For trouble-
shooting VLAN assignments, use the "Monitor→VLANs→VLAN
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 transmitting
EAPOL Request Identity frames. If the number of transmissions of such frames
exceeds
Max. Reauth. Count and no EAPOL frames have been received in the
meanwhile, the switch considers entering the Guest VLAN. The interval between
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 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.
6. 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.
7. Restart :
Two buttons 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.
