• 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 troubleshooting VLAN assignments, refer to 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].
