               A YANG Data Model for Flex Ethernet(FlexE)
                     draft-xiaobn-flexe-yang-mod-00

Abstract

   Flex Ethernet(FlexE) implementation agreement have been published by
   OIF.  FlexE provides a generic mechanism for supporting a variety of
   Ethernet MAC rates that may or may not correspond to any existing
   Ethernet PHY rate.

   This document describes a YANG data model for FlexE.  It can be used
   to manage and control devices supporting FlexE functions.

1.  Introduction

   Flex Ethernet (FlexE) implementation agreement version 1.0
   [OIFFLEXE1] and 2.0 [OIFFLEXE2] have been published by OIF.  FlexE
   provides a generic mechanism for supporting a variety of Ethernet MAC
   rates that may or may not correspond to any existing Ethernet PHY
   rate.  This includes MAC rates that are both greater than (through
   bonding) and less than (through sub-rate and channelization) the
   Ethernet PHY rates used to carry FlexE.

   This document defines a date model of FlexE, using YANG[RFC7950].
   This model mainly deals with the data model of the FlexE Group and
   the FlexE client.  It can be used by an application to configure and
   modify the parameters of the FlexE Group and the FlexE client, and to
   receive notifications, e.g. mismatch errors, from devices supporting
   FlexE functions.

   Requirements for the FlexE YANG model are considered.  And FlexE YANG
   tree and YANG files are given.

2.  Terminology

   A simplified graphical representation of the data model is used in
   this document.  The meaning of the symbols in the YANG data tree
   presented later in this document is defined in [RFC8340].  They are
