MAC-Based Authentication
MAC-based authentication is an alternative to 802.1X authentication that allows
network access to devices (such as printers and IP phones) that do not have the
802.1X supplicant capability. MAC-based authentication uses the MAC address of
the connecting device to grant or deny network access.
In this case, the switch supports EAP MD5 functionality with the username and
password equal to the client MAC address, as shown below.
