Access Authentication Control
The TACACS / XTACACS / TACACS+ / RADIUS commands allow users to 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.
