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 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.

aaa authentication dot1x {default} method1

no aaa authentication dot1x {default}

Use the listed authentication method that follows this argument as the default

method when a user logs in.

Enter the group radius keywords to use the list of all RADIUS servers for

authentication.
