RADIUS Authentication Example Use the following configuration to require RADIUS authentication to login over a telnet connection: aaa authentication login "rad" radius aaa authentication enable "raden" radius radius-server host 1.2.3.4 key "secret" exit line telnet login authentication rad enable authentication raden exit The following describes each line in the above configuration: • 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. 188 Configuring Authentication, Authorization, and Accounting
