Detailed explanation-1: -The two most popular AAA protocols for external AAA services commonly implemented in today’s networks are RADIUS and TACACS+, and both use a client-server model.
Detailed explanation-2: -Authentication, authorization, and accounting (AAA) is a term for a framework for intelligently controlling access to computer resources, enforcing policies, auditing usage, and providing the information necessary to bill for services.
Detailed explanation-3: -After the administrator accesses a network device via HTTPS, SSH or Telnet, the user credentials are forwarded to the AAA server using the TACACS+ protocol. After successful authentication, each user’s command must be authorized against the set of allowed commands. Cisco ISE can be used as a TACACS+ server.
