Dot1X Host-Mode - Cisco Catalyst Blade Switch 3130 Reference Manual

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.
Syntax Description
multi-host
single-host
Defaults The default is single-host mode.
Command Modes
Interface configuration
Command History Release
12.2(40)EX1
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.
