What Is LMS-TRAP-FORWARDING-MIB?

LMS-TRAP-FORWARDING-MIB defines objects for configuring how a LAN Management Solution (LMS)-style network management platform forwards received SNMP notifications on to downstream destinations. It exposes a forwarding configuration table listing destination address, community, and port per forwarding entry, plus rate-limiting parameters such as trap window time, maximum traps per window, and a counter of traps dropped due to rate limiting. It is used to monitor the software-level operational status of the trap-forwarding engine itself: whether forwarding entries are active (via row status), and whether the platform is currently rate-limiting and silently dropping notifications during a trap storm. It builds conceptually on standard SNMP notification/management concepts (akin to the SNMP-NOTIFICATION-MIB) though it is a management-platform-specific extension rather than a device MIB. It is deployed on a network management server that relays incoming traps to secondary NMS platforms, ticketing systems, or SIEM tools. Network engineers evaluating or troubleshooting this functionality can download the LMS-TRAP-FORWARDING-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in LMS-TRAP-FORWARDING-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

numDroppedMaxPerWindowTraps, combined with trapWindowTime and maxTrapsPerWindow, lets an admin detect when the forwarding engine is rate-limiting and silently dropping notifications during a trap storm. Rows of lmsEventFwdTable/lmsEventFwdEntry, exposing destinationNetAddr, destinationCommunity, and destinationPort, are polled to verify that forwarding to a specific downstream management station is correctly configured and active via rowStatus.

What Can Be Monitored

forwarding destination configuration (address/community/port)
trap forwarding row status
trap rate-limit window
max traps per window
dropped traps due to rate limiting

INT eventFwdTableModificationStatus	1.3.6.1.4.1.334.3.2.2.1	INTEGER	read-only	Indicates the combination of possible functions allowed on the lmsEventFwdTable table, subject to overriding SNMP security attributes and the ACCESS clause restrictions on the objects themselves. The values are: unknown - Managers privileges are unknown. no-access - Managers may neither read nor write to this table. read-only - Managers may only read the table, they cannot add or delete conceptual rows and cannot change the value of any variable, even those with ACCESS of 'read-write'. read-modify - Managers may read the table, and change the value of variables whose ACCESS is 'read-write'. read-create - Managers may read the table, change the value of variables whose ACCESS is 'read-write', and create or delete conceptual rows in the table.
INT nextFwdEntryIndex	1.3.6.1.4.1.334.3.2.2.2	INTEGER	read-only	The index that may be used by a manager on a 'set-request' PDU to create a new conceptual row in the lmsEventFwdTable table.
NUM trapWindowTime	1.3.6.1.4.1.334.3.2.2.3	TimeInterval	read-write	A control time window, expresses in 1/100ths of a second, used in conjunction with the maxTrapsPerWindow variable to prevent a 'trap storm' caused by a rapidly recurring error condition .
INT maxTrapsPerWindow	1.3.6.1.4.1.334.3.2.2.4	INTEGER	read-write	The maximum number of traps to be forwarded in the time interval expressed in the trapWindowTime variable. Used to prevent a 'trap storm' caused by a rapidly recurring error condition.
CTR numDroppedMaxPerWindowTraps	1.3.6.1.4.1.334.3.2.2.5	Counter	read-only	The number of traps intended for this destination, which were not forwarded due to the maxTrapsPerWindow count being met or exceeded.
lmsEventFwdTable	1.3.6.1.4.1.334.3.2.2.6		not-accessible	The table holding information to control/administer forwarding of LMS events to SNMP-based management stations or applications.

INT fwdEntryIndex	1.3.6.1.4.1.334.3.2.2.6.1.1	INTEGER	read-only	The integer index into the lmsEventFwdTable table.
INT rowStatus	1.3.6.1.4.1.334.3.2.2.6.1.2	INTEGER	read-write	The status of the conceptual row. These are mapped to the same values as the RowStatus textual conversion in SNMPv2 and carry the same semantics.
IP destinationNetAddr	1.3.6.1.4.1.334.3.2.2.6.1.3	IpAddress	read-write	The network address of the destination entity for trap forwarding.
STR destinationCommunity	1.3.6.1.4.1.334.3.2.2.6.1.4	DisplayString	read-write	The community name to be used when sending traps to the destination entity. This variable is non-defined in SNMPv2 implementions.
INT destinationPort	1.3.6.1.4.1.334.3.2.2.6.1.5	INTEGER	read-write	The UDP port at the 'destinationNetAddr' to which the trap should be sent.
INT forwardingEnabled	1.3.6.1.4.1.334.3.2.2.6.1.6	INTEGER	read-write	Indicates whether forwarding is enabled for this destination at the present time. Used to temporarily suspend forwarding.
STR forwardingFilterName	1.3.6.1.4.1.334.3.2.2.6.1.7	DisplayString	read-write	Undefined at the present time - bge.
INT lastTrapSequenceNumber	1.3.6.1.4.1.334.3.2.2.6.1.8	INTEGER	read-only	The sequence number of the last trap sent to this destination. All traps sent to a given destination are sequenced via a 32-bit, wrapping counter. A manager may use this variable to determine if any traps for this destination have been 'lost'.
TIK lastTrapTime	1.3.6.1.4.1.334.3.2.2.6.1.9	TimeTicks	read-only	The value of sysUpTime as included in the last trap sent to this destination.
CTR numDroppedDisabledTraps	1.3.6.1.4.1.334.3.2.2.6.1.10	Counter	read-only	The number of traps intended for this destination, which were not forwarded due to the variable forwardingEnabled begin set to disabled(2).
lmsTrapData	1.3.6.1.4.1.334.3.2.3
INT lmsEvComponentType	1.3.6.1.4.1.334.3.2.3.1	INTEGER	not-accessible	Identifies the type of LMS component issuing the event.
STR lmsEvComponentDN	1.3.6.1.4.1.334.3.2.3.2	DisplayString	not-accessible	Identifies the most unique (rightmost) portion of the Spyder Distinguished Name of the component issuing the event. The combination of lmsEvComponentType and lmsEvComponentDN MUST uniquely identify the issuing component.

INT lmsEvOID	1.3.6.1.4.1.334.3.2.3.4	INTEGER	not-accessible	Identifies the specific LMS event OID conatined in the LMS event.
CTR numLmsEvSequences	1.3.6.1.4.1.334.3.2.3.5	Counter	not-accessible	A monotonically increasing, wrapping counter indication the sequence number of this event, relative to the destination of the trap. Events that are not forwarded to a destination (destination temporarily disabled, windowTime exceeded) do not cause this sequence number to increase.
INT lmsEvSeverity	1.3.6.1.4.1.334.3.2.3.6	INTEGER	not-accessible	The original severity assigned to the LMS event.
STR lmsEvSupportingText	1.3.6.1.4.1.334.3.2.3.7	DisplayString	not-accessible	Textual information supporting the event data. The meaning of the brief text must be obvious in the context of the trap - for the sake of brevity it need not be a gramatically correct sentence.
