YANG Data Model for MPLS-TP Operations, Administration, and Maintenance
(OAM)
draft-zhang-mpls-tp-yang-oam-02
Abstract
The Transport Profile of Multiprotocol Label Switching (MPLS-TP)
[RFC5921]is a packet-based transport technology based on the MPLS
Traffic Engineering (MPLS-TE) and pseudowire (PW) data-plane
architectures. A comprehensive set of Operations, Administration,
and Maintenance (OAM) procedures that fulfill the MPLS-TP OAM
requirements for fault, performance, and protection-switching
management had been defined. YANG [RFC6020]is a data definition
language that was introduced to define the contents of a conceptual
data store that allows networked devices to be managed using NETCONF
[RFC6241]. This document presents the YANG Data model for MPLS-TP
OAM, including the basic functions of Fault Management and
Performance Monitoring.
Requirements Language
The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
"SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this
document are to be interpreted as described in RFC 2119 [RFC2119].

architectures. A comprehensive set of Operations, Administration,
and Maintenance (OAM) procedures that fulfill the MPLS-TP OAM
requirements for fault, performance, and protection-switching
management had been defined. YANG [RFC6020] is a data definition
language that was introduced to define the contents of a conceptual
data store that allows networked devices to be managed using NETCONF
[RFC6241]. This document presents the YANG Data model for MPLS-TP
OAM, including the basic functions of Fault Management and
Performance Monitoring.
The rest of this document is organized as follows. Section 2
presents the conventions used in this document. Section 3 provides
the design of the MPLS-TP OAM data model in details. Section 4
presents the complete data hierarchy of LSP-Ping YANG model.
Section 5 discusses the interaction between MPLS-TP OAM data model
and other MPLS tools data models. Section 6 specifies the YANG
module and section 7 lists examples which conform to the YANG module
specified in this document. Finally, security considerations are
discussed in Section 8.

3. Design of the Data Model
This YANG data model is defined to be used to configure and manage
MPLS-TP OAM. Under the top level container mplstp-oam is the
container meg, which contains the configuration and detect result
information of multi instances of Maintenance Entity Group (MEG).
Under meg container, configuration of each Maintenance Entity (ME)
type are defined in corresponding list for a particular MEG.
Different OAM function cofiguration are also defined for each MEG.
The ME status and detect result information is also shown on per MEG
basis. In order to facilitate zero-touch experience, this document
defines a default value of the related detect parameters, such as
detection intervals, the exp of OAM packet and OAM packet size.
3.1. Maintenance Entity Group (MEG) Configuration
The container "meg" holds the configuration and detect result
information of multi instances of Maintenance Entity Group (MEG).
Each MEG is indexed by meg-name. The data hierarchy for MEG
configuration is presented below:
module: ietf-mplstpoam
+--rw mplstp-oam
+--rw ais-enable? enable
+--rw meg* [meg-name]
+--rw meg-name string
+--rw me-type? me-type
+--rw meg-id? string
+--rw meg-level? uint8
+--rw oam-active-state? active-type
3.2. Maintenance Entities (MEs) Configuration
Within a given Maintenance Entity Group there could be one or more
type of Maintenance Entity (ME), cofiguration of different types of
MEs are represented in its corresponding list and indexed by its own
key.The data hierarchy for ME configuration is presented below:
module: ietf-mplstpoam
+--rw mplstp-oam
+--rw ais-enable? enable
+--rw meg* [meg-name]
+--rw meg-name string
+--rw me-type? me-type
+--rw meg-id? string
+--rw meg-level? uint8

7. Examples
Examples of using Yang module to configure and manage MPLS-TP OAM
will be given here in the update.
8. Security Considerations
The configuration and state data defined in this document is designed
to be accessed via the NETCONF protocol [RFC6241]. The lowest
NETCONF layer is the secure transport layer and the mandatory-to-
implement secure transport is SSH [RFC6242]. The authors recommend
to implement the NETCONF access control model [RFC6536] to restrict
access for particular NETCONF users to a pre-configured subset of all
available NETCONF protocol operations and content. There are a
number of config true nodes defined in the YANG module which are
writable/creatable/deletable. These data nodes may be considered
Zhang, et al. Expires August 27, 2016 [Page 47]
Internet-Draft MPLS-TP OAM Yang February 2016
sensitive or vulnerable in some network environments. Write
operations to these data nodes without proper protection can have a
negative effect on network operations.
9. IANA Considerations
The IANA is requested to as assign a new namespace URI from the IETF
XML registry.
