TACACS+
Terminal Access Controller Access Control System (TACACS+) provides centralized security
user access validation. The system supports up-to 2 TACACS+ servers.
TACACS+ provides a centralized user management system, while still retaining consistency with
RADIUS and other authentication processes.
The TACACS+ protocol ensures network integrity through encrypted protocol exchanges between
the client and TACACS+ server. The user-assigned TACACS+ parameters are applied to newly
defined TACACS+ servers. If values are not defined, the system defaults are applied to the new
TACACS+ servers.
To configure TACACS+ Settings:
1. Click Security > Management Security > TACACS+. The TACACS+ screen displays:
