Mode
Indicates if NAS is globally enabled or disabled on the switch. If globally disabled,
all ports are allowed forwarding of frames.
Reauthentication
Enabled
If checked, successfully authenticated supplicants/clients are reauthenticated
after the interval specified by the Reauthentication Period. Reauthentication for
802.1X-enabled ports can be used to detect if a new 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.
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.
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:
■
Single 802.1X
■
Multi 802.1X
■
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 a 802.1X-based mode, this is not
so criticial, 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
