Description: Manages the MPLS Label Distribution Protocol (LDP), used to distribute labels and establish Label Switched Paths (LSPs).
IPNetwork Monitor uses several OIDs from this MIB in network discovery and polling the applicable devices. Start monitoring MPLS-LDP-STD-MIB with a free 30-day trial of IPNetwork Monitor.
What Is MPLS-LDP-STD-MIB?
MPLS-LDP-STD-MIB is the IETF standards-track MIB (RFC 3815) for managing the Label Distribution Protocol (LDP), the control-plane protocol MPLS routers use to exchange label bindings and establish Label Switched Paths (LSPs). It defines objects covering LDP entity/session configuration, LDP peer discovery and session state, and label-binding advertisement/withdrawal behavior between LSRs (Label Switching Routers). Its monitoring value is centered on control-plane protocol health: session establishment/failure state between LDP peers, session uptime, and label-binding activity, which together indicate whether the MPLS forwarding fabric's signaling layer is healthy, rather than reporting on physical hardware sensors. As a foundational MPLS control-plane MIB it is commonly referenced and extended by vendor-specific MPLS MIBs (such as Cadant's or Cisco's MPLS/VPN MIBs) that build LDP neighbor and VPN functionality on top of it. It is typically deployed on any MPLS-capable router or switch from any vendor participating in an MPLS label-switched network, most often in service-provider core/edge infrastructure. Engineers can download the MPLS-LDP-STD-MIB file directly to load it into their MIB browser.
IPNetwork Monitor allows you to monitor SNMP objects defined in MPLS-LDP-STD-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
- vendor-neutral, standards-based MIB, not tied to a specific manufacturer
- any MPLS-capable Label Switching Router (LSR)
Monitoring Examples
No sample objects were provided in the source data for this batch entry, so a grounded polling example cannot be constructed from real object names here; based on the RFC 3815 specification this MIB standardly defines, operators typically poll LDP session and peer tables to confirm session state (operational vs. non-operational) between adjacent LSRs and to detect flapping LDP sessions that would disrupt label-switched path establishment, but the exact object names cannot be confirmed from this source.
What Can Be Monitored
- LDP session state
- LDP peer/neighbor discovery
- label binding advertisement/withdrawal

How to Use in IPNetwork Monitor
Example using mplsLdpEntityStatsSessionAttempts OID:
Select a device implementing MPLS-LDP-STD-MIB as the target host to create a monitor — the SNMP service should be up and running on it. Click New Monitor, then check SNMP Custom on the Favorites tab, click Next, and confirm the host. On the next page, click Select... to open the built-in SNMP MIB Browser and type mplsLdpEntityStatsSessionAttempts into the Find box to locate it in the OID tree, selecting the specific row/instance you want to monitor since this is a table column, then select it and click OK. It reports a count of the Session Initialization messages which were sent or received by this LDP Entity and were NAK'd. On the monitor's Main parameters page you can set the target's SNMP port (default 161), credentials, polling interval, and other settings — see the SNMP Monitor help for details. On the State conditions and Alerting tabs, configure when the monitor should change state and trigger an alert; since this is a Counter32-type OID, Value bounds is the most useful condition here — trigger an alert if the counter increases between polls, since a rising count of errors, failures, or discards often points to a real underlying problem. Click Finish to create the monitor; you can adjust any parameter later.
OIDs
| OID symbolic | OID numeric | Type | Access | Description |
|---|---|---|---|---|
| IP mplsFecAddr | 1.3.6.1.2.1.10.166.4.1.3.8.3.1.5 | InetAddress | read-create | The value of this object is interpreted based on the value of the 'mplsFecAddrType' object. This address is then further interpretted as an being used with the address prefix, or as the host address. This further interpretation is indicated by the 'mplsFecType' object. In other words, the FEC element is populated according to the Prefix FEC Element value encoding, or the Host Address FEC Element encoding. |
| ADR mplsFecAddrPrefixLength | 1.3.6.1.2.1.10.166.4.1.3.8.3.1.3 | InetAddressPrefixLength | read-create | If the value of the 'mplsFecType' is 'hostAddress(2)' then this object is undefined. If the value of 'mplsFecType' is 'prefix(1)' then the value of this object is the length in bits of the address prefix represented by 'mplsFecAddr', or zero. If the value of this object is zero, this indicates that the prefix matches all addresses. In this case the address prefix MUST also be zero (i.e., 'mplsFecAddr' should have the value of zero.) |
| IPt mplsFecAddrType | 1.3.6.1.2.1.10.166.4.1.3.8.3.1.4 | InetAddressType | read-create | The value of this object is the type of the Internet address. The value of this object, decides how the value of the mplsFecAddr object is interpreted. |
| mplsFecEntry | 1.3.6.1.2.1.10.166.4.1.3.8.3.1 | not-accessible | Each row represents a single FEC Element. | |
| NUM mplsFecIndex | 1.3.6.1.2.1.10.166.4.1.3.8.3.1.1 | IndexInteger | not-accessible | The index which uniquely identifies this entry. |
| NUM mplsFecIndexNext | 1.3.6.1.2.1.10.166.4.1.3.8.2 | IndexIntegerNextFree | read-only | This object contains an appropriate value to be used for mplsFecIndex when creating entries in the mplsFecTable. The value 0 indicates that no unassigned entries are available. |
| TIM mplsFecLastChange | 1.3.6.1.2.1.10.166.4.1.3.8.1 | TimeStamp | read-only | The value of sysUpTime at the time of the most recent addition/deletion of an entry to/from the mplsLdpFectTable or the most recent change in values to any objects in the mplsLdpFecTable. If no such changes have occurred since the last re-initialization of the local management subsystem, then this object contains a zero value. |
| mplsFecObjects | 1.3.6.1.2.1.10.166.4.1.3.8 | |||
| ROW mplsFecRowStatus | 1.3.6.1.2.1.10.166.4.1.3.8.3.1.7 | RowStatus | read-create | The status of this conceptual row. If the value of this object is 'active(1)', then none of the writable objects of this entry can be modified, except to set this object to 'destroy(6)'. NOTE: if this row is being referenced by any entry in the mplsLdpLspFecTable, then a request to destroy this row, will result in an inconsistentValue error. |
| STO mplsFecStorageType | 1.3.6.1.2.1.10.166.4.1.3.8.3.1.6 | StorageType | read-create | The storage type for this conceptual row. Conceptual rows having the value 'permanent(4)' need not allow write-access to any columnar objects in the row. |
| mplsFecTable | 1.3.6.1.2.1.10.166.4.1.3.8.3 | not-accessible | This table represents the FEC (Forwarding Equivalence Class) Information associated with an LSP. | |
| INT mplsFecType | 1.3.6.1.2.1.10.166.4.1.3.8.3.1.2 | INTEGER | read-create | The type of the FEC. If the value of this object is 'prefix(1)' then the FEC type described by this row is an address prefix. If the value of this object is 'hostAddress(2)' then the FEC type described by this row is a host address. |
| mplsInSegmentLdpLspEntry | 1.3.6.1.2.1.10.166.4.1.3.6.1 | not-accessible | An entry in this table represents information on a single LDP LSP which is represented by a session's index triple (mplsLdpEntityLdpId, mplsLdpEntityIndex, mplsLdpPeerLdpId) AND the index for the mplsInSegmentTable (mplsInSegmentLdpLspLabelIndex) from the MPLS-LSR-STD-MIB. The information contained in a row is read-only. | |
| MPL mplsInSegmentLdpLspIndex | 1.3.6.1.2.1.10.166.4.1.3.6.1.1 | MplsIndexType | not-accessible | This contains the same value as the mplsInSegmentIndex in the MPLS-LSR-STD-MIB's mplsInSegmentTable. |
| MPL mplsInSegmentLdpLspLabelType | 1.3.6.1.2.1.10.166.4.1.3.6.1.2 | MplsLdpLabelType | read-only | The Layer 2 Label Type. |
| mplsInSegmentLdpLspTable | 1.3.6.1.2.1.10.166.4.1.3.6 | not-accessible | A table of LDP LSP's which map to the mplsInSegmentTable in the MPLS-LSR-STD-MIB module. | |
| MPL mplsInSegmentLdpLspType | 1.3.6.1.2.1.10.166.4.1.3.6.1.3 | MplsLspType | read-only | The type of LSP connection. |
| mplsLdpCompliances | 1.3.6.1.2.1.10.166.4.2.2 | |||
| mplsLdpConformance | 1.3.6.1.2.1.10.166.4.2 | |||
| INT mplsLdpEntityAdminStatus | 1.3.6.1.2.1.10.166.4.1.2.3.1.4 | INTEGER | read-create | The administrative status of this LDP Entity. If this object is changed from 'enable' to 'disable' and this entity has already attempted to establish contact with a Peer, then all contact with that Peer is lost and all information from that Peer needs to be removed from the MIB. (This implies that the network management subsystem should clean up any related entry in the mplsLdpPeerTable. This further implies that a 'tear-down' for that session is issued and the session and all information related to that session cease to exist). At this point the operator is able to change values which are related to this entity. When the admin status is set back to 'enable', then this Entity will attempt to establish a new session with the Peer. |
| TIM mplsLdpEntityDiscontinuityTime | 1.3.6.1.2.1.10.166.4.1.2.3.1.21 | TimeStamp | read-only | The value of sysUpTime on the most recent occasion at which any one or more of this entity's counters suffered a discontinuity. The relevant counters are the specific instances associated with this entity of any Counter32 object contained in the 'mplsLdpEntityStatsTable'. If no such discontinuities have occurred since the last re-initialization of the local management subsystem, then this object contains a zero value. |
| mplsLdpEntityEntry | 1.3.6.1.2.1.10.166.4.1.2.3.1 | not-accessible | An entry in this table represents an LDP entity. An entry can be created by a network administrator or by an SNMP agent as instructed by LDP. | |
| U32 mplsLdpEntityHelloHoldTimer | 1.3.6.1.2.1.10.166.4.1.2.3.1.10 | Unsigned32 | read-create | The 16-bit integer value which is the proposed Hello hold timer for this LDP Entity. The Hello Hold time in seconds. An LSR maintains a record of Hellos received from potential peers. This object represents the Hold Time in the Common Hello Parameters TLV of the Hello Message. A value of 0 is a default value and should be interpretted in conjunction with the mplsLdpEntityTargetPeer object. If the value of this object is 0: if the value of the mplsLdpEntityTargetPeer object is false(2), then this specifies that the Hold Time's actual default value is 15 seconds (i.e., the default Hold time for Link Hellos is 15 seconds). Otherwise if the value of the mplsLdpEntityTargetPeer object is true(1), then this specifies that the Hold Time's actual default value is 45 seconds (i.e., the default Hold time for Targeted Hellos is 45 seconds). A value of 65535 means infinite (i.e., wait forever). All other values represent the amount of time in seconds to wait for a Hello Message. Setting the hold time to a value smaller than 15 is not recommended, although not forbidden according to RFC3036. |
| I32 mplsLdpEntityHopCountLimit | 1.3.6.1.2.1.10.166.4.1.2.3.1.15 | Integer32 | read-create | If the value of this object is 0 (zero), then Loop Detection using Hop Counters is disabled. If the value of this object is greater than 0 (zero) then Loop Detection using Hop Counters is enabled, and this object specifies this Entity's maximum allowable value for the Hop Count. Also, the value of the object mplsLdpLsrLoopDetectionCapable must be set to either 'hopCount(3)' or 'hopCountAndPathVector(5)' if this object has a value greater than 0 (zero), otherwise it is ignored. |
| NUM mplsLdpEntityIndex | 1.3.6.1.2.1.10.166.4.1.2.3.1.2 | IndexInteger | not-accessible | This index is used as a secondary index to uniquely identify this row. Before creating a row in this table, the 'mplsLdpEntityIndexNext' object should be retrieved. That value should be used for the value of this index when creating a row in this table. NOTE: if a value of zero (0) is retrieved, that indicates that no rows can be created in this table at this time. A secondary index (this object) is meaningful to some but not all, LDP implementations. For example an LDP implementation which uses PPP would use this index to differentiate PPP sub-links. Another way to use this index is to give this the value of ifIndex. However, this is dependant on the implementation. |
| NUM mplsLdpEntityIndexNext | 1.3.6.1.2.1.10.166.4.1.2.2 | IndexIntegerNextFree | read-only | This object contains an appropriate value to be used for mplsLdpEntityIndex when creating entries in the mplsLdpEntityTable. The value 0 indicates that no unassigned entries are available. |
| I32 mplsLdpEntityInitSessionThreshold | 1.3.6.1.2.1.10.166.4.1.2.3.1.11 | Integer32 | read-create | When attempting to establish a session with a given Peer, the given LDP Entity should send out the SNMP notification, 'mplsLdpInitSessionThresholdExceeded', when the number of Session Initialization messages sent exceeds this threshold. The notification is used to notify an operator when this Entity and its Peer are possibly engaged in an endless sequence of messages as each NAKs the other's Initialization messages with Error Notification messages. Setting this threshold which triggers the notification is one way to notify the operator. The notification should be generated each time this threshold is exceeded and for every subsequent Initialization message which is NAK'd with an Error Notification message after this threshold is exceeded. A value of 0 (zero) for this object indicates that the threshold is infinity, thus the SNMP notification will never be generated. |
| U32 mplsLdpEntityKeepAliveHoldTimer | 1.3.6.1.2.1.10.166.4.1.2.3.1.9 | Unsigned32 | read-create | The 16-bit integer value which is the proposed keep alive hold timer for this LDP Entity. |
| MPL mplsLdpEntityLabelDistMethod | 1.3.6.1.2.1.10.166.4.1.2.3.1.12 | MplsLabelDistributionMethod | read-create | For any given LDP session, the method of label distribution must be specified. |
| MPL mplsLdpEntityLabelRetentionMode | 1.3.6.1.2.1.10.166.4.1.2.3.1.13 | MplsRetentionMode | read-create | The LDP Entity can be configured to use either conservative or liberal label retention mode. If the value of this object is conservative(1) then advertized label mappings are retained only if they will be used to forward packets, i.e., if label came from a valid next hop. If the value of this object is liberal(2) then all advertized label mappings are retained whether they are from a valid next hop or not. |
| MPL mplsLdpEntityLabelType | 1.3.6.1.2.1.10.166.4.1.2.3.1.20 | MplsLdpLabelType | read-create | Specifies the optional parameters for the LDP Initialization Message. If the value is generic(1) then no optional parameters will be sent in the LDP Initialization message associated with this Entity. If the value is atmParameters(2) then a row must be created in the mplsLdpEntityAtmTable, which corresponds to this entry. If the value is frameRelayParameters(3) then a row must be created in the mplsLdpEntityFrameRelayTable, which corresponds to this entry. |
| TIM mplsLdpEntityLastChange | 1.3.6.1.2.1.10.166.4.1.2.1 | TimeStamp | read-only | The value of sysUpTime at the time of the most recent addition or deletion of an entry to/from the mplsLdpEntityTable/mplsLdpEntityStatsTable, or the most recent change in value of any objects in the mplsLdpEntityTable. If no such changes have occurred since the last re-initialization of the local management subsystem, then this object contains a zero value. |
| OID mplsLdpEntityLdpId | 1.3.6.1.2.1.10.166.4.1.2.3.1.1 | MplsLdpIdentifier | not-accessible | The LDP identifier. |
| U32 mplsLdpEntityMaxPduLength | 1.3.6.1.2.1.10.166.4.1.2.3.1.8 | Unsigned32 | read-create | The maximum PDU Length that is sent in the Common Session Parameters of an Initialization Message. According to the LDP Specification [RFC3036] a value of 255 or less specifies the default maximum length of 4096 octets, this is why the value of this object starts at 256. The operator should explicitly choose the default value (i.e., 4096), or some other value. The receiving LSR MUST calculate the maximum PDU length for the session by using the smaller of its and its peer's proposals for Max PDU Length. |
| mplsLdpEntityObjects | 1.3.6.1.2.1.10.166.4.1.2 | |||
| INT mplsLdpEntityOperStatus | 1.3.6.1.2.1.10.166.4.1.2.3.1.5 | INTEGER | read-only | The operational status of this LDP Entity. The value of unknown(1) indicates that the operational status cannot be determined at this time. The value of unknown should be a transient condition before changing to enabled(2) or disabled(3). |
| I32 mplsLdpEntityPathVectorLimit | 1.3.6.1.2.1.10.166.4.1.2.3.1.14 | Integer32 | read-create | If the value of this object is 0 (zero) then Loop Detection for Path Vectors is disabled. Otherwise, if this object has a value greater than zero, then Loop Dection for Path Vectors is enabled, and the Path Vector Limit is this value. Also, the value of the object, 'mplsLdpLsrLoopDetectionCapable', must be set to either 'pathVector(4)' or 'hopCountAndPathVector(5)', if this object has a value greater than 0 (zero), otherwise it is ignored. |
| U32 mplsLdpEntityProtocolVersion | 1.3.6.1.2.1.10.166.4.1.2.3.1.3 | Unsigned32 | read-create | The version number of the LDP protocol which will be used in the session initialization message. Section 3.5.3 in the LDP Specification specifies that the version of the LDP protocol is negotiated during session establishment. The value of this object represents the value that is sent in the initialization message. |
| ROW mplsLdpEntityRowStatus | 1.3.6.1.2.1.10.166.4.1.2.3.1.23 | RowStatus | read-create | The status of this conceptual row. All writable objects in this row may be modified at any time, however, as described in detail in the section entitled, 'Changing Values After Session Establishment', and again described in the DESCRIPTION clause of the mplsLdpEntityAdminStatus object, if a session has been initiated with a Peer, changing objects in this table will wreak havoc with the session and interrupt traffic. To repeat again: the recommended procedure is to set the mplsLdpEntityAdminStatus to down, thereby explicitly causing a session to be torn down. Then, change objects in this entry, then set the mplsLdpEntityAdminStatus to enable, which enables a new session to be initiated. |
| C32 mplsLdpEntityStatsBadLdpIdentifierErrors | 1.3.6.1.2.1.10.166.4.1.2.4.1.6 | Counter32 | read-only | This object counts the number of Bad LDP Identifier Fatal Errors detected by the session(s) (past and present) associated with this LDP Entity. Discontinuities in the value of this counter can occur at re-initialization of the management system, and at other times as indicated by the value of mplsLdpEntityDiscontinuityTime. |
| C32 mplsLdpEntityStatsBadMessageLengthErrors | 1.3.6.1.2.1.10.166.4.1.2.4.1.8 | Counter32 | read-only | This object counts the number of Bad Message Length Fatal Errors detected by the session(s) (past and present) associated with this LDP Entity. Discontinuities in the value of this counter can occur at re-initialization of the management system, and at other times as indicated by the value of mplsLdpEntityDiscontinuityTime. |
| C32 mplsLdpEntityStatsBadPduLengthErrors | 1.3.6.1.2.1.10.166.4.1.2.4.1.7 | Counter32 | read-only | This object counts the number of Bad PDU Length Fatal Errors detected by the session(s) (past and present) associated with this LDP Entity. Discontinuities in the value of this counter can occur at re-initialization of the management system, and at other times as indicated by the value of mplsLdpEntityDiscontinuityTime. |
| C32 mplsLdpEntityStatsBadTlvLengthErrors | 1.3.6.1.2.1.10.166.4.1.2.4.1.9 | Counter32 | read-only | This object counts the number of Bad TLV Length Fatal Errors detected by the session(s) (past and present) associated with this LDP Entity. Discontinuities in the value of this counter can occur at re-initialization of the management system, and at other times as indicated by the value of mplsLdpEntityDiscontinuityTime. |
| mplsLdpEntityStatsEntry | 1.3.6.1.2.1.10.166.4.1.2.4.1 | not-accessible | A row in this table contains statistical information about an LDP Entity. Some counters contained in a row are for fatal errors received during a former LDP Session associated with this entry. For example, an LDP PDU received on a TCP connection during an LDP Session contains a fatal error. That error is counted here, because the session is terminated. If the error is NOT fatal (i.e., the Session remains), then the error is counted in the mplsLdpSessionStatsEntry. | |
| C32 mplsLdpEntityStatsKeepAliveTimerExpErrors | 1.3.6.1.2.1.10.166.4.1.2.4.1.11 | Counter32 | read-only | This object counts the number of Session Keep Alive Timer Expired Errors detected by the session(s) (past and present) associated with this LDP Entity. Discontinuities in the value of this counter can occur at re-initialization of the management system, and at other times as indicated by the value of mplsLdpEntityDiscontinuityTime. |
| C32 mplsLdpEntityStatsMalformedTlvValueErrors | 1.3.6.1.2.1.10.166.4.1.2.4.1.10 | Counter32 | read-only | This object counts the number of Malformed TLV Value Fatal Errors detected by the session(s) (past and present) associated with this LDP Entity. Discontinuities in the value of this counter can occur at re-initialization of the management system, and at other times as indicated by the value of mplsLdpEntityDiscontinuityTime. |
| C32 mplsLdpEntityStatsSessionAttemptsEx | 1.3.6.1.2.1.10.166.4.1.2.4.1.1 | Counter32 | read-only | A count of the Session Initialization messages which were sent or received by this LDP Entity and were NAK'd. In other words, this counter counts the number of session initializations that failed. Discontinuities in the value of this counter can occur at re-initialization of the management system, and at other times as indicated by the value of mplsLdpEntityDiscontinuityTime. |
| C32 mplsLdpEntityStatsSessionRejectedAdErrors | 1.3.6.1.2.1.10.166.4.1.2.4.1.3 | Counter32 | read-only | A count of the Session Rejected/Parameters Advertisement Mode Error Notification Messages sent or received by this LDP Entity. Discontinuities in the value of this counter can occur at re-initialization of the management system, and at other times as indicated by the value of mplsLdpEntityDiscontinuityTime. |
| C32 mplsLdpEntityStatsSessionRejectedLRErrors | 1.3.6.1.2.1.10.166.4.1.2.4.1.5 | Counter32 | read-only | A count of the Session Rejected/Parameters Label Range Notification Messages sent or received by this LDP Entity. Discontinuities in the value of this counter can occur at re-initialization of the management system, and at other times as indicated by the value of mplsLdpEntityDiscontinuityTime. |
| C32 mplsLdpEntityStatsSessionRejectedMaxPduErrors | 1.3.6.1.2.1.10.166.4.1.2.4.1.4 | Counter32 | read-only | A count of the Session Rejected/Parameters Max Pdu Length Error Notification Messages sent or received by this LDP Entity. Discontinuities in the value of this counter can occur at re-initialization of the management system, and at other times as indicated by the value of mplsLdpEntityDiscontinuityTime. |
| C32 mplsLdpEntityStatsSessionRejectedNoHelloErrors | 1.3.6.1.2.1.10.166.4.1.2.4.1.2 | Counter32 | read-only | A count of the Session Rejected/No Hello Error Notification Messages sent or received by this LDP Entity. Discontinuities in the value of this counter can occur at re-initialization of the management system, and at other times as indicated by the value of mplsLdpEntityDiscontinuityTime. |
| C32 mplsLdpEntityStatsShutdownReceivedNotifications | 1.3.6.1.2.1.10.166.4.1.2.4.1.12 | Counter32 | read-only | This object counts the number of Shutdown Notifications received related to session(s) (past and present) associated with this LDP Entity.

| C32 mplsLdpEntityStatsShutdownSentNotifications | 1.3.6.1.2.1.10.166.4.1.2.4.1.13 | Counter32 | read-only | This object counts the number of Shutdown Notfications sent related to session(s) (past and present) associated with this LDP Entity. Discontinuities in the value of this counter can occur at re-initialization of the management system, and at other times as indicated by the value of mplsLdpEntityDiscontinuityTime. |
| mplsLdpEntityStatsTable | 1.3.6.1.2.1.10.166.4.1.2.4 | not-accessible | This table is a read-only table which augments the mplsLdpEntityTable. The purpose of this table is to keep statistical information about the LDP Entities on the LSR. | |
| STO mplsLdpEntityStorageType | 1.3.6.1.2.1.10.166.4.1.2.3.1.22 | StorageType | read-create | The storage type for this conceptual row. Conceptual rows having the value 'permanent(4)' need not allow write-access to any columnar objects in the row. |
| mplsLdpEntityTable | 1.3.6.1.2.1.10.166.4.1.2.3 | not-accessible | This table contains information about the MPLS Label Distribution Protocol Entities which exist on this Label Switching Router (LSR) or Label Edge Router (LER). | |
