4.9.1.4 Guest VLAN Setting
Overview
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 meantime, the
sw
itch 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.
The 802.1X Guest VLAN setting screens in Figure 4-9-7 & Figure 4-9-8 appear.
