In the 802.1X authentication network, if a user uses a built-in 802.1X client of a PC operating system (such as Windows), the user cannot enter the user name and password proactively to trigger authentication.
For such users, the administrator configures 802.1X authentication triggered by a DHCP packet. After 802.1X authentication triggered by a DHCP packet is enabled, the device triggers 802.1X authentication for a user upon receiving a DHCP packet from the user. A built-in 802.1X authentication page of the operating system is automatically displayed on the user terminal. The user enters the user name and password for authentication.
Alternatively, 802.1X authentication triggered by a DHCP packet enables the user to implement authentication using the built-in 802.1X client of the operating system. After being authenticated, the user accesses an 802.1X client download web page to download and install the 802.1X client software, which facilitates fast network deployment.
