               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 configuration data and state data (status
   information and counters for the collection of statistics).

1.  Introduction

   This document defines a YANG [RFC6020] 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.

   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.

   The data model includes configuration data and state data (status
   information and counters for the collection of statistics).
