18.2.2 Guest VLAN

When 802.1x port authentication is enabled on the Switch and its ports, clients that do not have the
correct credentials are blocked from using the port(s). You can configure your Switch to have one
VLAN that acts as a guest VLAN. If you enable the guest VLAN (102 in the example) on a port (2 in
the example), the user (A in the example) that is not IEEE 802.1x capable or fails to enter the
correct username and password can still access the port, but traffic from the user is forwarded to
the guest VLAN. That is, unauthenticated users can have access to limited network resources in the
same guest VLAN, such as the Internet. The rights granted to the Guest VLAN depends on how the
network administrator configures switches or routers with the guest network feature.

Specify the length of time required to pass before a client has to re-enter his or her
username and password to stay connected to the port.
Specify the number of seconds the port remains in the HELD state and rejects further
authentication requests from the connected client after a failed authentication exchange.
Specify the number of seconds the Switch waits for client's response before re-sending an
identity request to the client.
Specify the number of seconds the Switch waits for client's response to a challenge request
