The 802.1X guest VLAN on a port accommodates users who have not performed 802.1X authentication.
Users in the guest VLAN can access a limited set of network resources, such as a software server, to
download antivirus software and system patches. Once a user in the guest VLAN passes 802.1X
authentication, it is removed from the guest VLAN and can access authorized network resources.
The following table describes how the access device handles VLANs on an 802.1X-enabled port:
Authentication status VLAN mani
p
ulation
A user has not passed 802.1X
authentication and is in the
authentication process.
The device assigns the 802.1X guest VLAN to the port as the PVID. All
802.1X users on this port can access only resources in the guest VLAN.
If no 802.1X guest VLAN is configured, the access device does not perform
any VLAN operation.
A user in the 802.1X guest
VLAN fails 802.1X
authentication.
If an 802.1X Auth-Fail VLAN (see "Auth-Fail VLAN") i
s available, the device
assigns the Auth-Fail VLAN to the port as the PVID. All users on this port can
access only resources in the Auth-Fail VLAN.
If no Auth-Fail VLAN is configured, the PVID on the port is still the 802.1X
guest VLAN. All users on the port are in the guest VLAN.
A user in the 802.1X guest
VLAN passes 802.1X
authentication.
• The device assigns the authorization VLAN of the user to the port as the
PVID, and it removes the port from the 802.1X guest VLAN. After the user
logs off, the port is assigned back to the guest VLAN.
• If the authentication server does not authorize a VLAN, the initial PVID
applies. The user and all subsequent 802.1X users are assigned to the
initial port VLAN. After the user logs off, the port is assigned back to the
guest VLAN.
NOTE:
The initial PVID of an 802.1X-enabled port refers to the PVID used by the port
before the port is assigned to any 802.1X VLANs.
Auth-Fail VLAN
Only ports that perform port-based access control support the Auth-Fail VLAN.
The 802.1X Auth-Fail VLAN on a port accommodates users who have failed 802.1X authentication
because of the failure to comply with the organization security strategy, such as using a wrong password.
Users in the Auth-Fail VLAN can access a limited set of network resources, such as a software server, to
download antivirus software and system patches.
The Auth-Fail VLAN does not accommodate 802.1X users who have failed authentication for
authentication timeouts or network connection problems.
The following table describes how the access device handles VLANs on an 802.1X-enabled port:
Authentication status VLAN mani
p
ulation
A user fails 802.1X
authentication.
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.
A user in the 802.1X Auth-Fail
VLAN fails 802.1X
reauthentication
The Auth-Fail VLAN is still the PVID on the port, and all 802.1X users on this
port are in this VLAN.
