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
(bckdoor) or secure backdoor (secbd) are disabled.
If Telnet backdoor is enabled (bckdoor ena), type 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 (secbd ena), type in notacacs as a backdoor to bypass

this only if TACACS+ servers are not available.
