TACACS+ Overview
TACACS+ is a security application that provides centralized validation of users attempting to gain access to
your switch.
TACACS+ provides for separate and modular authentication, authorization, and accounting facilities. TACACS+
allows for a single access control server (the TACACS+ daemon) to provide each service—authentication,
authorization, and accounting—independently. Each service can be tied into its own database to take advantage
of other services available on that server or on the network, depending on the capabilities of the daemon.
