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) 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:
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' - '7', which translates into the
desired QoS Class in the range [0; 7].
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 troubleshooting VLAN assignments, use the " VLANs→VLAN
Membership Status and VLAN Port Status pages. These pages show
which modules have (temporarily) overridden the current Port VLAN
configuration.
