On a network where 802.1X authentication is used, if a user uses a built-in 802.1X client of a PC operating system (such as Windows XP), the user cannot enter the user name and password to trigger authentication.
To solve the problem, enable 802.1X authentication triggered by unicast packets. This function enables the device to send a unicast packet to respond to the received ARP or DHCP Request packet. After the user PC receives the unicast packet from the device, the built-in 802.1X authentication page is displayed. The user then can enter the user name and password for authentication.
After 802.1X authentication triggered by unicast packets is enabled, users can use built-in 802.1X clients for authentication. After being authenticated, users can access 802.1X clients to download and install 802.1X client software, which facilitates fast network deployment.
