Add TACACS+ Servers (TACACS+ Authentication Method)

Security > TACACS+
Terminal Access Controller Access Control System (TACACS+) provides centralized
security user access validation. The system supports up-to 5 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.
1. Log into your switch management page (see
on page 7).
2. Click on Security and click on TACACS+.
3. Review the settings.

Server Priority – Enter the TACACS+ Server priority (Highest: 1, Lowest: 5).

