802.1X User Settings

Users can set different local users on the Switch.
To view the following window, click Security > 802.1X > 802.1X User Settings:
Enter an 802.1X user name, password, and confirmation of that password. Properly configured local users will be displayed in the
802.1X User Table at the bottom of the window. Click Apply to implement configuration changes. Click Delete to remove the
specific entry.

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. Then the administrator must configure the
guest accounts accessing the Switch to be placed in a Guest
VLAN when trying to access the Switch. 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. If
authenticated and the authenticator possesses 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.
2. A port cannot be a member of a Guest VLAN and a static VLAN simultaneously.
3. Once a client has been accepted into the target VLAN, it can no longer access the Guest VLAN.
4. If a port is a member of multiple VLANs, it cannot become a member of the Guest VLAN.
