802.1x protocol

Hello, ADD_Li.
The 802.1x protocol is a LAN access control protocol that complies with the IEEE 802 protocol set. It is also called the port-based network access control protocol. Port-based access control is a mechanism that allows an access device on a LAN to authenticate and control the identity of users or devices connected to the access device. Only authenticated users or devices can access the LAN through the access device. 802.1x authentication prevents unauthorized users or devices from accessing the network, ensuring the security of the transmission network.
Thanks!

Hi user! welcome to community

The 802.1X protocol is an interface-based network access control protocol. It controls users' access to network resources by authenticating the users on access interfaces.

- The client is the entity at an end of the LAN segment and is authenticated by a device at the other end of the link. The client is usually a user terminal. The user initiates 802.1X authentication using client software. The client must support Extensible Authentication Protocol over LAN (EAPoL).

- The device is the entity at an end of the LAN segment, which authenticates the connected client. The device is usually a network device that supports the 802.1X protocol. The device provides an interface, either physical or logical, for the client to access the LAN.

- The authentication server is the entity that provides authentication service for the device. The authentication server carries out authentication, authorization, and accounting on users, and is usually a RADIUS server.

802.1X is a port-based network access control protocol. "Port-based network access control" means authenticating and controlling the accessed user equipment at the level of the port of the LAN access device. If the user equipment connected to the port passes the authentication, the user equipment can access the resources in the LAN. If the authentication fails, resources on the LAN cannot be accessed.
