using the Port Security Limit Control functionality.
RADIUS-Assigned QoS Enabled
When RADIUS-Assigned QoS is both globally enabled and enabled
(checked) on 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].
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.
