Description: Extends the MPLS LDP MIB for Label Distribution Protocol implementations that use the per-platform (global) label space.

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

What Is MPLS-LDP-GENERIC-STD-MIB?

MPLS-LDP-GENERIC-STD-MIB is the standard IETF MPLS Working Group MIB (RFC 3815) supplementing MPLS-LDP-STD-MIB with the Generic Label range used for platform-wide (non-ATM/Frame-Relay) label spaces. Its label-range table, keyed by LDP entity, records min/max label, label space, an optional ifIndex, storage type, and row status. As a configuration MIB it lets an administrator confirm the generic label-space range assigned to an LDP entity on a router implementing IETF LDP. It is deployed on routers implementing IETF LDP (MPLS-LDP-STD-MIB, RFC 3815). Engineers can download the MPLS-LDP-GENERIC-STD-MIB file directly to load it into their MIB browser.

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

Routers implementing IETF LDP (MPLS-LDP-STD-MIB, RFC 3815)

Monitoring Examples

An administrator checks mplsLdpEntityGenericLRMin and ...LRMax to confirm the generic label-space range assigned to an LDP entity on a router.

What Can Be Monitored

mplsLdpGenericStdMIB	1.3.6.1.2.1.10.166.7			Copyright (C) The Internet Society (year). The initial version of this MIB module was published in RFC 3815. For full legal notices see the RFC itself or see: http://www.ietf.org/copyrights/ianamib.html This MIB contains managed object definitions for configuring and monitoring the Multiprotocol Label Switching (MPLS), Label Distribution Protocol (LDP), utilizing ethernet as the Layer 2 media.
mplsLdpGenericObjects	1.3.6.1.2.1.10.166.7.1
mplsLdpEntityGenericObjects	1.3.6.1.2.1.10.166.7.1.1
mplsLdpEntityGenericLRTable	1.3.6.1.2.1.10.166.7.1.1.1		not-accessible	The MPLS LDP Entity Generic Label Range (LR) 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. In other words, this table 'extends' the mpldLdpEntityTable for Generic Labels.
mplsLdpEntityGenericLREntry	1.3.6.1.2.1.10.166.7.1.1.1.1		not-accessible	A row in the LDP Entity Generic Label Range (LR) 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 mplsLdpEntityGenericLRMin	1.3.6.1.2.1.10.166.7.1.1.1.1.1	Unsigned32	not-accessible	The minimum label configured for this range.
U32 mplsLdpEntityGenericLRMax	1.3.6.1.2.1.10.166.7.1.1.1.1.2	Unsigned32	not-accessible	The maximum label configured for this range.
INT mplsLdpEntityGenericLabelSpace	1.3.6.1.2.1.10.166.7.1.1.1.1.3	INTEGER	read-create	This value of this object is perPlatform(1), then this means that the label space type is per platform. If this object is perInterface(2), then this means that the label space type is per Interface.
NUM mplsLdpEntityGenericIfIndexOrZero	1.3.6.1.2.1.10.166.7.1.1.1.1.4	InterfaceIndexOrZero	read-create	This 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. 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 mplsLdpEntityGenericLRStorageType	1.3.6.1.2.1.10.166.7.1.1.1.1.5	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.
ROW mplsLdpEntityGenericLRRowStatus	1.3.6.1.2.1.10.166.7.1.1.1.1.6	RowStatus	read-create	The status of this conceptual row. All writable objects in this row may be modified at any time, however, as described in detail in the section entitled, 'Changing Values After Session Establishment', and again described in the DESCRIPTION clause of the mplsLdpEntityAdminStatus object, if a session has been initiated with a Peer, changing objects in this table will wreak havoc with the session and interrupt traffic. To repeat again: the recommended procedure is to set the mplsLdpEntityAdminStatus to down, thereby explicitly causing a session to be torn down. Then, change objects in this entry, then set the mplsLdpEntityAdminStatus to enable which enables a new session to be initiated. There must exist at least one entry in this table for every LDP Entity that has a generic label configured.
mplsLdpGenericConformance	1.3.6.1.2.1.10.166.7.2
mplsLdpGenericGroups	1.3.6.1.2.1.10.166.7.2.1
mplsLdpGenericGroup	1.3.6.1.2.1.10.166.7.2.1.1			Objects that apply to all MPLS LDP implementations using Generic Labels as the Layer 2.
mplsLdpGenericCompliances	1.3.6.1.2.1.10.166.7.2.2
mplsLdpGenericModuleFullCompliance	1.3.6.1.2.1.10.166.7.2.2.1			The 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.
mplsLdpGenericModuleReadOnlyCompliance	1.3.6.1.2.1.10.166.7.2.2.2			The Module is implemented with support for read-only. In other words, only monitoring is available by implementing this MODULE-COMPLIANCE.
