Description: Defines IETF draft objects for pseudowire encapsulation over L2TPv3 tunnel configuration and session management.

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 PW-L2TPv3-DRAFT-00-MIB?

PW-L2TPv3-DRAFT-00-MIB is an IETF PWE3 working group draft MIB (targeted for eventual RFC publication) that defines managed objects for pseudowire encapsulation carried over L2TPv3 tunnels, complementing the generic pseudowire framework. As a vendor-neutral standards-track module, it is expected to expose configuration objects for L2TPv3 tunnel and session parameters used to transport a pseudowire, though no concrete object names were captured for this batch. Its intended monitoring role is tracking L2TPv3 tunnel/session state and pseudowire binding health — configuration correctness and session establishment status — as part of overall pseudowire service assurance rather than exposing hardware sensor data. It explicitly complements the PW-STD-MIB, which defines the generic pseudowire objects this module extends specifically for L2TPv3 as the underlying tunneling mechanism. It would typically be deployed on provider edge routers offering L2TPv3-based pseudowire services as an alternative to MPLS pseudowires, per the PW-L2TPv3-DRAFT-00-MIB reference draft published by the IETF PWE3 working group.

IPNetwork Monitor allows you to monitor SNMP objects defined in PW-L2TPv3-DRAFT-00-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.

Monitoring Examples

No concrete object names were provided in the source material for this MIB, so a specific polling scenario cannot be described with confidence; in general use, an operator would expect tables covering L2TPv3 tunnel/session identifiers and pseudowire binding status to verify a given pseudowire is correctly mapped to its underlying L2TPv3 session.

OID symbolic	OID numeric	Type	Access	Description
pwL2tpv3Draft00MIB	1.3.6.1.4.1.99999.51			This MIB module complements the PW-STD-MIB module for PW operation over L2TPv3. Copyright (C) The Internet Society (2006). This version of this MIB module is part of RFC yyyy; see the RFC itself for full legal notices. -- RFC Ed.: replace yyyy with actual RFC number & remove -- this note
pwL2tpv3Notifications	1.3.6.1.4.1.99999.51.0
pwL2tpv3Objects	1.3.6.1.4.1.99999.51.1
pwL2tpv3Table	1.3.6.1.4.1.99999.51.1.1		not-accessible	This table controls L2TPv3 specific parameters when the PW is going to be carried over L2TPv3.
pwL2tpv3Entry	1.3.6.1.4.1.99999.51.1.1.1		not-accessible	A row in this table represents parameters specific to L2TPv3 for a pseudo wire (PW). A row MUST be created automatically by the local agent for every entry in the pwTable if the pwPsnType is l2tp. Each entry is indexed by pwIndex, which uniquely identifies a singular PW. A row can also be created manually in this table.
NUM pwL2tpv3SessionCfgIfIndex	1.3.6.1.4.1.99999.51.1.1.1.1	InterfaceIndexOrZero	read-create	The interface index for the corresponding L2TP interface to which this PW session is associated. The value of this object must correspond to the value of l2tpv3SessionCfgIfIndex in the l2tpv3SessionCfgTable.
STR pwL2tpv3CtrlCfgRouterID	1.3.6.1.4.1.99999.51.1.1.1.2	SnmpAdminString	read-create	The local router ID of this peer, as communicated via the Router ID AVP for this control connection. The value of this object corresponds to the value of l2tpv3CtrlCfgRouterID in l2tpv3CtrlCfgTable.
U32 pwL2tpv3LocalSessionID	1.3.6.1.4.1.99999.51.1.1.1.3	Unsigned32	read-create	The local L2TPv3 session id for this PW. The value of this object corresponds to the l2tpv3SessionCfgLocalID in l2tpv3SessionCfgTable.
U32 pwL2tpv3RemoteSessionID	1.3.6.1.4.1.99999.51.1.1.1.4	Unsigned32	read-create	The remote L2TPv3 session id for this PW. The value of this object corresponds to the l2tpv3SessionCfgRemoteID in l2tpv3SessionCfgTable.
BIT pwL2tpv3OperType	1.3.6.1.4.1.99999.51.1.1.1.5	Bits	read-create	Set by the operator to indicate the operation type of this PW.
INT pwL2tpv3DataSequencing	1.3.6.1.4.1.99999.51.1.1.1.6	INTEGER	read-create	Set by the operator to indicate data sequencing. noSeq(0) - No incoming data packets require sequencing. nonIpSeq(0)- Only non-IP data packets require sequencing. allSeq(2) - All incoming data packets require sequencing.
INT pwL2tpv3AddrResol	1.3.6.1.4.1.99999.51.1.1.1.7	INTEGER	read-create	The value of this object indicates the point-to-point address resolution mechanism for this PW.
U32 pwL2tpv3Mtu	1.3.6.1.4.1.99999.51.1.1.1.8	Unsigned32	read-create	Set by the operator to indicate the PW MTU value to be used on the PW.
STO pwL2tpv3StorageType	1.3.6.1.4.1.99999.51.1.1.1.9	StorageType	read-create	This variable indicates the storage type for this row. Conceptual rows having the value 'permanent' need not allow write-access to any columnar objects in the row.
ROW pwL2tpv3RowStatus	1.3.6.1.4.1.99999.51.1.1.1.10	RowStatus	read-create	This variable is used to create, modify, and/or delete a row in this table. When a row in this table is in active(1) state, no objects in that row can be modified by the agent except pwL2tpv3RowStatus and pwL2tpv3StorageType.
