What Is MPLS-LDP-GENERIC-MIB?

MPLS-LDP-GENERIC-MIB is an IETF standards-track, vendor-neutral MIB defining generic managed objects for the Label Distribution Protocol (LDP) as used with MPLS over Ethernet-type Layer 2 interfaces. It belongs to the MPLS control-plane networking technology area. It exposes objects related to LDP interfaces and generic (non-ATM) label-space configuration used in label distribution for MPLS forwarding. Rather than hardware health, it is used to monitor protocol/software-level status on the control plane — whether LDP is correctly bound to an interface and its generic label range is configured — complementing the runtime session/adjacency state tracked elsewhere. It explicitly depends on and complements MPLS-LDP-MIB, covering the generic (Ethernet) media case as a companion to that MIB's ATM-specific counterpart. It's deployed on MPLS-enabled routers/label switch routers within a service-provider or enterprise MPLS network, as formalized in the MPLS-LDP-GENERIC-MIB RFC that defines these generic LDP objects.

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

  • LDP interface bindings
  • generic label space configuration
  • per-interface LDP enablement

Supported Devices

  • vendor-neutral, standards-based MIB, not tied to a specific manufacturer
  • MPLS-enabled router / label switch router (LSR)

Monitoring Examples

No sample_objects were provided for this MIB in the source data, so no specific object/table names can be grounded from it directly. In practice this module would be consulted alongside MPLS-LDP-MIB's session and interface tables to confirm that generic (Ethernet) interfaces have the expected LDP label space bound and that per-interface LDP is enabled where intended. Without concrete object names supplied, any more specific technical walkthrough would be speculative.

mplsLdpGenericMIB1.3.6.1.2.1.10.9999.6This MIB contains managed object definitions for the 'Multiprotocol Label Switching, Label Distribution Protocol, LDP' document which use as their Layer 2 ethernet.

mplsLdpGenModuleFullCompliance1.3.6.1.2.1.10.9999.6.3.2.1The Module is implemented with support for read-create and read-write. In other words, both monitoring and configuration are available when using this MODULE-COMPLIANCE.
mplsLdpGenModuleROCompliance1.3.6.1.2.1.10.9999.6.3.2.2The Module is implemented with support for read-only. In other words, only monitoring is available by implementing this MODULE-COMPLIANCE.

mplsLdpEntityGenLRTable1.3.6.1.4.1.9.3.65.1.2.5.1not-accessibleThe MPLS LDP Entity Generic Label Range Table. The purpose of this table is to provide a mechanism for configurating a contiguous range of generic labels, or a 'label range' for LDP Entities. LDP Entities which use Generic Labels must have at least one entry in this table.
mplsLdpEntityGenLREntry1.3.6.1.4.1.9.3.65.1.2.5.1.1not-accessibleA row in the LDP Entity Generic Label Range Table. One entry in this table contains information on a single range of labels represented by the configured Upper and Lower Bounds pairs. NOTE: there is NO corresponding LDP message which relates to the information in this table, however, this table does provide a way for a user to 'reserve' a generic label range. NOTE: The ranges for a specific LDP Entity are UNIQUE and non-overlapping. A row will not be created unless a unique and non-overlapping range is specified.
U32 mplsLdpEntityGenLRMin1.3.6.1.4.1.9.3.65.1.2.5.1.1.1Unsigned32not-accessibleThe minimum label configured for this range.
U32 mplsLdpEntityGenLRMax1.3.6.1.4.1.9.3.65.1.2.5.1.1.2Unsigned32not-accessibleThe maximum label configured for this range.
NUM mplsLdpEntityGenIfIndexOrZero1.3.6.1.4.1.9.3.65.1.2.5.1.1.3InterfaceIndexOrZeroread-createThis value represents either the InterfaceIndex of the 'ifLayer' where these Generic Label would be created, or 0 (zero). The value of zero means that the InterfaceIndex is not known. For example, if the InterfaceIndex is created subsequent to the Generic 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.
STO mplsLdpEntityGenLRStorageType1.3.6.1.4.1.9.3.65.1.2.5.1.1.4StorageTyperead-createThe storage type for this entry.
ROW mplsLdpEntityGenLRRowStatus1.3.6.1.4.1.9.3.65.1.2.5.1.1.5RowStatusread-createAn object that allows entries in this table to be created and deleted using the RowStatus convention. There must exist at least one entry in this table for every LDP Entity that has a generic label configured. NOTE: This RowStatus object should have the same value of the 'mplsLdpEntityRowStatus' related to this entry.
