Parameter Description
Mode Indicates if NAS is globally enabled or disabled on the switch. If globally
disabled, all ports can forward 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 does not 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.
EAPOL Timeout Determine 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 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 does not 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
