocated to connections of this specific source IP.
NTF stackMasterFailed	1.3.6.1.4.1.674.10895.660			Indicates that the stack master unit has failed. This trap is generated by the new master when it takes over the stack. The dellTrapSource should be the new master unit #, and the dellTrapInfo should identify the old master unit #.
NTF stackNewMasterElected	1.3.6.1.4.1.674.10895.670			Indicates when a new master has been elected. This is different from a stack failure in that the master has not failed but for some reason a new master has been elected (e.g. the user requested a new master. The trap should be generated by the new master. the dellTrapSource should identify the new master, and the dellTrapInfo should identify the old master.
NTF stackMemberUnitFailed	1.3.6.1.4.1.674.10895.680			Indicates that a member of the stack has failed. This condition is detected by the master unit so the dellTrapSource should indicate the master unit ID and the dellTrapInfo should indicate the member unit that failed.
NTF stackNewMemberUnitAdded	1.3.6.1.4.1.674.10895.690			Indicates that a new member unit has been added to the stack. This trap is generated by the master unit so the dellTrapSource should indicate the master unit ID, and the dellTrapInfo should identify the new unit ID.
NTF stackMemberUnitRemoved	1.3.6.1.4.1.674.10895.700			Indicates that a member unit has been removed from the stack. The dellTrapSource indicates the master unit ID and the dellTrapInfo indicates the unit ID being removed.
NTF stackSplitMasterReport	1.3.6.1.4.1.674.10895.710			Indicates that the stack has split into two distinct stacks which means that each stack may end up with its own master temporarily until the stack is rejoined. This is possibly different from the stackMemberUnitFailed trap, which indicates only a single unit failure. This trap indicates that the master has lost track of part of the stack membership so that the other units may elect their own master. The dellTrapSource should indicate the master unit ID and the dellTrapInfo should identify the units that are split from the main stack.
NTF stackSplitNewMasterReport	1.3.6.1.4.1.674.10895.720			Indicates that the stack has split into two distinct stacks which means that each stack may end up with its own master temporarily until the stack is rejoined. This trap is generated by the new master unit elected in the split sub-stack. The dellTrapSource should identify the new master unit ID, and the dellTrapInfo should identify the old master unit ID before the split occured.
NTF stackRejoined	1.3.6.1.4.1.674.10895.730			Indicates that previously split stack has rejoined. The rejoined stack will elect a master and this trap should be generated by the elected master. The dellTrapSource should indicate the master unit ID and the dellTrapInfo should list the unit IDs of the members.
NTF stackLinkFailed	1.3.6.1.4.1.674.10895.740			Indicates a failure in one of the stacking link. If this stack was connected in a ring, then the failure of a stacking link results in a chain stack instead of a ring. Another failure in the chain topology would result in a split stack. If the stack is connected in a meshed or star topology then multiple link failure may be tolerated. This trap may be generated by any unit within the stack and must indicate the source of the failure. The dellTrapSource should identify one end of the link where the failure is detected. The dellTrapInfo may provide additional information about the failure.
NTF dhcpAllocationFailure	1.3.6.1.4.1.674.10895.750			DHCP failed to allocate an IP address to a requesting host because of memory shortage or inadequate configuration of available IP addresses.

dellAlarmGroup	1.3.6.1.4.1.674.10895.5000.1.1
STR dellTrapInfo	1.3.6.1.4.1.674.10895.5000.1.1.1	DisplayString	read-only	This text string may be used to provide additional information regarding the trap being sent. Any specific formatting information is given in the trap definition.
INT dellTrapSeverity	1.3.6.1.4.1.674.10895.5000.1.1.2	INTEGER	read-only	The severity type of the enterprise-specific trap sent to the Network Management Station by the Dell managed device. The Severity level are defined as follows: Critical - service affecting event. Major - a major error which is not service affecting but does require immediate user attention to prevent further degredation of the system, which may lead to a critical error. For example, if a redundant port failure would be considered a major event whereas the failure of an unprotected port is a critical event. Minor - a minor event which is not service affecting and is unlikely to lead to a major or critical event. The user does not need to take immediate actions but some action is required to clear the event. Info - a notification to the user of some event that does not require any user action. For example, a security notification is useful information but does not require the user to take any specific immediate action. This event is not cleared. Clear - this special trap is sent to clear some previously sent trap. Note that if the sequence number sent with the clear event is 0 then the clear event is used to indicate that all outstanding event of this particular type on a given source (dellTrapSource) has been cleared. If the event sequence number (dellTrapSeqNum) is sent with a non-zero value, then the clear event is sent to clear only the specific trap instance designated by the sequence number in question.
STR dellTrapSource	1.3.6.1.4.1.674.10895.5000.1.1.3	DisplayString	read-only	The trap source is a string identifying the component of the device generating the trap. The source identifies the component associated with the fault. This may for example, identify the unit, slot, port, and possibly logical ports (VLAN, LAG) from which the fault occurs. The format of the source string is: 'TYPE=#:TYPE=#:...' where the TYPE may be one of 'unit' or 'slot' or 'port' or 'VLAN' or 'LAG'. For example: 'unit=3:slot=1:port=2' - indicates the trap comes from port 2 in slot 1 of the switch #3 in the stack. 'unit=2:VLAN=10' - indicates the trap comes from VLAN=10 in unit 2. 'unit=1' - indicates the trap comes from unit 1.
U32 dellTrapSeqNum	1.3.6.1.4.1.674.10895.5000.1.1.4	Unsigned32	read-only	Since SNMP traps are transported using UDP, there is a possibility for the trap to be lost in transit. To allow the NMS the ability to detect this possibility, all traps will include a trap sequence number as part of its variable binding list. The trap sequence number may be reset each time the system reboots and will increment for each trap sent from the device. When a missing trap sequence number is detected the NMS may be able to refresh its state of the switch to determine what event it may have missed.
DAT dellTrapTimeStamp	1.3.6.1.4.1.674.10895.5000.1.1.5	DateAndTime	read-only	The trap header includes the system up time which mark when the trap was generated, but often it is important to know the absolute time when the trap was generated. This time stamp is based on GMT (universal time) time zone. This will allow the timestamps to be correlated consistently across a large network.
