dot1x host-mode

hosts on an IEEE
802.1x-authorized port. Use the no form of this command to return to the default
setting.

Command History
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 gigabitethernet1/1
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.
Related Commands
