  Yang data model for Terminal Access Controller Access Control System

Abstract

   This document defines two YANG modules that augment the System data
   model defined in the [RFC 7317] with TACACS+ client model and
   additional AAA 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
   Accouting.  While the current system model only supports
   authentication configuration, the additional AAA model allows system
   authorization and accouting configuration.

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

1.  Introduction

   This document defines two YANG modules that augment the System data
   model defined in the [RFC 7317] with TACACS+ client model and
   additional AAA 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
   Accouting.  While the current system model only supports
   authentication configuration, the additional AAA model allows system
   authorization and accouting configuration.

   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.

   A YANG Data Model for System Management [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.
