              Common Interface Extension YANG Data Models
                   draft-ietf-netmod-intf-ext-yang-06

Abstract

   This document defines two YANG modules that augment the Interfaces
   data model defined in the "YANG Data Model for Interface Management"
   with additional configuration and operational data nodes to support
   common lower layer interface properties, such as interface MTU.
   These properties are common to many types of interfaces on network
   routers and switches and are implemented by multiple network
   equipment vendors with similar semantics, even though some of the
   features are not formally defined in any published standard.
