dot1x host-mode
dot1x host-mode
Use the dot1x host-mode interface configuration command 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 globally, to enable IEEE 802.1x on a port, and to enable 
multiple-hosts mode:
Switch(config)# dot1x system-auth-control
Switch(config)# interface gigabitethernet0/1
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.
