Using TACACS+ Servers to Control Management Access
TACACS+ (Terminal Access Controller Access Control System) provides
access control for networked devices via one or more centralized servers.
TACACS+ simplifies authentication by making use of a single database that
can be shared by many clients on a large network. TACACS+ uses TCP to
ensure reliable delivery and a shared key configured on the client and daemon
server to encrypt all messages.
If TACACS+ is configured as the authentication method for user login and a
user attempts to access the user interface on the switch, the switch prompts
for the user login credentials and requests services from the TACACS+
client. The client then uses the configured list of servers for authentication,
and provides results back to the switch.
