Guest VLAN Settings
On 802.1X security-enabled networks, there is a need
for non- 802.1X supported devices to gain limited
access to the network, due to lack of the proper 802.1X
software or incompatible devices, such as computers
running Windows 98 or older operating systems, or the
need for guests to gain access to the network without
full authorization or local authentication on the Switch.
To supplement these circumstances, this switch now
implements 802.1X Guest VLANs. These VLANs
should have limited access rights and features separate
from other VLANs on the network.
To implement 802.1X Guest VLANs, the user must first
create a VLAN on the network with limited rights and
then enable it as an 802.1X guest VLAN. Upon initial
entry to the Switch, the client wishing services on the
Switch will need to be authenticated by a remote
RADIUS Server or local authentication on the Switch to
be placed in a fully operational VLAN.
Figure 8-12 Guest VLAN Authentication Process
If authenticated and the authenticator possess the VLAN placement information, that client will be accepted into the
fully operational target VLAN and normal switch functions will be open to the client. If the authenticator does not
have target VLAN placement information, the client will be returned to its originating VLAN. Yet, if the client is
denied authentication by the authenticator, it will be placed in the Guest VLAN where it has limited rights and
access. The adjacent figure should give the user a better understanding of the Guest VLAN process.
Limitations Using the Guest VLAN
1. Ports supporting Guest VLANs cannot be GVRP enabled and vice versa.
