TACACS+ offers the following advantages over RADIUS as the authentication device:
TACACS+ is TCP-based, so it facilitates connection-oriented traffic.
It supports full-packet encryption, as opposed to password-only in authentication requests.
It supports decoupled authentication, authorization, and accounting.
The following table describes Switch TACACS+ Configuration controls:

IMPORTANT:
If TACACS+ is enabled, you must login using TACACS+ authentication when
connecting via the console or Telnet/SSH/HTTP/HTTPS. Backdoor for console is always enabled,
so you can connect using notacacs and the administrator password even if the backdoor or
secure backdoor are disabled.
If Telnet backdoor is enabled, type in notacacs as a backdoor to bypass TACACS+ checking,
and use the administrator password to log into the switch. The switch allows this even if TACACS+
servers are available.
If secure backdoor is enabled, type in notacacs as a backdoor to bypass TACACS+ checking,
and use the administrator password to log into the switch. The switch allows this only if TACACS+
