Chapter 2 Cisco Catalyst Blade Switch 3020 for HP Cisco IOS Commands dot1x dot1x Use the dot1x global configuration command to globally enable IEEE 802.1x authentication. Use the no form of this command to return to the default setting. dot1x {critical {eapol | recovery delay milliseconds} | system-auth-control} no dot1x {credentials | critical {eapol | recovery delay} | system-auth-control} Note Though visible in the command-line help strings, the credentials name keywords are not supported. Syntax Description critical {eapol | recovery delay milliseconds} system-auth-control Configure the inaccessible authentication bypass parameters. For more information, see the dot1x critical (global configuration) command. Enable IEEE 802.1x authentication globally on the switch. Defaults IEEE 802.1x authentication is disabled. Command Modes Global configuration Command History Release 12.2(25)SEF Modification This command was introduced. Usage Guidelines You must enable authentication, authorization, and accounting (AAA) and specify the authentication method list before globally enabling IEEE 802.1x authentication. A method list describes the sequence and authentication methods to be used to authenticate a user. Before globally enabling IEEE 802.1x authentication on a switch, remove the EtherChannel configuration from the interfaces on which IEEE 802.1x authentication and EtherChannel are configured. If you are using a device running the Cisco Access Control Server (ACS) application for IEEE 802.1x authentication with EAP-Transparent LAN Services (TLS) and with EAP-MD5, make sure that the device is running ACS Version 3.2.1 or later. Examples This example shows how to globally enable IEEE 802.1x authentication on a switch: Switch(config)# dot1x system-auth-control You can verify your settings by entering the show dot1x [interface interface-id] privileged EXEC command.
