RADIUS attributes used in identifying a VLAN ID:
RFC2868 and RFC3580 form the basis for the attributes
used in identifying a VLAN ID in an Access-Accept packet.
The following criteria are used:
• The Tunnel-Medium-Type, Tunnel-Type, and
Tunnel-Private-Group-ID attributes must all be present at
least once in the Access-Accept packet.
• The switch looks for the first set of these attributes that
have the same Tag value and fulfill 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.

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 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 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
