RFC 5607 RADIUS NAS-Management Authorization July 2009
1. Introduction
RFC 2865 [RFC2865] defines the NAS-Prompt (7) and Administrative (6)

(CLI) of the NAS, and were originally developed to control access to
the physical console port of the NAS, most often a serial port.
Remote access to the CLI of the NAS has been available in NAS
implementations for many years, using protocols such as Telnet,
