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]. Kun/Alex/Chin/Hua Expires September 29, 2017 [Page 2] Internet-Draft CFM Yang Data Model March 2017 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. module: ietf-cfm +--ro dot1agCfmStack | +--ro dot1agCfmStackEntry* [dot1agCfmStackifIndex dot1agCfmStackVlanIdOrNone dot1agCfmStackMdLevel dot1agCfmStackDirection] | +--ro dot1agCfmStackifIndex cfm:if-index | +--ro dot1agCfmStackVlanIdOrNone cfm:VlanIdOrNone | +--ro dot1agCfmStackMdLevel cfm:Dot1agCfmMDLevel | +--ro dot1agCfmStackDirection cfm:Dot1agCfmMpDirection | +--ro dot1agCfmStackMdIndex?
