Description: Manages BATM Advanced Communication MPLS Label Distribution Protocol (LDP) session configuration, bindings, and neighbor state.

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 PRVT-MPLS-LDP-MIB?

PRVT-MPLS-LDP-MIB is a proprietary enterprise MIB, structured closely on the IETF MPLS-LDP-STD-MIB, used by BATM Advanced Communications equipment to manage the Multiprotocol Label Switching Label Distribution Protocol, covering LSR identity, LDP entity configuration, and session/neighbor state. It defines LSR-level configuration (loop detection capability), per-entity LDP configuration (protocol version, admin status), operational status objects, and notification definitions for LDP events. It directly supports software status monitoring of the MPLS control plane: comparing adminStatus to operStatus on each LDP entity reveals whether a configured LDP session is actually established, and notifications flag session/neighbor state changes such as an LDP peer going down unexpectedly. It closely mirrors the IETF MPLS-LDP-STD-MIB (RFC 3815), so it depends conceptually on that standard and typically coexists with other MPLS MIBs such as MPLS-LSR-MIB and MPLS-TE-MIB. It is deployed on BATM Advanced Communications MPLS-capable routers/switches in carrier or metro networks running LDP-signaled label-switched paths. Engineers can download the PRVT-MPLS-LDP-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in PRVT-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

BATM Advanced Communications MPLS router/switch

Monitoring Examples

An admin polls mplsLdpEntityTable/mplsLdpEntityEntry fields such as mplsLdpEntityAdminStatus and mplsLdpEntityOperStatus to confirm an LDP session is administratively enabled and operationally up. mplsLdpLsrId and mplsLdpLsrLoopDetectionCapable on mplsLdpLsrTable verify the router's LSR identity and loop-detection support. A mismatch between admin and oper status on an entity would flag a failed or down LDP neighbor relationship.

What Can Be Monitored

LDP entity admin/operational status
LSR identifier

How to Use in IPNetwork Monitor

Example using mplsLdpEntityStatsSessionAttempts OID:

Select a BATM Advanced Communications MPLS router/switch (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 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
mplsLdpStdMIB	1.3.6.1.4.1.738.1.6.5.1			This MIB contains managed object definitions for the 'Multiprotocol Label Switching, Label Distribution Protocol, LDP'.
mplsLdpObjects	1.3.6.1.4.1.738.1.6.5.1.1
mplsLdpLsrObjects	1.3.6.1.4.1.738.1.6.5.1.1.1
mplsLdpLsrTable	1.3.6.1.4.1.738.1.6.5.1.1.1.1		not-accessible	This table contains information about the Label Switching Router (LSR) or Label Edge Router (LER) that is running the MPLS Label Distribution Protocol.
mplsLdpLsrEntry	1.3.6.1.4.1.738.1.6.5.1.1.1.1.1		not-accessible	An entry in this table contains the LSR objects specific to an instance of PRVT-CR-LDP.
OID mplsLdpLsrId	1.3.6.1.4.1.738.1.6.5.1.1.1.1.1.1	MplsLsrIdentifier	read-only	The Label Switching Router's Identifier.
INT mplsLdpLsrLoopDetectionCapable	1.3.6.1.4.1.738.1.6.5.1.1.1.1.1.2	INTEGER	read-only	A indication of whether this Label Switching Router supports loop detection. none(1) -- Loop Detection is not supported on this LSR. other(2) -- Loop Detection is supported but by a method other than those listed below. hopCount(3) -- Loop Detection is supported by Hop Count only. pathVector(4) -- Loop Detection is supported by Path Vector only. hopCountAndPathVector(5) -- Loop Detection is supported by both Hop Count And Path Vector. Since Loop Detection is determined during Session Initialization, an individual session may not be running with loop detection. This object simply gives an indication of whether or not the LSR has the ability to support Loop Detection and which types.
mplsLdpEntityObjects	1.3.6.1.4.1.738.1.6.5.1.1.2
mplsLdpEntityTable	1.3.6.1.4.1.738.1.6.5.1.1.2.1		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).
mplsLdpEntityEntry	1.3.6.1.4.1.738.1.6.5.1.1.2.1.1		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.
OID mplsLdpEntityLdpId	1.3.6.1.4.1.738.1.6.5.1.1.2.1.1.1	MplsLdpIdentifier	not-accessible	The LDP identifier. The first four octets encode an IP address assigned to the LSR, and the last two octets identify a specific label space within the LSR.
U32 mplsLdpEntityIndex	1.3.6.1.4.1.738.1.6.5.1.1.2.1.1.2	Unsigned32	not-accessible	This index is used as a secondary index to uniquely identify this row. Before creating a row in this table, the '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. This field is deprecated in the following tables provided by PRVT-CR-LDP Session Controller. - mplsLdpEntityTable. - mplsLdpPeerTable. In these tables the value of the Entity Index will always be filled in to be 1.
I32 mplsLdpEntityProtocolVersion	1.3.6.1.4.1.738.1.6.5.1.1.2.1.1.3	Integer32	read-create	The version number of the protocol. The value of 0 on a read indicates that the version of the protocol is unknown. Otherwise, the value of this object represents the version of the LDP protocol. 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.
INT mplsLdpEntityAdminStatus	1.3.6.1.4.1.738.1.6.5.1.1.2.1.1.4	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 (which implies that the 'mplsLdpEntityRowStatus' object has been set to 'active'), 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 user 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.
INT mplsLdpEntityOperStatus	1.3.6.1.4.1.738.1.6.5.1.1.2.1.1.5	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).
INE mplsLdpEntityWellKnownTcpDiscoveryPort	1.3.6.1.4.1.738.1.6.5.1.1.2.1.1.6	InetPortNumber	read-create	The TCP Port for LDP. The default value is the well-known value of this port.
INE mplsLdpEntityWellKnownUdpDiscoveryPort	1.3.6.1.4.1.738.1.6.5.1.1.2.1.1.7	InetPortNumber	read-create	The UDP Discovery Port for LDP. The default value is the well-known value for this port.
U32 mplsLdpEntityMaxPduLength	1.3.6.1.4.1.738.1.6.5.1.1.2.1.1.8	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 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.
U32 mplsLdpEntityKeepAliveHoldTimer	1.3.6.1.4.1.738.1.6.5.1.1.2.1.1.9	Unsigned32	read-create	The 16-bit integer value which is the proposed keep alive hold timer for this LDP Entity.
U32 mplsLdpEntityHelloHoldTimer	1.3.6.1.4.1.738.1.6.5.1.1.2.1.1.10	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. For auto-created entities that use the global label space (and therefore might correspond to more than one adjacency over more than one interface), this value will only be meaningful if all interfaces that correspond to this entity are configured to use the same hello hold time, since this property can be configured on a per interface basis. If the interfaces have differing configurations, the value returned on a MIB Get will be 0.
I32 mplsLdpEntityInitSessionThreshold	1.3.6.1.4.1.738.1.6.5.1.1.2.1.1.11	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.
MPL mplsLdpEntityLabelDistMethod	1.3.6.1.4.1.738.1.6.5.1.1.2.1.1.12	MplsLabelDistributionMethod	read-create	For any given LDP session, the method of label distribution must be specified.
MPL mplsLdpEntityLabelRetentionMode	1.3.6.1.4.1.738.1.6.5.1.1.2.1.1.13	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.
I32 mplsLdpEntityPathVectorLimit	1.3.6.1.4.1.738.1.6.5.1.1.2.1.1.14	Integer32	read-only	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.
I32 mplsLdpEntityHopCountLimit	1.3.6.1.4.1.738.1.6.5.1.1.2.1.1.15	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 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.
INT mplsLdpEntityTransportAddrKind	1.3.6.1.4.1.738.1.6.5.1.1.2.1.1.16	INTEGER	read-create	This specifies whether the loopback or interface address is to be used as the transport address in the transport address TLV of the hello message. If the value is interface(1), then the IP address of the interface from which hello messages are sent is used as the transport address in the hello message. Otherwise, if the value is loopback(2), then the IP address of the loopback interface is used as the transport address in the hello message.
T/F mplsLdpEntityTargetPeer	1.3.6.1.4.1.738.1.6.5.1.1.2.1.1.17	TruthValue	read-create	If this LDP entity uses targeted peer then set this to true.
IPt mplsLdpEntityTargetPeerAddrType	1.3.6.1.4.1.738.1.6.5.1.1.2.1.1.18	InetAddressType	read-create	The type of the internetwork layer address used for the Extended Discovery. This object indicates how the value of mplsLdpEntityTargetPeerAddr is to be interpreted.
IP mplsLdpEntityTargetPeerAddr	1.3.6.1.4.1.738.1.6.5.1.1.2.1.1.19	InetAddress	read-create	The value of the internetwork layer address used for the Extended Discovery. The value of mplsLdpEntityTargetPeerAddrType specifies how this address is to be interpreted.
MPL mplsLdpEntityLabelType	1.3.6.1.4.1.738.1.6.5.1.1.2.1.1.20	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 mplsLdpEntityDiscontinuityTime	1.3.6.1.4.1.738.1.6.5.1.1.2.1.1.21	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.
STO mplsLdpEntityStorageType	1.3.6.1.4.1.738.1.6.5.1.1.2.1.1.22	StorageType	read-only	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.
T/F mplsLdpEntityWildcardEntity	1.3.6.1.4.1.738.1.6.5.1.1.2.1.1.24	TruthValue	read-create	Specifies whether the LDP Entity is to be used for accepting 'unsolicited' Hello messages that include the R bit. The value of this object is ignored unless mplsLdpEntityTargetedPeer is set to true mplsLdpEntityTargetedPeerAddr is set to 0.
ROW mplsLdpEntityRowStatus	1.3.6.1.4.1.738.1.6.5.1.1.2.1.1.25	RowStatus	read-create	An object that allows entries in this table to be created and deleted using the RowStatus convention. Once the 'mplsLdpEntityAdminStatus' object has the value of 'up' and this object has the value of 'active' then the Entity will atttempt to contact an LDP Peer. If the value of this object is changed to 'notInService', then the Entity looses contact with the LDP Peer and all information related to that Peer must be removed from the MIB. This has the same effect as changing 'mplsLdpEntityAdminStatus' from 'enable' to 'disable'. When this object is set to 'active' and the value of the 'mplsLdpEntityAdminStatus' is 'enable' then this Entity will attempt to contact the Peer and establish new sessions.
mplsLdpEntityIndexNextTable	1.3.6.1.4.1.738.1.6.5.1.1.2.2		not-accessible	This table contains the next available values of mplsLdpEntityIndex for all entities.
mplsLdpEntityIndexNextEntry	1.3.6.1.4.1.738.1.6.5.1.1.2.2.1		not-accessible	An entry in this table represents the next available mplsLdpEntityIndex for a specific LDP entity. This MIB table is indexed by the PRVT-LDP entity Index.
U32 mplsLdpEntityIndexNext	1.3.6.1.4.1.738.1.6.5.1.1.2.2.1.1	Unsigned32	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. To obtain the mplsLdpEntityIndex 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.
mplsLdpEntityStatsTable	1.3.6.1.4.1.738.1.6.5.1.1.2.4		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.
mplsLdpEntityStatsEntry	1.3.6.1.4.1.738.1.6.5.1.1.2.4.1		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 mplsLdpEntityStatsSessionAttemptsEx	1.3.6.1.4.1.738.1.6.5.1.1.2.4.1.1	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.

This is the EXACT value for the ATM Session Parameter, field N (for Number of label range components). The ATM Session Parameter is an optional parameter in the Initialization Message. The description from rfc3036.txt is: 'N, Number of label range components Specifies the number of ATM Label Range Components included in the TLV.' Please refer to the following reference for a complete description of this feature.
INT mplsLdpEntityAtmVcDirectionality	1.3.6.1.4.1.738.1.6.5.1.4.1.1.1.4	INTEGER	read-only	If the value of this object is 'bidirectional(0)', a given VCI, within a given VPI, is used as a label for both directions independently. If the value of this object is 'unidirectional(1)', a given VCI within a VPI designates one direction. This is the EXACT value for the ATM Session Parameter, field D (for VC Directionality). The ATM Session Parameter is an optional parameter in the Initialization Message. The description from rfc3036.txt is: 'D, VC Directionality A value of 0 specifies bidirectional VC capability, meaning the LSR can (within a given VPI) support the use of a given VCI as a label for both link directions independently. A value of 1 specifies unidirectional VC capability, meaning (within a given VPI) a given VCI may appear in a label mapping for one direction on the link only. When either or both of the peers specifies unidirectional VC capability, both LSRs use unidirectional VC label assignment for the link as follows. The LSRs compare their LDP Identifiers as unsigned integers. The LSR with the larger LDP Identifier may assign only odd-numbered VCIs in the VPI/VCI range as labels. The system with the smaller LDP Identifier may assign only even-numbered VCIs in the VPI/VCI range as labels.' Please refer to the following reference for a complete description of this feature.

mplsLdpEntityAtmLRTable	1.3.6.1.4.1.738.1.6.5.1.4.1.2		not-accessible	The MPLS LDP Entity ATM Label Range (LR) Table. The purpose of this table is to provide a mechanism for configuring a contiguous range of vpi's with a contiguous range of vci's, or a 'label range' for LDP Entities. LDP Entities which use ATM must have at least one entry in this table. There must exist at least one entry in this table for every LDP Entity that has 'mplsLdpEntityLabelType' object with a value of 'atmSessionParameters'.
mplsLdpEntityAtmLREntry	1.3.6.1.4.1.738.1.6.5.1.4.1.2.1		not-accessible	A row in the LDP Entity ATM Label Range Table. One entry in this table contains information on a single range of labels represented by the configured Upper and Lower Bounds VPI/VCI pairs. These are the same data used in the Initialization Message. NOTE: The ranges for a specific LDP Entity are UNIQUE and non-overlapping. For example, for a specific LDP Entity index, there could be one entry having LowerBound vpi/vci == 0/32, and UpperBound vpi/vci == 0/100, and a second entry for this same interface with LowerBound vpi/vci == 0/101 and UpperBound vpi/vci == 0/200. However, there could not be a third entry with LowerBound vpi/vci == 0/200 and UpperBound vpi/vci == 0/300 because this label range overlaps with the second entry (i.e., both entries now have 0/200). A row will not become active unless a unique and non-overlapping range is specified. At least one label range entry for a specific LDP Entity MUST include the default VPI/VCI values denoted in the LDP Entity Table. A request to create a row with an overlapping range should result in an inconsistentValue error.

The value of zero means that the InterfaceIndex is not known. For example, if the InterfaceIndex is created subsequent to the Frame Relay Label's creation, then it would not be known. However, if the InterfaceIndex is known, then it must be represented by this value. If an InterfaceIndex becomes known, then the network management entity (e.g., SNMP agent) responsible for this object MUST change the value from 0 (zero) to the value of the InterfaceIndex. If an Frame Relay Label is being used in forwarding data, then the value of this object MUST be the InterfaceIndex.
