A YANG Data Model for Terminal Access Controller Access-Control System Plus
RFC 9950, “A YANG Data Model for Terminal Access Controller Access-Control System Plus”, is a Proposed Standard document published in March 2026 by M. Boucadair, B. Wu. It obsoletes RFC 9105. The canonical text is published by the RFC Editor.
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, to allow devices to make use of TACACS+ servers for centralized Authentication, Authorization, and Accounting (AAA). Specifically, the TACACS+ YANG module can be used to manage TACACS+ over TLS.
This document obsoletes RFC 9105.
What “Proposed Standard” means
An entry-level standards-track specification: stable, peer-reviewed and a solid basis for implementation, though it may still evolve before becoming an Internet Standard.
