 Allow Guest VLAN if
EAPOL Seen
Port Configuration
The table has one row for each port on the selected switch in the stack and a number of columns, which are:
Object
 Port
 Admin State
enabled.
Valid values are in the range [1; 255].
The switch remembers if an EAPOL frame has been received on the port for the
life-time of the port. Once the switch considers whether to enter the Guest VLAN,
it will first check if this option is enabled or disabled. If disabled (unchecked;
default), the switch will only enter the Guest VLAN if an EAPOL frame has not
been received on the port for the life-time of the port. If enabled (checked), the
switch will consider entering the Guest VLAN even if an EAPOL frame has been
received on the port for the life-time of the port.
The value can only be changed if the Guest VLAN option is globally enabled.
Description
The port number for which the configuration below applies.
If NAS is globally enabled, this selection controls the port's authentication mode.
The following modes are available:
Force Authorized
In this mode, the switch will send one EAPOL Success frame when the port link
comes up, and any client on the port will be allowed network access without
authentication.
Force Unauthorized
In this mode, the switch will send one EAPOL Failure frame when the port link
comes up, and any client on the port will be disallowed network access.
Port-based 802.1X
In the 802.1X-world, the user is called the supplicant, the switch is the
authenticator, and the RADIUS server is the 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
