 RADIUS-Assigned
VLAN Enabled
When RADIUS-Assigned VLAN is both globally enabled and enabled (checked)
for a given port, the switch reacts to VLAN ID information carried in the RADIUS
Access-Accept packet transmitted by the RADIUS server when a supplicant is
successfully authenticated. If present and valid, the port's Port VLAN ID will be
changed to this VLAN ID, the port will be set to be a member of that VLAN ID,
and the port will be forced into VLAN unaware mode. Once assigned, all traffic
arriving 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 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 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
