Abstract

   This document defines a YANG modules that augment the System data
   model defined in the RFC 7317 with TACACS+ client model.  The data
   model of Terminal Access Controller Access Control System Plus
   (TACACS+) client allows the configuration of TACACS+ servers for
   centralized Authentication, Authorization and Accounting.

   The YANG modules in this document conforms to the Network Management
   Datastore Architecture (NMDA) defined in RFC 8342.

1.  Introduction

   This document defines a YANG modules that augment the System data
   model defined in the [RFC7317] with TACACS+ client model.

   TACACS+ provides Device Administration for routers, network access
   servers and other networked computing devices via one or more
   centralized servers which is defined inthe TACACS+ Protocol.
   [I-D.ietf-opsawg-tacacs]

   The System Management Model [RFC7317] defines two YANG features to
   support local or RADIUS authentication:

   o  User Authentication Model: Define a list of usernames and
      passwords and control the order in which local or RADIUS
      authentication is used.

   o  RADIUS Client Model: Defines a list of RADIUS server that a device
      used.

   Since TACACS+ is also used for device management and the feature is
   not contained in the system model, this document defines a YANG data
   model that allows users to configure TACACS+ client functions on a
   device for centralized Authentication, Authorization and Accounting
   provided by TACACS+ servers.

   The YANG models can be used with network management protocols such as
   NETCONF[RFC6241] to install, manipulate, and delete the configuration
   of network devices.

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