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 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 "M

onitor→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.
