configured on the "Configuration→Security→AAA" page. The IEEE802.1X
standard defines port-based operation, but non-standard variants overcome security
limitations as shall be explored below.
MAC-based authentication allows for authentication of more than one user on the
same port, and doesn't require the user to have special 802.1X supplicant software
installed on his system. The switch uses the user's MAC address to authenticate
against the backend server. Intruders can create counterfeit MAC addresses, which
makes MAC-based authentication less secure than 802.1X authentication.
The NAS configuration consists of two sections, a system- and a port-wide.
System Configuration
Mode
Indicates if NAS is globally enabled or disabled on the switch. If globally disabled, all
ports are allowed forwarding of frames.
Reauthentication Enabled
If checked, successfully authenticated supplicants/clients are reauthenticated after the
interval specified by the Reauthentication Period. Reauthentication for 802.1X-enabled
