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.

You can use the guest-vlan supplicant keywords to enable the optional IEEE 802.1x guest VLAN
behavior globally on the switch. For more information, see the

dot1x guest-vlan

command.

critical {eapol |
recovery delay
milliseconds}

Configure the inaccessible authentication bypass parameters. For more
information, see the

dot1x critical (global configuration)

command.

guest-vlan supplicant

Enable optional guest VLAN behavior globally on the switch.

system-auth-control
