Command History
Usage Guidelines Single-host mode should be configured if only one data host is connected. Do not connect a voice device
to authenticate on a single-host port. Voice device authorization fails if no voice VLAN is configured on
the port.
Multi-domain mode should be configured if data host is connected through an IP Phone to the port.
Multi-domain mode should be configured if the voice device needs to be authenticated.
Multi-auth mode should be configured to allow devices behind a hub to obtain secured port access
through individual authentication. Only one voice device can be authenticated in this mode if a voice
VLAN is configured.
Multi-host mode also offers port access for multiple hosts behind a hub, but multi-host mode gives
unrestricted port access to the devices after the first user gets authenticated.
Examples This example shows how to enable multiauth mode on a port:
Switch(config-if)# authentication host-mode multi-auth
This example shows how to enable multi-domain mode on a port:
