ID must be a string of ASCII
chars in the range 0 to 9, which is interpreted as a decimal string
to represent the VLAN ID. Leading '0's are discarded. The final
value must be in the range of 1 to 4095.
Guest VLAN Enabled:
When Guest VLAN is both globally enabled and
enabled (checked) for a given port, the switch considers moving the port
into the Guest VLAN according to the rules outlined below.
This option is only available for EAPOL

Membership and VLAN Port" pages. These pages show which modules have
(temporarily) overridden the current Port VLAN configuration.
Guest VLAN Operation:
When a Guest VLAN enabled port's link comes up, the switch starts to
transmit EAPOL Request Identity frames. If the number of transmissions of
such frames exceeds Max. Reauth. Count and meanwhile no EAPOL frames
have been received, the switch considers entering the Guest VLAN. The
interval between the transmission of EAPOL request identity frames is
configured with EAPOL timeout. If “Allow Guest VLAN if EAPOL Seen” is
enabled, the port will now be placed in the Guest VLAN. If it’s disabled, the
switch will first check its history to see if an EAPOL frame has previously
been received on the port (this history is cleared if the port link goes down
or the port's Admin State is changed) and if not, the port will be placed in
the Guest VLAN. Otherwise, it will not move to the Guest VLAN but
continue transmitting EAPOL request identity frames at the rate given by
the EAPOL timeout.
Once in the Guest VLAN, the port is considered authenticated and all
attached clients on the port are allowed access on this VLAN. The switch
will not transmit an EAPOL success frame when entering the Guest VLAN.
While in the Guest VLAN, the switch monitors the link for EAPOL frames. If
such a frame is received, the switch immediately takes the port out of the
Guest VLAN and starts authenticating the supplicant according to the port
mode. If an EAPOL frame is received, the port will never be able to go back
into the Guest VLAN if the "Allow Guest VLAN if EAPOL Seen" is disabled.
Port State:
The current state of the port. It can undertake one of the
following values:
o
Globally Disabled:
NAS is globally disabled.
o
Link Down
: NAS is globally enabled, but there is no link on the port.
o
Authorized
: The port is in Force Authorized or a single
-
supplicant
mode and the supplicant is authorized.
o
Unauthorized
: The port is in Force Unauthorized or a single
-
supplicant
mode and the supplicant is not successfully authorized by the RADIUS
server.
o
X Auth/Y Unauth
: The port is in a multi
-
supplicant mode. Currently X
clients are authorized and Y are unauthorized.
