Supplicant’s NIC Setting
STEP 1: Configure a static IP address 20.20.20.10 and net mask 255.255.255.0 for supplicant. (If there is a DHCP server to assign IP
address for supplicant, this step can be ignored.)
STEP 2: Select the IEEE802.1x Authentication Enable check box, then configure the EAP type to MD5-Challenge.
After setting this function in the NIC, the supplicant should enter a correct pair of account and password to use this Ethernet port
service from the switch.
