Common Interface Extension YANG Data Models
draft-ietf-netmod-intf-ext-yang-01
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.
