IMPORTANT:
via the console or Telnet/SSH/HTTP/HTTPS. Backdoor for console is always enabled, so you can
connect using noradius and the administrator password even if the backdoor (telnet) or secure
backdoor (secbd) are disabled.
If Telnet backdoor is enabled (telnet ena), type in noradius as a backdoor to bypass RADIUS
checking, and use the administrator password to log into the switch. The switch allows this even if
RADIUS servers are available.
If secure backdoor is enabled (secbd ena), type in noradius as a backdoor to bypass RADIUS
checking, and use the administrator password to log into the switch. The switch allows this only if
RADIUS servers are not available.

TACACS+ (Terminal Access Controller Access Control System) is an authentication protocol that
allows a remote access server to forward a user's logon password to an authentication server to
determine whether access can be allowed to a given system. TACACS+ and Remote Authentication
Dial-In User Service (RADIUS) protocols are more secure than the TACACS encryption protocol.
TACACS+ is described in RFC 1492.
TACACS+ protocol is more reliable than RADIUS, as TACACS+ uses the Transmission Control
Protocol (TCP) whereas RADIUS uses the User Datagram Protocol (UDP). Also, RADIUS combines
authentication and authorization in a user profile, whereas TACACS+ separates the two operations.
If RADIUS is enabled, you must login using RADIUS authentication when connecting
