Description: Juniper Networks MIB for managing MPLS Label Distribution Protocol (LDP) sessions and label bindings on Juniper devices.

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 JUNIPER-MPLS-LDP-MIB?

This Juniper enterprise MIB implements Juniper's version of MPLS Label Distribution Protocol (LDP) session and entity management, paralleling the IETF MPLS-LDP-MIB. It exposes LDP entity configuration and identity data — protocol version, LSR identifier, loop-detection capability, admin/operational status, and last-change timestamps for each LDP entity. Monitoring emphasis is on protocol/software status: jnxMplsLdpEntityOperStatus versus jnxMplsLdpEntityAdminStatus reveals whether an LDP session is actually up (a critical fault indicator for label distribution), and jnxMplsLdpEntityLastChange functions like an uptime/stability indicator by showing how recently a session's state changed. It closely mirrors and depends on the standard MPLS-LDP-MIB (RFC 3815) and related MPLS textual conventions. It is deployed on Juniper MPLS-enabled routers (PE/P routers) in service-provider core and edge networks running LDP for label distribution. Network engineers evaluating or troubleshooting this functionality can download the JUNIPER-MPLS-LDP-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in JUNIPER-MPLS-LDP-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

Juniper MPLS-enabled router (PE/P router running LDP)

Monitoring Examples

Polling jnxMplsLdpEntityTable/jnxMplsLdpEntityEntry per jnxMplsLdpEntityIndex lets an operator compare jnxMplsLdpEntityOperStatus against jnxMplsLdpEntityAdminStatus to detect a session that's administratively enabled but operationally down, indicating a neighbor adjacency or transport problem. jnxMplsLdpEntityLdpId identifies which peer session is affected, and jnxMplsLdpEntityLastChange shows how recently the state flapped, helping correlate instability with other network events. jnxMplsLdpLsrId identifies the local LSR for the routing instance being examined.

What Can Be Monitored

LDP entity admin vs. operational status
LDP session state changes/flaps
LSR identifier and loop-detection capability
label distribution session table per entity

How to Use in IPNetwork Monitor

Example using jnxMplsLdpAttemptedSessions OID:

Select a Juniper MPLS-enabled router (PE/P router running LDP) 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 jnxMplsLdpAttemptedSessions 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 total attempted sessions for this LDP Entity. 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 sharply between polls relative to its normal baseline, since an unexpected spike often reflects a real change in traffic or activity. Click Finish to create the monitor; you can adjust any parameter later.

OIDs

OID symbolic	OID numeric	Type	Access	Description
IP jnxMplsFecAddr	1.3.6.1.4.1.2636.3.36.1.3.7.2.1.5	InetAddress	read-only	If the value of 'jnxMplsFecType' is 'prefix(1)' then the value of this object is the address prefix. If the value of the 'jnxMplsFecAddrLength' is object is zero, then this object should also be zero. If the value of the 'jnxMplsFecType' is 'hostAddress(2)' then this is the host address.
IPt jnxMplsFecAddrFamily	1.3.6.1.4.1.2636.3.36.1.3.7.2.1.4	InetAddressType	read-only	The value of this object is from the Address Family Numbers.
I32 jnxMplsFecAddrLength	1.3.6.1.4.1.2636.3.36.1.3.7.2.1.3	Integer32	read-only	If the value of 'jnxMplsFecType' is 'prefix(1)' then the value of this object is the length in bits of the address prefix represented by 'jnxMplsFecAddr', or if the length is zero then this is a special value which indicates that the prefix matches all addresses. In this case the prefix is also zero (i.e. 'jnxMplsFecAddr' will have the value of zero.)
jnxMplsFecEntry	1.3.6.1.4.1.2636.3.36.1.3.7.2.1		not-accessible	Each row represents a single FEC Element.

U32 jnxMplsFecIndexNext	1.3.6.1.4.1.2636.3.36.1.3.7.1	Unsigned32	read-only	This object contains an appropriate value to be used for jnxMplsFecIndex when creating entries in the jnxMplsFecTable. The value 0 indicates that no unassigned entries are available. To obtain the jnxMplsFecIndex value for a new entry, the manager issues a management protocol retrieval operation to obtain the current value of this object. After each retrieval, the agent should modify the value to the next unassigned index.
jnxMplsFecObjects	1.3.6.1.4.1.2636.3.36.1.3.7

INT jnxMplsFecType	1.3.6.1.4.1.2636.3.36.1.3.7.2.1.2	INTEGER	read-only	The type of the FEC. If the value of this object is 'prefix(1)' then the FEC type described by this row is for address prefixes. If the value of this object is 'hostAddress(2)' then the FEC type described by this row is a host address.
C32 jnxMplsLdpAttemptedSessionsEx	1.3.6.1.4.1.2636.3.36.1.2.4.1.1	Counter32	read-only	A count of the total attempted sessions for 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 jnxMplsLdpEntityDiscontinuityTime.
C32 jnxMplsLdpBadLdpIdentifierErrors	1.3.6.1.4.1.2636.3.36.1.2.4.1.6	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 jnxMplsLdpEntityDiscontinuityTime.
C32 jnxMplsLdpBadMessageLengthErrors	1.3.6.1.4.1.2636.3.36.1.2.4.1.8	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.

jnxMplsLdpCompliances	1.3.6.1.4.1.2636.3.36.3.2
jnxMplsLdpConformance	1.3.6.1.4.1.2636.3.36.3
INT jnxMplsLdpEntityAdminStatus	1.3.6.1.4.1.2636.3.36.1.2.3.1.4	INTEGER	read-only	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 jnxMplsLdpPeerTable). At this point the user is able to change values which are related to this entity. When the admin status is set back to 'up', then this Entity will attempt to establish a new session with the Peer.
TIM jnxMplsLdpEntityDiscontinuityTime	1.3.6.1.4.1.2636.3.36.1.2.3.1.20	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, or Counter64 object contained in the 'jnxMplsLdpEntityStatsTable'. If no such discontinuities have occurred since the last re-initialization of the local management subsystem, then this object contains a zero value.
jnxMplsLdpEntityEntry	1.3.6.1.4.1.2636.3.36.1.2.3.1		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.
I32 jnxMplsLdpEntityHelloHoldTimer	1.3.6.1.4.1.2636.3.36.1.2.3.1.10	Integer32	read-only	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 jnxMplsLdpEntityTargetPeer object. If the value of this object is 0: if the value of the jnxMplsLdpEntityTargetPeer 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 jnxMplsLdpEntityTargetPeer 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 jnxMplsLdpEntityHopCountLimit	1.3.6.1.4.1.2636.3.36.1.2.3.1.15	Integer32	read-only	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 jnxMplsLdpLsrLoopDetectionCapable must be set to either 'hopCount(3)' or 'hopCountAndPathVector(5)' if this object has a value greater than 0 (zero), otherwise it is ignored.
U32 jnxMplsLdpEntityIndex	1.3.6.1.4.1.2636.3.36.1.2.3.1.2	Unsigned32	not-accessible	This index is used as a secondary index to uniquely identify this row. Before creating a row in this table, the 'jnxMplsLdpEntityIndexNext' 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 in 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.
U32 jnxMplsLdpEntityIndexNext	1.3.6.1.4.1.2636.3.36.1.2.2	Unsigned32	read-only	This object contains an appropriate value to be used for jnxMplsLdpEntityIndex when creating entries in the jnxMplsLdpEntityTable. The value 0 indicates that no unassigned entries are available. To obtain the jnxMplsLdpEntityIndex value for a new entry, the manager issues a management protocol retrieval operation to obtain the current value of this object. After each retrieval, the agent should modify the value to the next unassigned index.
I32 jnxMplsLdpEntityInitSesThreshold	1.3.6.1.4.1.2636.3.36.1.2.3.1.11	Integer32	read-only	When attempting to establish a session with a given Peer, the given LDP Entity should send out the SNMP notification, 'jnxMplsLdpInitSesThresholdExceeded', 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 possibily 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. A value of 0 (zero) for this object indicates that the threshold is infinity, thus the SNMP notification will never be generated.
I32 jnxMplsLdpEntityKeepAliveHoldTimer	1.3.6.1.4.1.2636.3.36.1.2.3.1.9	Integer32	read-only	The 16-bit integer value which is the proposed keep alive hold timer for this LDP Entity.
MPL jnxMplsLdpEntityLabelDistMethod	1.3.6.1.4.1.2636.3.36.1.2.3.1.12	MplsLabelDistributionMethod	read-only	For any given LDP session, the method of label distribution must be specified.
MPL jnxMplsLdpEntityLabelRetentionMode	1.3.6.1.4.1.2636.3.36.1.2.3.1.13	MplsRetentionMode	read-only	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 jnxMplsLdpEntityLabelType	1.3.6.1.4.1.2636.3.36.1.2.3.1.19	MplsLdpLabelType	read-only	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 jnxMplsLdpEntityAtmParms Table, which corresponds to this entry. If the value is frameRelayParameters(3) then a row must be created in the jnxMplsLdpEntityFrameRelayParms Table, which corresponds to this entry.
TIM jnxMplsLdpEntityLastChange	1.3.6.1.4.1.2636.3.36.1.2.1	TimeStamp	read-only	The value of sysUpTime at the time of the most recent addition or deletion of an entry to the jnxMplsLdpEntityTable/jnxMplsLdpEntityStatsTable. If no such changes have occurred since the last re-initialization of the local management subsystem, then this object contains a zero value.
OID jnxMplsLdpEntityLdpId	1.3.6.1.4.1.2636.3.36.1.2.3.1.1	MplsLdpIdentifier	not-accessible	The LDP identifier.
U32 jnxMplsLdpEntityMaxPduLength	1.3.6.1.4.1.2636.3.36.1.2.3.1.8	Unsigned32	read-only	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 explicitely 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.
jnxMplsLdpEntityObjects	1.3.6.1.4.1.2636.3.36.1.2
INT jnxMplsLdpEntityOperStatus	1.3.6.1.4.1.2636.3.36.1.2.3.1.5	INTEGER	read-only	The operational status of this LDP Entity.
I32 jnxMplsLdpEntityPathVectorLimit	1.3.6.1.4.1.2636.3.36.1.2.3.1.14	Integer32	read-only	If the value of this object is 0 (zero) then Loop Dection 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, 'jnxMplsLdpLsrLoopDetectionCapable', must be set to either 'pathVector(4)' or 'hopCountAndPathVector(5)', if this object has a value greater than 0 (zero), otherwise it is ignored.
I32 jnxMplsLdpEntityProtocolVersion	1.3.6.1.4.1.2636.3.36.1.2.3.1.3	Integer32	read-only	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 jnxMplsLdpEntityRowStatus	1.3.6.1.4.1.2636.3.36.1.2.3.1.22	RowStatus	read-only	An object that allows entries in this table to be created and deleted using the RowStatus convention.
jnxMplsLdpEntityStatsEntry	1.3.6.1.4.1.2636.3.36.1.2.4.1		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. and the Session remains), then the error is counted in the jnxMplsLdpSesStatsEntry.
jnxMplsLdpEntityStatsTable	1.3.6.1.4.1.2636.3.36.1.2.4		not-accessible	This table is a read-only table which augments the jnxMplsLdpEntityTable. The purpose of this table is to keep statistical information about the LDP Entities on the LSR.
STO jnxMplsLdpEntityStorageType	1.3.6.1.4.1.2636.3.36.1.2.3.1.21	StorageType	read-only	The storage type for this entry.
jnxMplsLdpEntityTable	1.3.6.1.4.1.2636.3.36.1.2.3		not-accessible	This table contains information about the MPLS Label Distribution Protocol Entities which exist on this Label Switching Router (LSR).
T/F jnxMplsLdpEntityTargetPeer	1.3.6.1.4.1.2636.3.36.1.2.3.1.16	TruthValue	read-only	If this LDP entity uses targeted peer then set this to true.

NUM jnxMplsLdpHelloAdjHoldTimeRem	1.3.6.1.4.1.2636.3.36.1.3.5.1.1.2	TimeInterval	read-only	The time remaining for this Hello Adjacency. This interval will change when the 'next' Hello message which corresponds to this Hello Adjacency is received.
U32 jnxMplsLdpHelloAdjIndex	1.3.6.1.4.1.2636.3.36.1.3.5.1.1.1	Unsigned32	not-accessible	An identifier for this specific adjacency.
INT jnxMplsLdpHelloAdjType	1.3.6.1.4.1.2636.3.36.1.3.5.1.1.3	INTEGER	read-only	This adjacency is the result of a 'link' hello if the value of this object is link(1). Otherwise, it is a result of a 'targeted' hello, targeted(2).
NTF jnxMplsLdpInitSesThresholdExceeded	1.3.6.1.4.1.2636.3.36.2.0.1			This notification is generated when the value of the 'jnxMplsLdpEntityInitSesThreshold' object is not zero, and the number of Session Initialization messages exceeds the value of the 'jnxMplsLdpEntityInitSesThreshold' object.
C32 jnxMplsLdpKeepAliveTimerExpErrors	1.3.6.1.4.1.2636.3.36.1.2.4.1.11	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 jnxMplsLdpEntityDiscontinuityTime.
jnxMplsLdpLspEntry	1.3.6.1.4.1.2636.3.36.1.3.6.1		not-accessible	An entry in this table represents information on a single LDP LSP which is represented by a session's index triple (jnxMplsLdpEntityLdpId, jnxMplsLdpEntityIndex, jnxMplsLdpPeerLdpId) AND the index tuple (jnxMplsLdpLspIfIndex, jnxMplsLdpLspLabel). The information contained in a row is read-only.
