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.
Examples This example shows how to enable AAA and how to create an IEEE 802.1x-compliant authentication
list. This authentication first tries to contact a RADIUS server. If this action returns an error, the user is
not allowed access to the network.
Switch(config)# aaa new-model
Switch(config)# aaa authentication dot1x default group radius
You can verify your settings by entering the show running-config privileged EXEC command.
