Description
Mode
Indicates if Network Access Server (NAS) is globally
enabled or disabled on the switch. If disabled, all
ports are allowed forwarding of frames.
Re-authentication Enabled
If checked, successfully authenticated supplicants/
clients are re-authenticated after the interval
specified by the Re-authentication Period.
For 802.1X-enabled ports, re-authentication can be
used to detect if a new device is plugged into a switch
port, or if a supplicant/client is no longer attached.
For MAC-based ports, re-authentication is only useful
if the RADIUS server configuration has changed. It
doesn’t involve communication between the switch
and the client, and therefore doesn’t imply that a
client is still present on a port.
Re-authentication Period
If Re-authentication is enabled, this value determines
the length of time after which a connected client
must be re-authenticated. Values are in the range of 1
to 3600 seconds.
EAPOL Timeout
Determines the time for re-transmission of Request
Identity EAPOL frames. Valid values are in the range
1 to 65535 seconds. This setting is not applicable for
MAC-based ports
