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.

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.

aaa authentication dot1x {default} method1

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