Guest VLAN Enabled
on the port will be classified and switched on the RADIUS-assigned VLAN ID.
If (re-)authentication fails or the RADIUS Access-Accept packet no longer carries a
VLAN ID or it's invalid, or the supplicant is otherwise no longer present on the port,
the port's VLAN ID is immediately reverted to the original VLAN ID (which may be
changed by the administrator in the meanwhile without affecting the
RADIUS-assigned).
This option is only available for single-client modes, i.e.
• Port-based 802.1X
• Single 802.1X
For trouble-shooting VLAN assignments, use the "Monitor→VLANs→VLAN
Membership and VLAN Port" pages. These pages show that which modules have
(temporarily) overridden the current Port VLAN configuration.
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].
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 that 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
