3.11.2.4 TACACS+ Server

TACACS+ (Terminal Access Controller Access-Control System Plus) provides access control for routers,
network access servers (NAS) and other networked computing devices. The system implements the TACACS+
client and provides authentication functionality.
TACACS+ uses TCP port 49 by default. You can configure it according to your TACACS+ server. The Delta
switch supports multi TACACS+ servers' configuration and the number is up to 5.

3.11.2.5 TACACS+ AS

If you do not specify a TACACS+ AS (TACACS+ Active Service), the switch uses one of the TACACS+ servers
that you specify on the TACACS+ Server Configuration page. If you specify a TACACS+ Active Server (AS), the
switch uses only that server as the active TACACS+ server. So you can only specify one active server on this
page.
