Description: GMPLS-LABEL-MIB module

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 GMPLS-LABEL-MIB?

GMPLS-LABEL-MIB is an IETF standards-track, vendor-neutral MIB defining managed objects for labels used within Generalized MPLS (GMPLS) systems, part of the broader IETF GMPLS/MPLS-TE MIB family. It exposes a label table covering different label types and subtypes, including generic freeform labels, port/wavelength labels for optical/DWDM interfaces, and SONET/SDH virtual-container labels. It is primarily a control-plane configuration/state monitoring MIB rather than a hardware-sensor MIB, letting an operator verify that label assignments on GMPLS-capable interfaces match provisioning and detect label-type mismatches that would break a GMPLS-signaled path. It explicitly belongs to the GMPLS MIB suite alongside modules like MPLS-TE-MIB and GMPLS-TE-MIB, and it relies on IF-MIB for identifying the associated interfaces. It is typically deployed on GMPLS-enabled optical, SONET/SDH, or wavelength-switching routers in service-provider transport networks. Engineers implementing or auditing this functionality typically reference the GMPLS-LABEL-MIB RFC/standard documentation for the authoritative specification.

IPNetwork Monitor allows you to monitor SNMP objects defined in GMPLS-LABEL-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
GMPLS-enabled optical/SONET/SDH transport router or switch

Monitoring Examples

An administrator would poll gmplsLabelTable (via gmplsLabelEntry/gmplsSublabelIndex) and check gmplsLabelType/gmplsLabelSubtype together with gmplsPortWavelengthLabel to confirm a given interface's assigned wavelength matches its provisioned lambda. Checking gmplsSonetSdhSignalIndex and gmplsSdhVc would similarly reveal whether a SONET/SDH virtual-container label is correctly mapped, with a mismatch signaling a misconfigured or failed label-switched path.

What Can Be Monitored

GMPLS label type and subtype assignment
wavelength label per port
SONET/SDH virtual-container label mapping

OIDs

OID symbolic	OID numeric	Type	Access	Description
gmplsLabelMIB	1.3.6.1.3.0			This MIB module contains managed object definitions for labels within GMPLS systems.
gmplsLabelObjects	1.3.6.1.3.0.0
gmplsLabelTable	1.3.6.1.3.0.0.1		not-accessible	Table of GMPLS Labels. This table extends mplsLabelTable to handle the more complex label forms required for GMPLS. Each entry in this table represents an individual GMPLS label value. Labels in the tables in other MIBs are referred to using index entries into mplsLabelTable. The indexing of this table is identical. In effect, this table taken together with mplsLabelTable provides an integer mapping for label values that may be more complex than simple integers.
gmplsLabelEntry	1.3.6.1.3.0.0.1.1		not-accessible	An entry in this table extends the label defintion in mplsLabelTable for use with certain types of switching appropriate to GMPLS.
U32 gmplsSublabelIndex	1.3.6.1.3.0.0.1.1.1	Unsigned32	read-only	In conjunction with mplsLabelInterface and mplsLabelIndex, this object uniquely identifies this row. This sub-index allows a single GMPLS label to be defined as a concatenation of labels. This is particularly useful in TDM. The ordering of sub-labels is strict with the sub-label with lowest gmplsSublabelIndex appearing first. Note that all sub-labels of a single GMPLS label must share the same mplsLabelInterface and mplsLabelIndex values. For labels that are not composed of concatenated sub-labels, this value should be set to zero.
GMP gmplsLabelType	1.3.6.1.3.0.0.1.1.2	GmplsGeneralizedLabelTypes	read-create	Identifies the type of this label as it appears in a Generalized Label. This object has meaning only if the value of mplsLabelType is other(1).
GMP gmplsLabelSubtype	1.3.6.1.3.0.0.1.1.3	GmplsGeneralizedLabelSubtypes	read-create	Subtype to help determine which of the subsequent fields should be used to form the Generalized Label.
U32 gmplsPortWavelengthLabel	1.3.6.1.3.0.0.1.1.4	Unsigned32	read-create	The value of a Port or Wavelength Label when carried as a Generalized Label. Only valid if mplsLabelType is set to other(1), gmplsLabelType is set to generalizedLabel(2), and gmplsLabelSubtype is set to portWavelengthLabel(2).
INT gmplsFreeformLength	1.3.6.1.3.0.0.1.1.5	INTEGER	read-create	The length of a freeform Generalized Label indicated in the gmplsFreeformLabel object. Only valid if mplsLabelType is set to other(1), gmplsLabelType is set to generalizedLabel(2), and gmplsLabelSubtype is set to freeformGeneralizedLabel(3).
GMP gmplsFreeformLabel	1.3.6.1.3.0.0.1.1.6	GmplsFreeformLabel	read-create	The value of a freeform Generalized Label that does not conform to one of the standardized label encoding or that an implementation chooses to represent as an octet string without further decoding. The length of this object is given by the value of gmplsFreeformLength. Only valid if mplsLabelType is set to other(1), gmplsLabelType is set to generalizedLabel(2), and gmplsLabelSubtype is set to freeformGeneralizedLabel(3).
INT gmplsSonetSdhSignalIndex	1.3.6.1.3.0.0.1.1.7	INTEGER	read-create	The Signal Index value (S) of a Sonet or SDH Generalized Label. 0 indicates that this field is non-significant. Only valid if mplsLabelType is set to other(1), gmplsLabelType is set to generalizedLabel(2), and gmplsLabelSubtype is set to sonetLabel(4) or sdhLabel(5).
INT gmplsSdhVc	1.3.6.1.3.0.0.1.1.8	INTEGER	read-create	The VC Indicator (U) of an SDH Generalized Label. 0 indicates that this field is non- significant. Only valid if mplsLabelType is set to other(1), gmplsLabelType is set to generalizedLabel(2), and gmplsLabelSubtype is set to sdhLabel(5).
INT gmplsSdhVcBranch	1.3.6.1.3.0.0.1.1.9	INTEGER	read-create	The VC Branch Indicator (K) of an SDH Generalized Label. 0 indicates that this field is non-significant. Only valid if mplsLabelType is set to other(1), gmplsLabelType is set to generalizedLabel(2), and gmplsLabelSubtype is set to sdhLabel(5).
INT gmplsSonetSdhBranch	1.3.6.1.3.0.0.1.1.10	INTEGER	read-create	The Branch Indicator (L) of a Sonet or SDH Generalized Label. 0 indicates that this field is non-significant. Only valid if mplsLabelType is set to other(1), gmplsLabelType is set to generalizedLabel(2), and gmplsLabelSubtype is set to sonetLabel(4) or SdhLabel(5).
INT gmplsSonetSdhGroupBranch	1.3.6.1.3.0.0.1.1.11	INTEGER	read-create	The Group Branch Indicator (M) of a Sonet or SDH Generalized Label. 0 indicates that this field is non-significant. Only valid if mplsLabelType is set to other(1), gmplsLabelType is set to generalizedLabel(2), and gmplsLabelSubtype is set to sonetLabel(4) or sdhLabel(5).
U32 gmplsWavebandId	1.3.6.1.3.0.0.1.1.12	Unsigned32	read-create	The waveband identifier component of a waveband label. Only valid if mplsLabelType is set to other(1), gmplsLabelType is set to generalizedLabel(2), and gmplsLabelSubtype is set to wavebandLabel(6).

U32 gmplsWavebandEndLabel	1.3.6.1.3.0.0.1.1.14	Unsigned32	read-create	The end label component of a waveband label. Only valid if mplsLabelType is set to other(1), gmplsLabelType is set to generalizedLabel(2), and gmplsLabelSubtype is set to wavebandLabel(6).
