Radius Secret
Secondary Radius Server Secret
IMPORTANT: If RADIUS is enabled, you must login using RADIUS authentication when connecting
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 or secure backdoor
are disabled.
If Telnet backdoor is enabled, 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, 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.
