Establishing TACACS+ Authentication and Authorization
Terminal Access Controller Access Control System (TACACS) is an authentication protocol that
provides remote access authentication, authorization, and related services such as event logging. With
TACACS, user passwords and privileges are administered in a central database instead of an individual
switch or router to provide scalability.
TACACS+ is a Cisco Systems enhancement that provides additional support for authentication and
authorization.
When a user logs into the NAM Traffic Analyzer, TACACS+ determines if the username and password
are valid and what the access privileges are.
To establish TACACS+ authentication and authorization:
Step 1 Choose Administration > Users > TACACS+. The TACACS+ Authentication and Authorization Dialog
Box displays.
Step 2 Enter or select the appropriate information in the TACACS+ Authentication and Authorization Dialog
Box (Table 5-10).
