Cisco Systems NAM, 5 Establishing TACACS+ Authentication and Authorization, Field Usage Notes

Chapter 5 User and System Administration

User Administration

Step 2 Select the username.

Step 3 Click Delete.

Note If you delete user accounts while users are logged in, they remain logged in and retain their privileges. The session remains in effect until they log out. Deleting an account or changing permissions in mid-session affects only future sessions. To force off a user who is logged in, restart the NAM.

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).
