supplicant software to authenticate. The advantage of MAC-based authentication
over 802.1X-based authentication is that the clients don't need special supplicant
software to authenticate. The disadvantage is that MAC addresses can be spoofed by
malicious users - equipment whose MAC address is a valid RADIUS user can be
used by anyone. Also, only the MD5-Challenge method is supported. The maximum
number of clients that can be attached to a port can be limited using the Port Security
Limit Control functionality.
When RADIUS-Assigned QoS is both globally enabled and enabled (checked) for a
given port, the switch reacts to QoS Class information carried in the RADIUS
Access-Accept packet transmitted by the RADIUS server when a supplicant is
successfully authenticated. If present and valid, traffic received on the supplicant's
port will be classified to the given QoS Class. If (re-)authentication fails or the
RADIUS Access-Accept packet no longer carries a QoS Class or it's invalid, or the
supplicant is otherwise no longer present on the port, the port's QoS Class is
immediately reverted to the original QoS Class (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
RADIUS attributes used in identifying a QoS Class:
Refer to the written documentation for a description of the RADIUS attributes needed
in order to successfully identify a QoS Class. The User-Priority-Table attribute
defined in RFC4675 forms the basis for identifying the QoS Class in an
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
