Description: Defines managed objects for MPLS label-controlled Frame Relay interfaces.

IPNetwork Monitor uses several OIDs from this MIB in network discovery and polling the applicable devices. Start monitoring MPLS-LC-FR-STD-MIB with a free 30-day trial of IPNetwork Monitor.

What Is MPLS-LC-FR-STD-MIB?

This is a standards-based IETF MIB (RFC 4368, building on RFC 3034) that defines managed objects for MPLS Label-Controlled Frame Relay interfaces, covering the mapping of Frame Relay DLCI ranges to MPLS label-switched paths. It exposes interface configuration objects specifying traffic and control DLCI ranges (minimum/maximum) and row status for provisioning these label-controlled Frame Relay interfaces. Its monitoring value is centered on configuration/provisioning correctness—confirming DLCI range assignments are properly configured and active (via row status)—rather than hardware health, since this is a control-plane/protocol configuration MIB; it also defines notifications for interface-related events. It is explicitly built on top of MPLS architecture standards and Frame Relay interface conventions defined elsewhere in the IETF MPLS MIB family. It would be deployed on carrier-grade routers that interconnect Frame Relay and MPLS networks, a technology combination common in legacy service provider WAN environments. Engineers can download the MPLS-LC-FR-STD-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in MPLS-LC-FR-STD-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
carrier router interconnecting Frame Relay and MPLS networks

Monitoring Examples

An operator would check mplsLcFrStdInterfaceConfTable, keyed by an interface index, to confirm mplsLcFrStdTrafficMinDlci/mplsLcFrStdTrafficMaxDlci and mplsLcFrStdCtrlMinDlci/mplsLcFrStdCtrlMaxDlci match the intended DLCI range provisioned for MPLS label-control on that interface. The mplsLcFrStdInterfaceConfRowStatus object confirms whether the configuration entry is active; a row stuck in notReady or notInService would indicate a failed provisioning attempt. mplsLcFrStdNotifications would alert an operator to relevant state changes on these label-controlled Frame Relay interfaces.

What Can Be Monitored

OIDs

OID symbolic	OID numeric	Type	Access	Description
mplsLcFrStdMIB	1.3.6.1.2.1.10.166.10			This MIB module contains managed object definitions for MPLS Label-Controlled Frame-Relay interfaces as defined in (RFC3034). Copyright (C) The Internet Society (2006). This version of this MIB module is part of RFC 4368; see the RFC itself for full legal notices.
mplsLcFrStdNotifications	1.3.6.1.2.1.10.166.10.0
mplsLcFrStdObjects	1.3.6.1.2.1.10.166.10.1
mplsLcFrStdInterfaceConfTable	1.3.6.1.2.1.10.166.10.1.1		not-accessible	This table specifies per-interface MPLS LC-FR capability and associated information. In particular, this table sparsely extends the MPLS-LSR-STD-MIB's mplsInterfaceConfTable.
mplsLcFrStdInterfaceConfEntry	1.3.6.1.2.1.10.166.10.1.1.1		not-accessible	An entry in this table is created by an LSR for every interface capable of supporting MPLS LC-FR. Each entry in this table will exist only if a corresponding entry in ifTable and mplsInterfaceConfTable exists. If the associated entries in ifTable and mplsInterfaceConfTable are deleted, the corresponding entry in this table must also be deleted shortly thereafter.
DLC mplsLcFrStdTrafficMinDlci	1.3.6.1.2.1.10.166.10.1.1.1.1	DLCI	read-create	This is the minimum DLCI value over which this LSR is willing to accept traffic on this interface.
DLC mplsLcFrStdTrafficMaxDlci	1.3.6.1.2.1.10.166.10.1.1.1.2	DLCI	read-create	This is the max DLCI value over which this LSR is willing to accept traffic on this interface.
DLC mplsLcFrStdCtrlMinDlci	1.3.6.1.2.1.10.166.10.1.1.1.3	DLCI	read-create	This is the min DLCI value over which this LSR is willing to accept control traffic on this interface.
DLC mplsLcFrStdCtrlMaxDlci	1.3.6.1.2.1.10.166.10.1.1.1.4	DLCI	read-create	This is the max DLCI value over which this LSR is willing to accept control traffic on this interface.
ROW mplsLcFrStdInterfaceConfRowStatus	1.3.6.1.2.1.10.166.10.1.1.1.5	RowStatus	read-create	This object is used to create and delete entries in this table. When configuring entries in this table, the corresponding ifEntry and mplsInterfaceConfEntry MUST exist beforehand. If a manager attempts to create an entry for a corresponding mplsInterfaceConfEntry that does not support LC-FR, the agent MUST return an inconsistentValue error. If this table is implemented read-only, then the agent must set this object to active(1) when this row is made active. If this table is implemented writable, then an agent MUST not allow modification to its objects once this value is set to active(1), except to mplsLcFrStdInterfaceConfRowStatus and mplsLcFrStdInterfaceConfStorageType.
STO mplsLcFrStdInterfaceConfStorageType	1.3.6.1.2.1.10.166.10.1.1.1.6	StorageType	read-create	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.
mplsLcFrStdConformance	1.3.6.1.2.1.10.166.10.2
mplsLcFrStdCompliances	1.3.6.1.2.1.10.166.10.2.1
mplsLcFrStdModuleFullCompliance	1.3.6.1.2.1.10.166.10.2.1.1			Compliance statement for agents that provide full support for MPLS-LC-FR-STD-MIB. Such devices can be monitored and also be configured using this MIB module.
mplsLcFrStdModuleReadOnlyCompliance	1.3.6.1.2.1.10.166.10.2.1.2			Compliance requirement for implementations that only provide read-only support for MPLS-LC-FR-STD-MIB. Such devices can be monitored but cannot be configured using this MIB module.
mplsLcFrStdGroups	1.3.6.1.2.1.10.166.10.2.2
mplsLcFrStdIfGroup	1.3.6.1.2.1.10.166.10.2.2.1			Collection of objects needed for MPLS LC-FR interface configuration.
