Usage Guidelines The method argument identifies the method that the authentication algorithm tries in the given sequence
to validate the password provided by the client. The only method that is truly IEEE 802.1x-compliant is
the group radius method, in which the client data is validated against a RADIUS authentication server.
If you specify group radius, you must configure the RADIUS server by entering the radius-server host
global configuration command.
Use the show running-config privileged EXEC command to display the configured lists of
authentication methods.
