port’s configuration. But the prio
rity of Auto VLAN is higher than that of the user-set VLAN, that
is Auto VLAN is the one takes effect when the authentication is finished, while the user-set
VLAN do not work until the user become offline.
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.
