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 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 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 re-authentication, which will fail. But if re-authentication 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.
