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) 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].
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.
