authentication host-mode {multi-host | multi-auth [vlan VLAN-ID [, | -]]}
no authentication host-mode [multi-auth vlan VLAN-ID [, | -]]
Parameters
multi-host
multi-auth
vlan VLAN-ID
Default
By default, multi-auth is used.
Command Mode
Interface Configuration Mode.
Command Default Level
Level: 12.
Usage Guideline
If the port is operated in the multi-host mode, and if one of the hosts is authenticated, then all other
hosts are allowed to access the port. According to 802.1X authentication, if the re-authentication fails
or the authenticated user logs off, the port will be blocked for a quiet period. The port restores the
processing of EAPOL packets after the quiet period.
If the port is operated in the multi-auth mode, then each host needs to be authenticated individually
to access the port. A host is represented by its MAC address. Only the authorized host is allowed to
access.
Example
This example shows how to specify the Ethernet port 1/0/1 to operate in the multi-host mode.
Switch# configure terminal
Switch(config)# interface eth 1/0/1
Switch(config-if)# authentication host-mode multi-host
Switch(config-if)#
30-3
This command is used to enable periodic re-authentication for a port. Use the no form of this
command to disable periodic re-authentication.

Specifies the port to operate in the multi-host mode. Only a single
authentication is performed and all hosts connected to the port are
allowed.
Specifies the port to operate in the multi-auth mode.Each host will be
authenticated individually.
(Optional) Specifies the authentication VLAN(s). This is useful when
different VLANs on the Switch have different authentication
requirements. Using the no command, all the VLANs are removed If
not specified. This means that it does not care which VLAN the client
comes from, the client will be authenticated if the client's MAC address
(regardless of the VLAN) is not authenticated. After the client is
authenticated, the client will not be re-authenticated when received
from other VLANs. This option is useful for trunk ports to do per-VLAN
authentication control. When a port's authentication mode is changed
to multi-host, the previous authentication VLAN(s) on this port will be
cleared.
