The aaa authentication login "rad" radius command creates a login
•
authentication list called "rad" that contains the method radius. If this
method returns an error, the user will fail to login.
The aaa authentication enable "raden" radius command creates an
•
enable authentication list called "raden" that contains the method radius.
If this method fails, then the user will fail to execute the enable command.
• The radius-server host 1.2.3.4 command is the first step in defining a
RADIUS server at IP address 1.2.3.4. The result of this command is to
place the user in radius-server mode to allow further configuration of the
server.
• The key "secret" command defines the shared secret. This must be the
same as the shared secret defined on the RADIUS server.
• The line telnet command enters the configuration mode for the Telnet
line.
• The login authentication rad command assigns the rad login
authentication method list to be used for users accessing the switch via
Telnet.
• The enable authentication raden command assigns the raden enable
authentication method list to be used for users executing the enable
command when accessing the switch via Telnet.
