                  draft-ietf-netmod-factory-default-09

Abstract

   This document defines a method to reset a server to its factory-
   default content.  The reset operation may be used, e.g., 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.  When resetting a datastore, all
   previous configuration settings will be lost and replaced by the
   factory-default content.

   A new optional "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 server to its factory-
   default content.  The reset operation may be used, e.g., when the
   existing configuration has major errors so re-starting the
   configuration process from scratch is the best option.

   A factory-reset RPC is defined.  When resetting a datastore, all
   previous configuration settings will be lost and replaced by the
   factory-default content.

   A "factory-default" read-only datastore is defined, that contains the
   data to replace the contents of implemented read-write conventional
   configuration datastores at reset.  This datastore can also be used
   in <get-data> operation.

   NETCONF defines the <delete-config> RPC operation, but that only acts
   on the <startup-datastore>, whereas the <factory-reset> RPC operation
   can perform additional changes to the device to fully reset the
   device back to a factory-default state

   The YANG data model in this document conforms to the Network
   Management Datastore Architecture defined in [RFC8342].
