802.1x Commands aaa authentication dot1x The aaa authentication dot1x Global Configuration mode command specifies one or more authentication, authorization, and accounting (AAA) methods for use to authenticate interfaces running IEEE 802.1X. Use the no form of this command to return to default. Syntax aaa authentication dot1x default method1 [method2...] no aaa authentication dot1x default • method1 [method2...]-At least one from the following table: Keyword Radius None Description Uses the list of all RADIUS servers for authentication Uses no authentication Default Configuration The default behavior of the "aaa authentication" for dot1.x is "failed to authenticate". If the 8021.x calls the AAA for authentication services it will receive a fail status. Command Mode Global configuration mode User Guidelines • The additional methods of authentication are used only if the previous method returns an error, for example the authentication server is down, and not if the request for authenticate is denied access. To ensure that the authentication succeeds even if all methods return an error, specify none as the final method in the command line. • The radius server must support MD-5 challenge and EAP type frames. Examples The following example uses the aaa authentication dot1x default command with no authentication. Console (config)# aaa authentication dot1x default none 802.1x Commands 371
