Notes: At present, Auto VLAN can only be used in the port-based access control mode, and on
the ports whose link type is Access.
2. Guest VLAN
Guest VLAN feature is used to allow the unauthenticated user to access some specified
resources.
The user authentication port belongs to a default VLAN (Guest VLAN) before passing the
802.1x authentication, with the right to access the resources within this VLAN without
authentication. But the resources in other networks are beyond reach. Once authenticated, the
port will leave Guest VLAN, and the user can access the resources of other networks.
In Guest VLAN, users can get 802.1x supplicant system software, update supplicant system or
update some other applications (such as anti-virus software, the patches of operating system).
The access device will add the port into Guest VLAN if there is no supplicant getting
authenticated successfully in a certain stretch of time because of lacking exclusive
authentication supplicant system or the version of the supplicant system being too low.
Once the 802.1x feature is enabled and the Guest VLAN is configured properly, a port will be
added into Guest VLAN, just like Auto VLAN, if there is no response message from the
supplicant system after the device sends more authentication-triggering messages than the
upper limit (EAP-Request/Identity) from the port.

The authentication server assigns an Auto VLAN, and then the port leaves Guest
VLAN and joins the assigned Auto VLAN. When the user becomes offline, the port will
be allocated to the specified Guest VLAN again.
