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.
