What Is SNMP-TARGET-MIB?
SNMP-TARGET-MIB is an IETF standards-track MIB (RFC 3413) that defines objects for remotely configuring the destination addresses and parameters an SNMP entity uses when generating notifications or acting as a proxy forwarder. It exposes configuration data rather than hardware telemetry: a table of target addresses (transport domain, transport address, timeout, retry count, tags) and associated message parameters used by notification-originator and proxy applications. Its role in device monitoring is indirect but important — it determines where trap/inform notifications about hardware faults, software events, or performance thresholds actually get delivered, so misconfiguration here can silently break fault and status monitoring even though the underlying device is healthy. It works alongside SNMP-NOTIFICATION-MIB and SNMPv3's SNMP-TARGET-PARAMS to complete the notification-originator application defined in the SNMPv3 framework (RFC 3411-3418 series). It is present on virtually any SNMPv3-capable device or NMS that needs to configure trap/inform destinations dynamically via SNMP rather than static configuration, and administrators searching for the SNMP Target MIB will find that it works in tandem with SNMP-NOTIFICATION-MIB to fully define where and how notifications get delivered.
IPNetwork Monitor allows you to monitor SNMP objects defined in SNMP-TARGET-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.
What Can Be Monitored
- configured target/NMS addresses
- target timeout and retry count
- target tag list
- target row status (active/disabled)
- target storage type
Supported Devices
- vendor-neutral, standards-based MIB, not tied to a specific manufacturer; applies to any SNMPv3-capable network device or management station
Monitoring Examples
An administrator managing trap delivery would inspect snmpTargetAddrTable/snmpTargetAddrEntry, keyed by snmpTargetAddrName, to confirm snmpTargetAddrTAddress points to the correct NMS IP and that snmpTargetAddrTimeout and snmpTargetAddrRetryCount are set appropriately for a lossy WAN link. If notifications stop arriving at a monitoring station, checking snmpTargetAddrRowStatus and snmpTargetAddrTagList can reveal a disabled or mistagged target entry that silently dropped fault/trap delivery for that device.

| snmpTargetMIB | 1.3.6.1.6.3.12 | This MIB module defines MIB objects which provide mechanisms to remotely configure the parameters used by an SNMP entity for the generation of SNMP messages. Copyright (C) The Internet Society (2002). This version of this MIB module is part of RFC 3413; see the RFC itself for full legal notices. | ||
| snmpTargetObjects | 1.3.6.1.6.3.12.1 | |||
| TES snmpTargetSpinLock | 1.3.6.1.6.3.12.1.1 | TestAndIncr | read-write | This object is used to facilitate modification of table entries in the SNMP-TARGET-MIB module by multiple managers. In particular, it is useful when modifying the value of the snmpTargetAddrTagList object. The procedure for modifying the snmpTargetAddrTagList object is as follows: 1. Retrieve the value of snmpTargetSpinLock and of snmpTargetAddrTagList. 2. Generate a new value for snmpTargetAddrTagList. 3. Set the value of snmpTargetSpinLock to the retrieved value, and the value of snmpTargetAddrTagList to the new value. If the set fails for the snmpTargetSpinLock object, go back to step 1. |
| snmpTargetAddrTable | 1.3.6.1.6.3.12.1.2 | not-accessible | A table of transport addresses to be used in the generation of SNMP messages. | |
| snmpTargetAddrEntry | 1.3.6.1.6.3.12.1.2.1 | not-accessible | A transport address to be used in the generation of SNMP operations. Entries in the snmpTargetAddrTable are created and deleted using the snmpTargetAddrRowStatus object. | |
| STR snmpTargetAddrName | 1.3.6.1.6.3.12.1.2.1.1 | SnmpAdminString | not-accessible | The locally arbitrary, but unique identifier associated with this snmpTargetAddrEntry. |
| TDO snmpTargetAddrTDomain | 1.3.6.1.6.3.12.1.2.1.2 | TDomain | read-create | This object indicates the transport type of the address contained in the snmpTargetAddrTAddress object. |
| ADR snmpTargetAddrTAddress | 1.3.6.1.6.3.12.1.2.1.3 | TAddress | read-create | This object contains a transport address. The format of this address depends on the value of the snmpTargetAddrTDomain object. |
| NUM snmpTargetAddrTimeout | 1.3.6.1.6.3.12.1.2.1.4 | TimeInterval | read-create | This object should reflect the expected maximum round trip time for communicating with the transport address defined by this row. When a message is sent to this address, and a response (if one is expected) is not received within this time period, an implementation may assume that the response will not be delivered. Note that the time interval that an application waits for a response may actually be derived from the value of this object. The method for deriving the actual time interval is implementation dependent. One such method is to derive the expected round trip time based on a particular retransmission algorithm and on the number of timeouts which have occurred. The type of message may also be considered when deriving expected round trip times for retransmissions. For example, if a message is being sent with a securityLevel that indicates both authentication and privacy, the derived value may be increased to compensate for extra processing time spent during authentication and encryption processing. |
| I32 snmpTargetAddrRetryCount | 1.3.6.1.6.3.12.1.2.1.5 | Integer32 | read-create | This object specifies a default number of retries to be attempted when a response is not received for a generated message. An application may provide its own retry count, in which case the value of this object is ignored. |
| SNM snmpTargetAddrTagList | 1.3.6.1.6.3.12.1.2.1.6 | SnmpTagList | read-create | This object contains a list of tag values which are used to select target addresses for a particular operation. |
| STR snmpTargetAddrParams | 1.3.6.1.6.3.12.1.2.1.7 | SnmpAdminString | read-create | The value of this object identifies an entry in the snmpTargetParamsTable. The identified entry contains SNMP parameters to be used when generating messages to be sent to this transport address. |
| STO snmpTargetAddrStorageType | 1.3.6.1.6.3.12.1.2.1.8 | StorageType | read-create | The storage type for this conceptual row. Conceptual rows having the value 'permanent' need not allow write-access to any columnar objects in the row. |
| ROW snmpTargetAddrRowStatus | 1.3.6.1.6.3.12.1.2.1.9 | RowStatus | read-create | The status of this conceptual row. To create a row in this table, a manager must set this object to either createAndGo(4) or createAndWait(5). Until instances of all corresponding columns are appropriately configured, the value of the corresponding instance of the snmpTargetAddrRowStatus column is 'notReady'. In particular, a newly created row cannot be made active until the corresponding instances of snmpTargetAddrTDomain, snmpTargetAddrTAddress, and snmpTargetAddrParams have all been set. The following objects may not be modified while the value of this object is active(1): - snmpTargetAddrTDomain - snmpTargetAddrTAddress An attempt to set these objects while the value of snmpTargetAddrRowStatus is active(1) will result in an inconsistentValue error. |
| snmpTargetParamsTable | 1.3.6.1.6.3.12.1.3 | not-accessible | A table of SNMP target information to be used in the generation of SNMP messages. | |
| snmpTargetParamsEntry | 1.3.6.1.6.3.12.1.3.1 | not-accessible | A set of SNMP target information. Entries in the snmpTargetParamsTable are created and deleted using the snmpTargetParamsRowStatus object. | |
| STR snmpTargetParamsName | 1.3.6.1.6.3.12.1.3.1.1 | SnmpAdminString | not-accessible | The locally arbitrary, but unique identifier associated with this snmpTargetParamsEntry. |
| SNM snmpTargetParamsMPModel | 1.3.6.1.6.3.12.1.3.1.2 | SnmpMessageProcessingModel | read-create | The Message Processing Model to be used when generating SNMP messages using this entry. |
| SNM snmpTargetParamsSecurityModel | 1.3.6.1.6.3.12.1.3.1.3 | SnmpSecurityModel | read-create | The Security Model to be used when generating SNMP messages using this entry. An implementation may choose to return an inconsistentValue error if an attempt is made to set this variable to a value for a security model which the implementation does not support. |
| STR snmpTargetParamsSecurityName | 1.3.6.1.6.3.12.1.3.1.4 | SnmpAdminString | read-create | The securityName which identifies the Principal on whose behalf SNMP messages will be generated using this entry. |
| SNM snmpTargetParamsSecurityLevel | 1.3.6.1.6.3.12.1.3.1.5 | SnmpSecurityLevel | read-create | The Level of Security to be used when generating SNMP messages using this entry. |
| STO snmpTargetParamsStorageType | 1.3.6.1.6.3.12.1.3.1.6 | StorageType | read-create | The storage type for this conceptual row. Conceptual rows having the value 'permanent' need not allow write-access to any columnar objects in the row. |
| ROW snmpTargetParamsRowStatus | 1.3.6.1.6.3.12.1.3.1.7 | RowStatus | read-create | The status of this conceptual row. To create a row in this table, a manager must set this object to either createAndGo(4) or createAndWait(5). Until instances of all corresponding columns are appropriately configured, the value of the corresponding instance of the snmpTargetParamsRowStatus column is 'notReady'. In particular, a newly created row cannot be made active until the corresponding snmpTargetParamsMPModel, snmpTargetParamsSecurityModel, snmpTargetParamsSecurityName, and snmpTargetParamsSecurityLevel have all been set. The following objects may not be modified while the value of this object is active(1): - snmpTargetParamsMPModel - snmpTargetParamsSecurityModel - snmpTargetParamsSecurityName - snmpTargetParamsSecurityLevel An attempt to set these objects while the value of snmpTargetParamsRowStatus is active(1) will result in an inconsistentValue error. |
| C32 snmpUnavailableContexts | 1.3.6.1.6.3.12.1.4 | Counter32 | read-only | The total number of packets received by the SNMP engine which were dropped because the context contained in the message was unavailable. |
| C32 snmpUnknownContexts | 1.3.6.1.6.3.12.1.5 | Counter32 | read-only | The total number of packets received by the SNMP engine which were dropped because the context contained in the message was unknown. |
