 RADIUS-Assigned
VLAN Enabled
Access-Accept packet.
Only the first occurrence of the attribute in the packet will be considered, and to
be valid, it must follow this rule:
All 8 octets in the attribute's value must be identical and consist of ASCII
characters in the range '0' - '3', which translates into the desired QoS Class in the
range [0; 3].
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
