1. Overview
This document defines a YANG [RFC6020] data model which can be used
for configuring and managing CFM [IEEE802.1ag].
This data model includes configuration data and state data, for
example the configuration of MD, MA, and MEP and the state of MEP.
1.1. Requirement language
The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
"SHOULD", "SHOULD NOT", "RECOMMENDED", "NOT RECOMMENDED", "MAY", and
"OPTIONAL" in this document are to be interpreted as described in
[RFC2119].

2. Design of Data Model
The goal of this document is to define a data model that provides a
common user interface to the CFM. There is very little information
that is designated as "mandatory", providing freedom for vendors to
adapt this data model to their respective product implementations.
2.1. Overview
The CFM YANG module defined in this document has all the common
building blocks for the CFM protocol.
The CFM module is created based on CFM MIB with a slight change for
meeting the YANG model requirement.

"The RowStatus textual convention is used to manage the

value of the SYNTAX clause for the status column of a

The status column has six defined values:
- `active', which indicates that the conceptual row is
available for use by the managed device;
- `notInService', which indicates that the conceptual
row exists in the agent, but is unavailable for use by
the managed device; 'notInService' has no implication
regarding the internal consistency of the row,
availability of resources, or consistency with the
current state of the managed device;
- `notReady', which indicates that the conceptual row
exists in the agent, but is missing information
necessary in order to be available for use by the
managed device (i.e., one or more required columns in
the conceptual row have not been instanciated);
- `createAndGo', which is supplied by a management
station wishing to create a new instance of a

station wishing to create a new instance of a

the managed device); and,
- `destroy', which is supplied by a management station

an existing conceptual row.
Whereas five of the six values (all except `notReady') may
be specified in a management protocol set operation, only
three values will be returned in response to a management
protocol retrieval operation: `notReady', `notInService' or
`active'. That is, when queried, an existing conceptual row
has only three states: it is either available for use by
the managed device (the status column has value `active');
it is not available for use by the managed device, though

A Dot1agCfmMaintDomainName value is interpreted within
the context of a Dot1agCfmMaintDomainNameType value. Every
usage of the Dot1agCfmMaintDomainName textual convention is
required to specify the Dot1agCfmMaintDomainNameType object
that provides the context. It is suggested that the

before the object(s) that use the Dot1agCfmMaintDomainName
textual convention, if they appear in the same logical row.
The value of a Dot1agCfmMaintDomainName object must always
be consistent with the value of the associated
Dot1agCfmMaintDomainNameType object. Attempts to set
an Dot1agCfmMaintDomainName object to a value inconsistent
with the associated Dot1agCfmMaintDomainNameType must fail
with an inconsistentValue error.
When this textual convention is used as the syntax of an
index object, there may be issues with the limit of 128
sub-identifiers specified in SMIv2, IETF STD 58. In this
case, the object definition MUST include a 'SIZE' clause

Dot1agCfmMaintAssocNameType textual convention SHOULD NOT
be sub-typed in object type definitions. It MAY be
sub-typed in compliance statements in order to require
only a subset of these address types for a compliant

Implementations must ensure that Dot1agCfmMaintAssocNameType

Dot1agCfmMaintAssocName objects) are consistent. An
inconsistentValue error must be generated if an attempt to
change an Dot1agCfmMaintAssocNameType object would, for
example, lead to an undefined Dot1agCfmMaintAssocName value.
In particular,
Dot1agCfmMaintAssocNameType/Dot1agCfmMaintAssocName pairs
must be changed together if the nameType changes.

description
"A MEP has a persistent defect condition. A notification
(fault alarm) is sent to the management entity with the OID
of the MEP that has detected the fault.
Whenever a MEP has a persistent defect,
it may or may not generate a Fault Alarm to warn the system
administrator of the problem, as controlled by the MEP
Fault Notification Generator State Machine and associated
Managed Objects. Only the highest-priority defect, as shown
in Table 20-1, is reported in the Fault Alarm.
If a defect with a higher priority is raised after a Fault
Alarm has been issued, another Fault Alarm is issued.

identify the system from the network source address of the
notification, and can identify the MEP reporting the defect
by the indices in the OID of the dot1agCfmMepHighestPrDefect
