HP 5500 HI Series Configuration Manual page 88

Users in the Auth-Fail VLAN can access a limited set of network resources, such as a software server, to
download anti-virus software and system patches.
The Auth-Fail VLAN does not accommodate 802.1X users that have failed authentication for
authentication timeouts or network connection problems. The way that the network access device
handles VLANs on the port differs by 802.1X access control mode.
For more information about VLAN configuration and MAC-based VLAN, see Layer 2
Configuration Guide.
1. On a port that performs port-based access control
Authentication status
A user fails 802.1X authentication
A user in the Auth-Fail VLAN fails 802.1X
re-authentication
A user passes 802.1X authentication
2. On a port that performs MAC-based access control
To perform the 802.1X Auth-Fail VLAN function on a port that performs MAC-based access control, you
must make sure that the port is a hybrid port, and enable MAC-based VLAN on the port.
Authentication status
A user fails 802.1X authentication
A user in the Auth-Fail VLAN fails 802.1X
re-authentication
A user in the Auth-Fail VLAN passes
802.1X authentication
NOTE:
The network device assigns a hybrid port to an 802.1X Auth-Fail VLAN as an untagged member.
VLAN manipulation
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.
•
Assigns the VLAN specified for the user to the port as the PVID,
and removes the port from the Auth-Fail VLAN. After the user
logs off, the user-configured PVID restores.
•
If the authentication server assigns no VLAN, the initial PVID
applies. The user and all subsequent 802.1X users are assigned
to the user-configured PVID. After the user logs off, the PVID
remains unchanged.
VLAN manipulation
Re-maps the MAC address of the user to the Auth-Fail VLAN. The
user can access only resources in the Auth-Fail VLAN.
The user is still in the Auth-Fail VLAN.
Re-maps the MAC address of the user to the server-assigned VLAN.
If the authentication server assigns no VLAN, re-maps the MAC
address of the user to the initial PVID on the port.
