                   draft-wu-netmod-factory-default-03

Abstract

   This document defines a method to reset a YANG server to its factory-
   default content.  The reset operation may be used e.g. during initial
   zero-touch configuration or when the existing configuration has major
   errors, so re-starting the configuration process from scratch is the
   best option.

   A new factory-reset RPC is defined.  Several methods of documenting
   the factory-default content are specified.

   Optionally a new "factory-default" read-only datastore is defined,
   that contains the data that will be copied over to the running
   datastore at reset.

1.  Introduction

   This document defines a method to reset a YANG server to its factory-
   default content.  The reset operation may be used e.g. during initial
   zero-touch configuration or when the existing configuration has major
   errors, so re-starting the configuration process from scratch is the
   best option.  When resetting a datastore all previous configuration
   settings will be lost and replaced by the factory-default content.

   A new factory-reset RPC is defined.  Several methods of documenting
   the factory-default content are specified.

   Optionally a new "factory-default" read-only datastore is defined,
   that contains the data that will be copied over to the
   <startup>,<candiate>,<running> datastore at reset.  This datastore
   can also be used in <get-data> or <copy-config> operations.
