HP FlexFabric 5700 Series Security Configuration Manual page 87

The Auth-Fail VLAN does not accommodate 802.1X users who have failed authentication for
authentication timeouts or network connection problems.
The access device handles VLANs on an 802.1X-enabled port based on its 802.1X access control
method.
On a port that performs port-based access control:
•
Authentication status
A user fails 802.1X
authentication.
A user in the 802.1X
Auth-Fail VLAN fails 802.1X
authentication because of
any other reason except for
unreachable servers.
A user passes 802.1X
authentication.
On a port that performs MAC-based access control:
•
Authentication status
A user fails 802.1X
authentication.
A user in the 802.1X
Auth-Fail VLAN fails 802.1X
authentication because of
any other reason except for
unreachable servers.
A user in the 802.1X
Auth-Fail VLAN passes
802.1X authentication.
For the 802.1X Auth-Fail VLAN feature to take effect on a port that performs MAC-based access
control, make sure the following requirements are met:
The port is a hybrid port.
MAC-based VLAN is enabled on the port.
The access device assigns a hybrid port to an 802.1X Auth-Fail VLAN as an untagged member.
For more information about VLAN configuration and MAC-based VLANs, see Layer 2—LAN
Switching Configuration Guide.
VLAN manipulation
The device assigns the Auth-Fail VLAN to the port as the PVID. All 802.1X
users on this port can access only resources in the Auth-Fail VLAN.
The Auth-Fail VLAN is still the PVID on the port, and all 802.1X users on
this port are in this VLAN.
•
The device assigns the authorization VLAN of the user to the port as
the PVID, and it removes the port from the Auth-Fail VLAN. After the
user logs off, the guest VLAN is assigned to the port as the PVID. If no
guest VLAN is configured, the initial PVID of the port is restored.
•
If the authentication server does not authorize a VLAN, the initial PVID
of the port applies. The user and all subsequent 802.1X users are
assigned to the initial PVID. After the user logs off, the PVID remains
unchanged.
VLAN manipulation
The device maps the MAC address of the user to the 802.1X Auth-Fail
VLAN. The user can access only resources in the Auth-Fail VLAN.
The user is still in the Auth-Fail VLAN.
The device remaps the MAC address of the user to the authorization
VLAN.
If the authentication server does not authorize a VLAN, the device remaps
the MAC address of the user to the initial PVID on the port.
