Tacacs+ User Mappings Configuration
Maps a TACACS+ privilege level to this switch user level, as follows:
Remote Privilege
Enter a TACACS+ privilege level (0-15)
Local Privilege
Select the corresponding this switch user level.
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
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 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 noradius 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.
