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' - '7', which translates into the desired QoS Class in the range [0; 7].

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 rules
