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.
