Dot1X Host-Mode - Cisco ME 3400 Command Reference Manual

Chapter 2 Cisco ME 3400 Ethernet Access Switch Cisco IOS Commands

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.
Although visible in the command-line interface help, the multi-domain keyword is not supported.
Note
Syntax Description

single-host
Defaults The default is single-host mode.
Command Modes Interface configuration
Command History Release
12.2(25)EX
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 must 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.
The dot1x host-mode multi-domain interface configuration command is not supported on the switch.
Configuring this command on an interface causes the interface to go into the error-disabled state.
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.
