IMPORTANT:
If is enabled, you must login using 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 (
telnet
) or secure backdoor (
secbd
) are
disabled.
If Telnet backdoor is enabled (
telnet ena
), type in
notacacs
as a backdoor to bypass
checking, and use the administrator password to log into the switch. The switch allows this even if
servers are available.
If secure backdoor is enabled (
secbd ena
), type in
notacacs
as a backdoor to bypass checking,
and use the administrator password to log into the switch. The switch allows this only if servers are
not available.
