Mode
Re Authentication
Enabled
Re Authenication Period
EAPOL Timeout
Description
Indicates if NAS is globally enabled or disabled on the switch. If globally disabled, all ports are
allowed forwarding of frames.
If checked, successfully authenticated supplicants/clients are Re Authenticated after the
interval specified by the Re Authentication Period. Re Authentication 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, re authentication 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).
Determines the period, in seconds, after which a connected client must be Re Authenticated.
This is only active if the Re Authentication Enabled checkbox is checked. Valid values are in
the range 1 to 3600 seconds.
Determines the time for retransmission of Request Identity EAPOL frames. Valid values are in
the range of 1 to 255 seconds. This has no effect for MAC-based ports.
