Guest VLAN ID:

Use this field to configure the guest VLAN ID.
Max. Reauth. Count:

Use this field to configure the number of times
moving the client to the guest VLAN.
Allow Guest VLAN if EAPOL Seen:

Use this check box to globally enable clients to be made members of the guest VLAN even if an EAPOL frame has been received on the
port to which the client is connected at any time during the lifetime of the port. If this check box is unchecked (default), the client only
becomes a member of the Guest VLAN if an EAPOL frame has not been received on the port to which the client is connected at any time
during the lifetime of the port.
Port Mode Configuration
Port:

This field shows the port number for this row.
Admin State:

If NAS is globally enabled, this selection controls the port's authentication mode. The following modes are available:
Force Authorized:

will be allowed network access without authentication.
Force Unauthorized:

port will be disallowed network access.
Port-based 802.1X:

authentication server. The authenticator acts as the man-in-the-middle, forwarding requests and responses between the supplicant and
the authentication server. Frames sent between the supplicant and the switch are special 802.1X frames, known as EAPOL (EAP Over
LANs) frames. EAPOL frames encapsulate EAP PDUs (RFC3748). Frames sent between the switch and the RADIUS server are
RADIUS packets. RADIUS packets also encapsulate EAP PDUs together with other attributes like the switch's IP address, name, and
the supplicant's port number on the switch. EAP is very flexible, in that it allows for different authentication methods, like MD5-Chal-
lenge, PEAP, and TLS. The important thing is that the authenticator (the switch) doesn't need to know which authentication method the
supplicant and the authentication server are using, or how many information exchange frames are needed for a particular method. The
switch simply encapsulates the EAP part of the frame into the relevant type (EAPOL or RADIUS) and forwards it. When authentication is
