RFC 7697 MPLS-TP OAM ID MIB January 2016
1. Introduction
This memo defines a portion of the Management Information Base (MIB)
for use with network management protocols in the Internet community.
In particular, it describes managed objects for modeling a Transport
Profile (TP) based on Multiprotocol Label Switching (MPLS) [RFC3031].
This MIB module should be used for performing the OAM (Operations,
Administration, and Maintenance) operations for MPLS Tunnel LSPs
(Label Switched Paths), Pseudowires, and Sections.
At the time of this writing, SNMP SET is no longer recommended as a
way to configure MPLS networks as was described in [RFC3812].
However, since the MIB modules specified in this document are
intended to work in parallel with the MIB modules for MPLS specified
in [RFC3812], certain objects defined here are specified with a
MAX-ACCESS of read-write or read-create so that specifications of the
base tables in [RFC3812] and the new MIB modules in this document are
consistent. Although the example described in Section 6 specifies
means to configure OAM identifiers for MPLS-TP Tunnels, this should
be seen as indicating how the MIB values would be returned in the
specified circumstances having been configured by alternative means.
2. The Internet-Standard Management Framework
For a detailed overview of the documents that describe the current
Internet-Standard Management Framework, please refer to section 7 of
RFC3410 [RFC3410].
Managed objects are accessed via a virtual information store, termed
the Management Information Base or MIB. MIB objects are generally
accessed through the Simple Network Management Protocol (SNMP).
Objects in the MIB are defined using the mechanisms defined in the
Structure of Management Information (SMI). This memo specifies a MIB
module that is compliant to the SMIv2, which is described in STD 58,
RFC 2578 [RFC2578], STD 58, RFC 2579 [RFC2579] and STD 58, RFC 2580
[RFC2580].

RFC 7697 MPLS-TP OAM ID MIB January 2016
4. Feature List
The MPLS transport profile OAM identifiers MIB module is designed to
satisfy the following requirements and constraints:
- The MIB module supports configuration of OAM identifiers for MPLS
point-to-point Tunnels, point-to-multipoint LSPs, co-routed
bidirectional LSPs, associated bidirectional LSPs, and
Pseudowires.
5. Brief Description of MIB Objects
The objects described in this section support the functionality
described in [RFC5654] and [RFC6370]. The tables support both
IP-compatible and ICC-based OAM identifiers configurations for MPLS
Tunnels, LSPs, and Pseudowires.
5.1. mplsOamIdMegTable
The mplsOamIdMegTable is used to manage one or more Maintenance
Entities (MEs) that belong to the same transport path.
When a new entry is created with mplsOamIdMegOperatorType set to
ipCompatible (1), then as per [RFC6370] (MEG_ID for an LSP is LSP_ID,
and MEG_ID for a PW is PW_Path_ID), MEP_ID can be automatically
formed.
For an ICC-based transport path, the user is expected to configure
the ICC identifier explicitly in this table for MPLS Tunnels, LSPs,
and Pseudowires.
5.2. mplsOamIdMeTable
The mplsOamIdMeTable defines a relationship between two points
(source and sink) of a transport path to which maintenance and
monitoring operations apply. The two points that define an ME are
called Maintenance Entity Group End Points (MEPs).
In between MEPs, there are zero or more intermediate points, called
Maintenance Entity Group Intermediate Points (MIPs). MEPs and MIPs
are associated with the MEG and can be shared by more than one ME in
a MEG.
Aldrin, et al. Standards Track [Page 5]
RFC 7697 MPLS-TP OAM ID MIB January 2016
6. MPLS OAM Identifier Configuration for MPLS LSP: Example
In this section, we provide an example of the OAM identifier
configuration for an MPLS co-routed bidirectional LSP.
This example provides usage of MEG and ME tables for management and
monitoring operations of an MPLS LSP.
This example considers the OAM identifiers configuration on a
head-end LSR to manage and monitor an MPLS LSP. Only relevant
objects that are applicable for IP-based OAM identifiers of MPLS
co-routed bidirectional LSPs are illustrated here.
In the mplsOamIdMegTable:
{
-- MEG index (Index to the table)
mplsOamIdMegIndex = 1,
mplsOamIdMegName = "MEG1",
mplsOamIdMegOperatorType = ipCompatible (1),
mplsOamIdMegServicePointerType = lsp (1),
mplsOamIdMegMpLocation = perNode (1),
-- Mandatory parameters needed to activate the row go here
mplsOamIdMegRowStatus = createAndGo (4),
mplsOamIdMegPathFlow
= coRoutedBidirectionalPointToPoint (2)
}
This will create an entry in the mplsOamIdMegTable to manage and
monitor the MPLS Tunnel.
Aldrin, et al. Standards Track [Page 6]
RFC 7697 MPLS-TP OAM ID MIB January 2016
The following ME table is used to associate the path information
to a MEG.
In the mplsOamIdMeTable:
{
-- ME index (Index to the table)
mplsOamIdMeIndex = 1,
-- MP index (Index to the table)
mplsOamIdMeMpIndex = 1,
mplsOamIdMeName = "ME1",
mplsOamIdMeMpIfIndex = 0,
-- The source MEP ID is derived from the IP-compatible MPLS LSP
mplsOamIdMeSourceMepIndex = 0,
-- The sink MEP ID is derived from the IP-compatible MPLS LSP
mplsOamIdMeSinkMepIndex = 0,
mplsOamIdMeMpType = mep (1),
mplsOamIdMeMepDirection = down (2),
-- RowPointer MUST point to the first accessible column of an
-- MPLS LSP
mplsOamIdMeServicePointer = mplsTunnelName.1.1.10.20,
-- Mandatory parameters needed to activate the row go here
mplsOamIdMeRowStatus = createAndGo (4)
}

Z9-{Global_ID::Node_ID::Tunnel_Num::LSP_Num}.
For an LSP, MEP_ID is formed using
Global_ID::Node_ID::Tunnel_Num::LSP_Num.
For a PW, MEG_ID is formed using AGI::
A1-{Global_ID::Node_ID::AC_ID}::
Z9-{Global_ID::Node_ID::AC_ID}.
For a PW, MEP_ID is formed using
AGI::Global_ID::Node_ID::AC_ID.
MEP_ID is retrieved from the mplsOamIdMegServicePointer
object based on the mplsOamIdMegServicePointerType value.
The ICC MEG_ID for an LSP and a PW is formed using the

DESCRIPTION
"An entry in this table represents an MPLS-TP ME. This
entry represents the ME if the source and sink MEPs are
defined.
An ME is a point-to-point entity. One ME has two such
MEPs. A MEG is a group of one or more MEs. One MEG can
have two or more MEPs.
For a point-to-point LSP, one MEG has one ME, and this ME
is associated with two MEPs (source and sink MEPs) within
a MEG. Each mplsOamIdMeIndex value denotes the ME within
a MEG.
Aldrin, et al. Standards Track [Page 19]
RFC 7697 MPLS-TP OAM ID MIB January 2016
In the case of unidirectional point-to-point transport
paths, a single unidirectional ME is defined to monitor
it, and mplsOamIdMeServicePointer points to a
unidirectional point-to-point path.
In the case of associated bidirectional point-to-point
transport paths, two independent unidirectional
MEs are defined to independently monitor each direction,
and each mplsOamIdMeServicePointer MIB object points to a
unique unidirectional transport path.
This has implications for transactions that terminate at
or query a MIP, as a return path from a MIP to a source
MEP does not necessarily exist within the MEG.
In the case of co-routed bidirectional point-to-point
transport paths, a single bidirectional ME is defined to
monitor both directions congruently, and the
mplsOamIdMeServicePointer MIB object points to a co-routed
bidirectional point-to-point transport path.
In the case of unidirectional point-to-multipoint transport
paths, a single unidirectional ME for each leaf is defined
to monitor the transport path from the root to that leaf,
and each leaf has different transport path information in
the mplsOamIdMeServicePointer MIB object. Note that the
MplsOamIdMeEntry should be created manually once the MEG
is configured for OAM operations."

8. Security Considerations
This MIB relates to a system that will provide network connectivity
and packet forwarding services. As such, improper manipulation of
the objects represented by this MIB may result in denial of service
to a large number of end-users.
There are a number of management objects defined in this MIB module
with a MAX-ACCESS clause of read-write and/or read-create. Such
objects may be considered sensitive or vulnerable in some network
environments. The support for SET operations in a non-secure
environment without proper protection opens devices to attack.
Some of the readable objects in this MIB module (i.e., objects with a
MAX-ACCESS other than not-accessible) may be considered sensitive or
vulnerable in some network environments. It is thus important to
control even GET and/or NOTIFY access to these objects and possibly
to even encrypt the values of these objects when sending them over
the network via SNMP. These are the tables and objects and their
sensitivity/vulnerability:
- The mplsOamIdMegTable and the mplsOamIdMeTable collectively show
the MPLS OAM characteristics. If an administrator does not want to
reveal this information, then these tables should be considered
sensitive/vulnerable.
SNMP versions prior to SNMPv3 did not include adequate security.
Even if the network itself is secure (for example by using IPsec),
there is no control as to who on the secure network is allowed to
access and GET/SET (read/change/create/delete) the objects in this
MIB module.
Implementations SHOULD provide the security features described by the
SNMPv3 framework (see [RFC3410]), and implementations claiming
compliance to the SNMPv3 standard MUST include full support for
authentication and privacy via the User-based Security Model (USM)
[RFC3414] with the AES cipher algorithm [RFC3826]. Implementations
MAY also provide support for the Transport Security Model (TSM)
[RFC5591] in combination with a secure transport such as SSH
[RFC5592] or TLS/DTLS [RFC6353].
Further, deployment of SNMP versions prior to SNMPv3 is NOT
RECOMMENDED. Instead, it is RECOMMENDED to deploy SNMPv3 and to
enable cryptographic security. It is then a customer/operator
responsibility to ensure that the SNMP entity giving access to an
instance of this MIB module is properly configured to give access to
the objects only to those principals (users) that have legitimate
rights to indeed GET or SET (change/create/delete) them.

9. IANA Considerations
As described in [RFC4221] and [RFC6639], and as requested in the
MPLS-TC-STD-MIB [RFC3811], MPLS-related Standards Track MIB modules
should be rooted under the mplsStdMIB subtree. The following
subsection lists a new assignment that has been made by IANA under
the mplsStdMIB subtree for the MPLS-OAM-ID-STD-MIB module defined in
this document. New assignments can only be made via a Standards
Action as specified in [RFC5226].
9.1. IANA Considerations for MPLS-OAM-ID-STD-MIB
IANA has to assign the OID { mplsStdMIB 21 } to the
MPLS-OAM-ID-STD-MIB module specified in this document.
