auth auth-fail vlan
Overview
Use this command to enable the
auth-fail vlan
feature on the specified vlan
interface. This feature assigns supplicants (client devices) to the specified VLAN if
they fail port authentication.
Use the
no
variant of this command to disable the
auth-fail vlan
feature for a
specified VLAN interface.
Syntax
auth auth-fail vlan <
1-4094
>
no auth auth-fail vlan
Default
The
auth-fail vlan
feature is disabled by default.
Mode
Interface Configuration for a static channel, a dynamic (LACP) channel group, or a
switch port.
Usage
Use the
auth-fail vlan
feature when using Web-Authentication instead of the
Guest VLAN feature, when you need to separate networks where one supplicant
(client device) requires authentication and another supplicant does not require
authentication from the same interface.
This is because the DHCP lease time using the Web-Authentication feature is
shorter, and the
auth fail vlan
feature enables assignment to a different VLAN if a
supplicant fails authentication.
To enable the
auth-fail vlan
feature with Web Authentication, you need to set
Web Authentication Server virtual IP address by using the
auth-web-server
ipaddress
command or the
auth-web-server dhcp ipaddress
command.
When using 802.1X port authentication, use a
dot1x max-auth-fail
command to set
the maximum number of login attempts. Three login attempts are allowed by
default for 802.1X port authentication before supplicants trying to authenticate
are moved from the Guest VLAN to the auth-fail VLAN. See the
dot1x max-auth-fail
on page 1011 for command information.
See the
Authentication Feature Overview and Configuration Guide
for information
about:
•
the auth-fail VLAN feature, which allows the Network Administrator to
separate the supplicants who attempted authentication, but failed, from the
supplicants who did not attempt authentication, and
•
restrictions regarding combinations of authentication enhancements
working together
Use appropriate ACLs (Access Control Lists) on interfaces for extra security if a
supplicant allocated to the designated auth-fail vlan can access the same network
Parameter
Description
<
1-4094
>
Assigns the VLAN ID to any supplicants that have failed port
authentication.
