VLAN. The interval between transmissions of EAPOL Request Identity frames is configured with
‘EAPOL Timeout. If Allow Guest VLAN if EAPOL Seen’ enabled, the port will now be placed in the
Guest VLAN. If 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 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, and if one such 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:
Globally Disabled
:
NAS is globally disabled.
Link Down
:
NAS is globally enabled, but there is no link on the port.
Authorized
:
The port is in Force Authorized or a single-supplicant mode and the supplicant is
authorized.
Unauthorized
:
The port is in Force Unauthorized or a single-supplicant mode and the supplicant is
not successfully authorized by the RADIUS server.
X Auth/Y Unauth
:
The port is in a multi-supplicant mode. Currently,
X
clients are authorized and
Y
are unauthorized.
Restart
Two buttons in the ‘Restart’ column are available for each row. The buttons are only enabled when
authentication is globally enabled and the port's Admin State is in an EAPOL-based or MAC-based
mode.
Clicking these buttons will not cause settings changed on the page to take effect.
Reauthenticate
:
Schedules a reauthentication whenever the quiet-period of the port runs out
(EAPOL-based authentication). For MAC-based authentication, reauthentication will be attempted
immediately.
This button only has effect for successfully authenticated clients on the port and will not cause the
clients to get temporarily unauthorized.
Reinitialize
:
Forces a reinitialization of the clients on the port and thereby a reauthentication
immediately. The clients will transfer to the unauthorized state while the reauthentication is in
progress.
