 The switch looks for the first set of these attributes that have the same Tag value and fulfil the
following requirements (if Tag == 0 is used, the Tunnel-Private-Group-ID does not need to include a
Tag):
 Value of Tunnel-Medium-Type must be set to "IEEE-802" (ordinal 6).
 Value of Tunnel-Type must be set to "VLAN" (ordinal 13).
 Value of Tunnel-Private-Group-ID must be a string of ASCII chars in the range '0' - '9',
which is interpreted as a decimal string representing the VLAN ID. Leading '0's are
discarded. The final value must be in the range [1; 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-based modes, i.e.:
 Port-based 802.1X
 Single 802.1X
 Multi 802.1X
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
