Description
Factory Default
device is plugged into a switch port or if a supplicant is no longer attached.
For MAC-based ports, reauthentication is only useful if the RADIUS
server configuration has changed. It does not involve communication
between the switch and the client, and therefore doesn't imply that a client
is still present on a port (see Aging Period below).
Reauthentication
Period
Determines the period, in seconds, after which a connected client must be
reauthenticated. This is only active if the Reauthentication Enabled
checkbox is checked. Valid values are in the range 1 to 3600 seconds.
3600
EAPOL Timeout
Determines the time for retransmission of Request Identity EAPOL
frames. Valid values are in the range 1 to 65535 seconds. This has no
effect for MAC-based ports.

Aging Period
This setting applies to the following modes, i.e. modes using the Port
Security functionality to secure MAC addresses:
• MAC-Based Auth.
When the NAS module uses the Port Security module to secure MAC
addresses, the Port Security module needs to check for activity on the
MAC address in question at regular intervals and free resources if no
activity is seen within a given period of time. This parameter controls
exactly this period and can be set to a number between 10 and 1000000
seconds.
If reauthentication is enabled and the port is in an 802.1X-based mode, this
is not so critical, since supplicants that are no longer attached to the port
will get removed upon the next reauthentication, which will fail. But if
reauthentication is not enabled, the only way to free resources is by aging
the entries.
For ports in MAC-based Auth. mode, reauthentication doesn't cause direct
communication between the switch and the client, so this will not detect
whether the client is still attached or not, and the only way to free any
resources is to age the entry.
300
Hold Time
This setting applies to the following modes, i.e. modes using the Port
Security functionality to secure MAC addresses:
• MAC-Based Auth.
If a client is denied access - either because the RADIUS server denies the
client access or because the RADIUS server request times out (according
to the timeout specified on the "Configuration→Security→AAA" page) -
the client is put on hold in the Unauthorized state. The hold timer does not
count during an on-going authentication.
In MAC-based Auth. mode, the switch will ignore new frames coming
from the client during the hold time.
The Hold Time can be set to a number between 10 and 1000000 seconds.

RADIUS-Assigned
QoS Enabled
RADIUS-assigned QoS provides a means to centrally control the traffic
class to which traffic coming from a successfully authenticated supplicant
is assigned on the switch. The RADIUS server must be configured to
transmit special RADIUS attributes to take advantage of this feature (see
RADIUS-Assigned QoS Enabled below for a detailed description).
The "RADIUS-Assigned QoS Enabled" checkbox provides a quick way to
globally enable/disable RADIUS-server assigned QoS Class functionality.
When checked, the individual ports' ditto setting determines whether
RADIUS-assigned QoS Class is enabled on that port. When unchecked,
RADIUS-server assigned QoS Class is disabled on all ports.

RADIUS-Assigned
VLAN Enabled
RADIUS-assigned VLAN provides a means to centrally control the VLAN
on which a successfully authenticated supplicant is placed on the switch.
Incoming traffic will be classified to and switched on the RADIUS-
assigned VLAN. The RADIUS server must be configured to transmit
special RADIUS attributes to take advantage of this feature (see RADIUS-
Assigned VLAN Enabled below for a detailed description).
