Access Authentication Control
The TACACS/XTACACS/TACACS+/RADIUS commands let you secure access to the Switch using the
TACACS/XTACACS/TACACS+/RADIUS protocols. When a user logs in to the Switch or tries to access the
administrator level privilege, he or she is prompted for a password. If TACACS/XTACACS/TACACS+/RADIUS
authentication is enabled on the Switch, it will contact a TACACS/XTACACS/TACACS+/RADIUS server to verify the
user. If the user is verified, he or she is granted access to the Switch.
There are currently three versions of the TACACS security protocol, each a separate entity. The Switch's software supports
the following versions of TACACS:
TACACS (Terminal Access Controller Access Control System) – Provides password checking and
authentication, and notification of user actions for security purposes utilizing via one or more centralized
TACACS servers, utilizing the UDP protocol for packet transmission.
•
•
•
Extended TACACS (XTACACS) – An extension of the TACACS protocol with the ability to provide more
types of authentication requests and more types of response codes than TACACS. This protocol also uses UDP
to transmit packets.
TACACS+ (Terminal Access Controller Access Control System plus) – Provides detailed access control for
authentication for network devices. TACACS+ is facilitated through Authentication commands via one or more
centralized servers. The TACACS+ protocol encrypts all traffic between the Switch and the TACACS+ daemon,
using the TCP protocol to ensure reliable delivery
