Abstract​

This document defines a Terminal Access Controller Access-Control System Plus (TACACS+) client YANG module that augments the System Management data model defined in RFC 7317. The module allows devices to use TACACS+ servers for centralized Authentication, Authorization, and Accounting (AAA), and can be used to manage TACACS+ over TLS.

This document obsoletes RFC 9105.
