Configuring the switch

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+
servers are not available.
