dot1x host-mode

dot1x host-mode

Use the dot1x host-mode interface configuration command on the switch stack or on a standalone switch
to allow a single host (client) or multiple hosts on an IEEE 802.1x-authorized port that has the dot1x
port-control
interface configuration command set to auto. Use the no form of this command to return
to the default setting.

Usage Guidelines

Use this command to limit an IEEE 802.1x-enabled port to a single client or to attach multiple clients to
an IEEE 802.1x-enabled port. In multiple-hosts mode, only one of the attached hosts needs to be
successfully authorized for all hosts to be granted network access. If the port becomes unauthorized
(re-authentication fails or an Extensible Authentication Protocol over LAN [EAPOL]-logoff message is
received), all attached clients are denied access to the network.

Before entering this command, make sure that the dot1x port-control interface configuration command
is set to auto for the specified port.

Examples

This example shows how to enable IEEE 802.1x authentication globally, to enable IEEE 802.1x
authentication on a port, and to enable multiple-hosts mode:

Switch(config)# dot1x system-auth-control

Switch(config)# interface gigabitethernet2/0/1

Switch(config-if)# dot1x port-control auto

Switch(config-if)# dot1x host-mode multi-host

You can verify your settings by entering the show dot1x [interface interface-id] privileged EXEC
command.
