What Is MPLS-TE-MIB?

MPLS-TE-MIB is a vendor-neutral IETF-derived MIB module that defines management objects for MPLS Traffic Engineering, covering the configuration and status of TE tunnels (LSPs) as specified in RSVP-TE and CR-LDP extension drafts referenced in its module description. It exposes tunnel-level configuration and operational objects in mplsTunnelTable/mplsTunnelEntry, including tunnel index/instance, ingress and egress LSR identifiers (mplsTunnelIngressLSRId, mplsTunnelEgressLSRId), tunnel name, and whether a tunnel is configured versus actively signaled (mplsTunnelConfigured, mplsTunnelActive). Its monitoring value is centered on the operational software/control-plane status of traffic-engineered paths across an MPLS network: verifying whether a specific tunnel is up and carrying traffic (mplsTunnelActive), which TE distribution protocol signaled it (mplsTunnelTEDistProto), and whether hop-count limits (mplsTunnelMaxHops) are being respected, which is essential for diagnosing a failed or suboptimal LSP. It builds on and complements the base MPLS LSR/label MIBs and the underlying RSVP/CR-LDP signaling protocols referenced in its description, rather than standing alone, and operators bringing up a new TE deployment commonly keep an MPLS-TE-MIB reference nearby to confirm which of these companion modules a given object depends on. It is deployed on MPLS-enabled provider-edge and core routers from any vendor implementing MPLS-TE, where network operations teams monitor tunnel state to ensure traffic-engineered paths remain established as designed.

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

  • TE tunnel configured vs. active state
  • tunnel ingress/egress LSR identity
  • TE signaling/distribution protocol
  • tunnel max-hop constraint
  • tunnel name/identification

Supported Devices

  • vendor-neutral, standards-based MIB, not tied to a specific manufacturer
  • MPLS-enabled routers (provider-edge and core)

Monitoring Examples

An operator would poll mplsTunnelTable/mplsTunnelEntry, keyed by mplsTunnelIndex and mplsTunnelInstance, and check mplsTunnelActive against mplsTunnelConfigured for a tunnel identified by mplsTunnelIngressLSRId and mplsTunnelEgressLSRId to confirm whether a configured LSP is actually up and signaled. A tunnel showing mplsTunnelConfigured true but mplsTunnelActive false would indicate the TE tunnel failed to establish, prompting investigation into path constraints or a failure along the LSP; mplsTunnelName provides the human-readable label used to identify the tunnel during troubleshooting.

OID symbolicOID numericTypeAccessDescription
mplsTeMIB1.3.6.1.3.95This MIB module contains managed object definitions for MPLS Traffic Engineering (TE) as defined in: Extensions to RSVP for LSP Tunnels, Awduche et al, Internet Draft , August 2000; Constraint- Based LSP Setup using LDP, B. Jamoussi, Internet Draft , July 2000; Requirements for Traffic Engineering Over MPLS, Awduche, D., J. Malcolm, J., Agogbua, J., O'Dell, M., J. McManus, , September 1999.
mplsTeScalars1.3.6.1.3.95.1
U32 mplsTunnelConfigured1.3.6.1.3.95.1.1Unsigned32read-onlyThe number of tunnels configured on this device. A tunnel is considered configured if the mplsTunnelRowStatus is active(1).
U32 mplsTunnelActive1.3.6.1.3.95.1.2Unsigned32read-onlyThe number of tunnels active on this device. A tunnel is considered active if the mplsTunnelOperStatus is up(1).
BIT mplsTunnelTEDistProto1.3.6.1.3.95.1.3Bitsread-onlyThe traffic engineering distribution protocol(s) used by this LSR. Note that an LSR may support more than one distribution protocols simultaneously.
U32 mplsTunnelMaxHops1.3.6.1.3.95.1.4Unsigned32read-onlyThe maximum number of hops that can be specified for a tunnel on this device.
mplsTeObjects1.3.6.1.3.95.2
I32 mplsTunnelIndexNext1.3.6.1.3.95.2.1Integer32read-onlyThis object contains the next appropriate value to be used for mplsTunnelIndex when creating entries in mplsTunnelTable. If the number of unassigned entries is exhausted, a retrival operation will return a value of 0. This object may also return a value of 0 when the LSR is unable to accept conceptual row creation, for example, if the mplsTunnelTable is implemented as read-only. To obtain the value of mplsTunnelIndex for a new entry, the manager must first issue a management protocol retrieval operation to obtain the current value of this object. The agent should modify the value to reflect the next unassigned index after each retrieval operation. After a manager retrieves a value the agent will determine through its local policy when this index value will be made available for reuse.
mplsTunnelTable1.3.6.1.3.95.2.2not-accessibleThe mplsTunnelTable allows new MPLS tunnels to be created between an LSR and a remote endpoint, and existing tunnels to be reconfigured or removed. Note that only point-to-point tunnel segments are supported, although multi-point-to-point and point- to-multi-point connections are supported by an LSR acting as a cross-connect. Each MPLS tunnel can thus have one out-segment originating at this LSR and/or one in-segment terminating at this LSR.
mplsTunnelEntry1.3.6.1.3.95.2.2.1not-accessibleAn entry in this table represents an MPLS tunnel. An entry can be created by a network administrator or by an SNMP agent as instructed by an MPLS signaling protocol. Whenever a new entry is created with mplsTunnelIsIf set to true(1), then a corresponding entry is created in ifTable as well (see RFC 2233). The ifType of this entry is mplsTunnel(150).
MPL mplsTunnelIndex1.3.6.1.3.95.2.2.1.1MplsTunnelIndexnot-accessibleUniquely identifies this row.
MPL mplsTunnelInstance1.3.6.1.3.95.2.2.1.2MplsTunnelInstanceIndexnot-accessibleUniquely identifies an instance of a tunnel. It is useful to identify multiple instances of tunnels for the purposes of backup and parallel tunnels.
MPL mplsTunnelIngressLSRId1.3.6.1.3.95.2.2.1.3MplsLsrIdnot-accessibleThe purpose of this object is to uniquely identity a tunnel within a network. When the MPLS signalling protoocol is rsvp(2) this value should mimic the Extended Tunnel Id field in the Session object. When the MPLS signalling protoocol is crldp(3) this value should mimic the Ingress LSR Router ID field in the LSPID TLV object.
MPL mplsTunnelEgressLSRId1.3.6.1.3.95.2.2.1.4MplsLsrIdread-onlySpecifies the egress LSR Id.
STR mplsTunnelName1.3.6.1.3.95.2.2.1.5DisplayStringread-createThe canonical name assigned to the tunnel. This name can be used to refer to the tunnel on the LSR�s console port. If mplsTunnelIsIf is set to true then the ifName of the interface corresponding to this tunnel should have a value equal to mplsTunnelName. Also see the description of ifName in RFC 2233.
STR mplsTunnelDescr1.3.6.1.3.95.2.2.1.6DisplayStringread-createA textual string containing information about the tunnel. If there is no description this object contains a zero length string.
T/F mplsTunnelIsIf1.3.6.1.3.95.2.2.1.7TruthValueread-createDenotes whether or not this tunnel corresponds to an interface represented in the interfaces group table. Note that if this variable is set to true then the ifName of the interface corresponding to this tunnel should have a value equal to mplsTunnelName. Also see the description of ifName in RFC 2233.
NUM mplsTunnelIfIndex1.3.6.1.3.95.2.2.1.8InterfaceIndexOrZeroread-onlyIf mplsTunnelIsIf is set to true, then this value contains the LSR-assigned ifIndex which corresponds to an entry in the interfaces table. Otherwise this variable should contain the value of zero indicating that a valid ifIndex was not assigned to this tunnel interface.
NUM mplsTunnelXCPointer1.3.6.1.3.95.2.2.1.9RowPointerread-createThis variable points to a row in the mplsXCTable. This table identifies the segments that compose this tunnel, their characteristics, and relationships to each other. A value of zeroDotZero indicates that no LSP has been associated with this tunnel yet.
INT mplsTunnelSignallingProto1.3.6.1.3.95.2.2.1.10INTEGERread-createThe signaling protocol, if any, which was used to setup this tunnel.
INT mplsTunnelSetupPrio1.3.6.1.3.95.2.2.1.11INTEGERread-createIndicates the setup priority of this tunnel.
INT mplsTunnelHoldingPrio1.3.6.1.3.95.2.2.1.12INTEGERread-createIndicates the holding priority for this tunnel.
BIT mplsTunnelSessionAttributes1.3.6.1.3.95.2.2.1.13Bitsread-createThis bitmask indicates optional session values for this tunnel. The following describes these bitfields: fastRerouteThis flag indicates that the any tunnel hop may choose to reroute this tunnel without tearing it down. This flag permits transit routers to use a local repair mechanism which may result in violation of the explicit routing of this tunnel. When a fault is detected on an adjacent downstream link or node, a transit router can reroute traffic for fast service restoration. mergingPermitted This flag permits transit routers to merge this session with other RSVP sessions for the purpose of reducing resource overhead on downstream transit routers, thereby providing better network scalability. isPersistent Indicates whether this tunnel should be restored automatically after a failure occurs. isPinned This flag indicates whether the loose- routed hops of this tunnel are to be pinned. isComputed This flag indicates whether the tunnel path is computed using a constraint-based routing algorithm based on the mplsTunnelHopTable entries. recordRoute This flag indicates whether or not the signaling protocol should remember the tunnel path after it has been signaled.
INT mplsTunnelOwner1.3.6.1.3.95.2.2.1.14INTEGERread-createIndicates which protocol created and is responsible for managing this tunnel. Values rsvp(2) and crldp(3) should not be used at the head-end of a MPLS tunnel.
T/F mplsTunnelLocalProtectInUse1.3.6.1.3.95.2.2.1.15TruthValueread-createIndicates that the local repair mechanism is in use to maintain this tunnel (usually in the face of an outage of the link it was previously routed over).
NUM mplsTunnelResourcePointer1.3.6.1.3.95.2.2.1.16RowPointerread-createThis variable represents a pointer to the traffic parameter specification for this tunnel. This value may point at an entry in the mplsTunnelResourceEntry to indicate which mplsTunnelResourceEntry is to be assigned to this segment. This value may optionally point at an externally defined traffic parameter specification table. A value of zeroDotZero indicates best- effort treatment. By having the same value of this object, two or more segments can indicate resource sharing.
U32 mplsTunnelInstancePriority1.3.6.1.3.95.2.2.1.17Unsigned32read-createThis value indicates which priority, in descending order, with 0 indicating the lowest priority, within a group of tunnel instances. A group of tunnel instances is defined as a set of tunnels with the same mplsTunnelIndex in this table, but with a different mplsTunnelInstance. Tunnel group priorities are used to denote the priority at which a particular tunnel instance will supercede another. Instances of tunnels containing the same mplsTunnelInstancePriority will be used for load sharing.

C32 mplsTunnelStateTransitions1.3.6.1.3.95.2.2.1.26Counter32read-onlySpecifies the number of times the state of this tunnel instance has changed.
U32 mplsTunnelIncludeAnyAffinity1.3.6.1.3.95.2.2.1.27Unsigned32read-createA link satisfies the include-any constraint if and only if the constraint is zero, or the link and the constraint have a resource class in common.
U32 mplsTunnelIncludeAllAffinity1.3.6.1.3.95.2.2.1.28Unsigned32read-createA link satisfies the include-all constraint if and only if the link contains all of the adminstrative groups specified in the constraint.

MPL mplsTunnelPathInUse1.3.6.1.3.95.2.2.1.30MplsPathIndexOrZeroread-createThis value denotes the configured path that was chosen for this tunnel. This value reflects the secondary index into the TunnelHopTable. This path may not exactly match the one in the ARHopTable due to the fact that some CSPF modification may have taken place. See the ARHopTable for the actual path being taken by the tunnel. A value of zero denotes that no path is currently in use or available.
INT mplsTunnelRole1.3.6.1.3.95.2.2.1.31INTEGERread-createThis value signifies the role that this tunnel entry/instance represents. This value MUST be set to head(1) at the originating point of the tunnel. This value MUST be set to transit(2) at transit points along the tunnel, if transit points are supported. This value MUST be set to tail(3) at the terminating point of the tunnel if tunnel tails are supported.
TIK mplsTunnelTotalUpTime1.3.6.1.3.95.2.2.1.32TimeTicksread-createThis value represents the aggregate up time for all instances of this tunnel, if available. If this value is unavailable, it MUST return a value of 0.

STO mplsTunnelStorageType1.3.6.1.3.95.2.2.1.37StorageTyperead-createThis variable indicates the storage type for this object.
U32 mplsTunnelHopListIndexNext1.3.6.1.3.95.2.3Unsigned32read-onlyThis object contains an appropriate value to be used for mplsTunnelHopListIndex when creating entries in the mplsTunnelHopTable. If the number of unassigned entries is exhausted, a retrival operation will return a value of 0. This object may also return a value of 0 when the LSR is unable to accept conceptual row creation, for example, if the mplsTunnelHopTable is implemented as read-only. To obtain the value of mplsTunnelHopListIndex for a new entry in the mplsTunnelHopTable, the manager issues a management protocol retrieval operation to obtain the current value of mplsTunnelHopIndex. After each retrieval operation, the agent should modify the value to reflect the next unassigned index. After a manager retrieves a value the agent will determine through its local policy when this index value will be made available for reuse.
mplsTunnelHopTable1.3.6.1.3.95.2.4not-accessibleThe mplsTunnelHopTable is used to indicate the hops, strict or loose, for an MPLS tunnel defined in mplsTunnelTable, when it is established via signaling, for the outgoing direction of the tunnel. Each row in this table is indexed by mplsTunnelHopListIndex. Each row also has a secondary index mplsTunnelHopIndex corresponding to the next hop that this row corresponds to. The first row in the table is the first hop after the origination point of the tunnel. In case we want to specify a particular interface on the originating LSR of an outgoing tunnel by which we want packets to exit the LSR, we specify this as the first hop for this tunnel in mplsTunnelHopTable.

MPL mplsTunnelHopLspId1.3.6.1.3.95.2.4.1.10MplsLSPIDread-createIf mplsTunnelHopAddrType is set to lspid(4), then this value will contain the LSPID of a tunnel of this hop. The present tunnel being configured is �tunneled� through this hop (using label stacking). This object is otherwise insignificant and should contain a value of 0 to indicate this fact.

If the number of unassigned entries is exhausted, a retrival operation will return a value of 0. This object may also return a value of 0 when the LSR is unable to accept conceptual row creation, for example, if the mplsTunnelTable is implemented as read-only. To obtain the mplsTunnelResourceIndex value for a new entry, the manager must first issue a management protocol retrieval operation to obtain the current value of this object. The agent should modify the value to reflect the next unassigned index after each retrieval operation. After a manager retrieves a value the agent will determine through its local policy when this index value will be made available for reuse.
mplsTunnelResourceTable1.3.6.1.3.95.2.6not-accessibleThe mplsTunnelResourceTable allows a manager to specify which resources are desired for an MPLS tunnel. This table also allows several tunnels to point to a single entry in this table, implying that these tunnels should share resources.
mplsTunnelResourceEntry1.3.6.1.3.95.2.6.1not-accessibleAn entry in this table represents a set of resources for an MPLS tunnel. An entry can be created by a network administrator or by an SNMP agent as instructed by any MPLS signaling protocol.

Note that setting mplsTunnelResourceMaxRate, mplsTunnelResourceMeanRate, and mplsTunnelResourceMaxBurstSize to 0 indicates best- effort treatment. This object is copied to an instance of mplsTrafficParamMaxRate in mplsTrafficParamTable the OID of which is copied into the corresponding mplsInSegmentTrafficParamPtr.
MPL mplsTunnelResourceMeanRate1.3.6.1.3.95.2.6.1.3MplsBitRateread-createThis object is copied into an instance of mplsTrafficParamMeanRate in the mplsTrafficParamTable. The OID of this table entry is then copied into the corresponding mplsInSegmentTrafficParamPtr. When resource allocation is performed as requested by this TSpec object, it is copied into an entry in mplsTrafficParamTable [LSRMIB]: mplsTunnelInMeanRate to mplsTrafficParamMeanRate. The OID of this entry is copied to mplsInSegmentTrafficParamPtr of the corresponding in-segment entry.
MPL mplsTunnelResourceMaxBurstSize1.3.6.1.3.95.2.6.1.4MplsBurstSizeread-createThe maximum burst size in bytes. This object is copied to mplsInSegmentMaxBurstSize of the corresponding in-segment. When resource allocation is performed as requested by this TSpec object, it is copied into an entry in mplsTrafficParamTable [LSRMIB]: mplsTunnelInMaxBurstSize to mplsTrafficParamMaxBurstSize. The OID of this entry is copied to mplsInSegmentTrafficParamPtr of the corresponding in-segment entry.

mplsTunnelARHopTable1.3.6.1.3.95.2.7not-accessibleThe mplsTunnelARHopTable is used to indicate the hops, strict or loose, for an MPLS tunnel defined in mplsTunnelTable, as reported by the MPLS signaling protocol, for the outgoing direction of the tunnel. Each row in this table is indexed by mplsTunnelARHopListIndex. Each row also has a secondary index mplsTunnelARHopIndex, corresponding to the next hop that this row corresponds to. The first row in the table is the first hop after the origination point of the tunnel. In case we want to specify a particular interface on the originating LSR of an outgoing tunnel by which we want packets to exit the LSR, we specify this as the first hop for this tunnel in mplsTunnelARHopTable. Please note that since the information necessary to build entries within this table are not provided by some MPLS signaling protocols, implementation of this table is optional. Furthermore, since the information in this table is actually provided by the MPLS signaling protocol after the path has been set-up, the entries in this table are provided only for observation, and hence, all variables in this table are accessible exclusively as read-only.
mplsTunnelARHopEntry1.3.6.1.3.95.2.7.1not-accessibleAn entry in this table represents a tunnel hop. An entry is created by a network administrator for signaled ERLSP set up by an MPLS signaling protocol.

mplsTunnelCHopTable1.3.6.1.3.95.2.8not-accessibleThe mplsTunnelCHopTable is used to indicate the hops, strict or loose, for an MPLS tunnel defined in mplsTunnelTable, as computed by a constraint- based routing protocol, based on the mplsTunnelHopTable for the outgoing direction of the tunnel. Each row in this table is indexed by mplsTunnelCHopListIndex. Each row also has a secondary index mplsTunnelCHopIndex, corresponding to the next hop that this row corresponds to. The first row in the table is the first hop after the origination point of the tunnel. In case we want to specify a particular interface on the originating LSR of an outgoing tunnel by which we want packets to exit the LSR, we specify this as the first hop for this tunnel in mplsTunnelCHopTable. Please note that since the information necessary to build entries within this table may not be supported by some LSRs, implementation of this table is optional. Furthermore, since the information in this table is actually provided by routing protocol after the path has been computed, the entries in this table are provided only for observation, and hence, all variables in this table are accessible exclusively as read-only.
mplsTunnelCHopEntry1.3.6.1.3.95.2.8.1not-accessibleAn entry in this table represents a tunnel hop. An entry in this table is created by a constraint- based routing protocol based on the hops specified in the corresponding mplsTunnelHopTable.

mplsTeNotifyPrefix1.3.6.1.3.95.3.0
NTF mplsTunnelUp1.3.6.1.3.95.3.0.1This notification is generated when a mplsTunnelOperStatus object for one of the configured tunnels is about to leave the down state and transition into some other state (but not into the notPresent state). This other state is indicated by the included value of mplsTunnelOperStatus.
NTF mplsTunnelDown1.3.6.1.3.95.3.0.2This notification is generated when a mplsTunnelOperStatus object for one of the configured tunnels is about to enter the down state from some other state (but not from the notPresent state). This other state is indicated by the included value of mplsTunnelOperStatus.
NTF mplsTunnelRerouted1.3.6.1.3.95.3.0.3This notification is generated when a tunnel is rerouted or re-optimized. If the Actual Path is used, then this object MAY contain the new path for this tunnel some time after this trap is issued by the agent.
