               A YANG Data Model for Interface Management

Abstract

   This document defines a YANG data model for the management of network
   interfaces.  It is expected that interface-type-specific data models
   augment the generic interfaces data model defined in this document.
   The data model includes definitions for configuration and system
   state (status information and counters for the collection of
   statistics).

   The YANG data model in this document conforms to the Network
   Management Datastore Architecture (NMDA) defined in RFC 8342.

   This document obsoletes RFC 7223.

RFC 8343                YANG Interface Management             March 2018

1.  Introduction

   This document defines a YANG data model [RFC7950] for the management
   of network interfaces.  It is expected that interface-type-specific
   data models will augment the generic interfaces data model defined in
   this document.

   Network interfaces are central to the management of many Internet
   protocols.  Thus, it is important to establish a common data model
   for how interfaces are identified, configured, and monitored.
