5.1.1.5 Dening TACACS+ Host Settings

Terminal Access Controller Access Control System (TACACS+) provides centralized security user access validation. The

system supports up-to 4 TACACS+ servers.

TACACS+ provides a centralized user management system, while still retaining consistency with RADIUS and other

authentication processes. TACACS+ provides the following services:

Authentication — Provides authentication during login and via user names and user-dened passwords.

Authorization — Performed at login. Once the authentication session is completed, an authorization session starts using

the authenticated user name.

The TACACS+ protocol ensures network integrity through encrypted protocol exchanges between the client and TACACS+

server.

Note:

The TACACS+ default parameters are user-assigned defaults. The default settings are applied to newly dened TACACS+

servers. If default values are not dened, the system defaults are applied to the new TACACS+ servers.

To dene TACACS+ authentication settings:

1. Click Security > Management Security > Authentication > TACACS+. The TACACS+ Page opens:

Figure 33: TACACS+ Page

The Default Parameters section contains the following

elds:

Source IP Address — Defines the default device

source IP address used for the TACACS+ session

between the device and the TACACS+ server.

Key String (1-128 Characters) — Defines the

authentication and encryption key for TACACS+

communications between the device and the TACACS+ server. This key must match the encryption used on the

TACACS+ server.

Timeout for Reply — Denes the default time that passes before the connection between the device and the TACACS+

times out. The default is 5.

The TACACS+ Page also contains the following elds:

Host IP Address — Denes the TACACS+ Server IP address.

Priority — Denes the order in which the TACACS+ servers are used. The eld range is 0-65535. The default is 0.

Source IP Address — Denes the device source IP address used for the TACACS+ session between the device and

the TACACS+ server.

Authentication Port (0-65535) — Denes the port number via which the TACACS+ session occurs. The default port is

port 49.
