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 between retransmission of Request Identity EAPOL frames.
Valid values are in the range 1 to 255 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
the entry.
 Hold Time  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
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.
