This invention proposes an access authentication method that binds switch ports to hosts, addressing the challenges of server-side port verification and high management complexity when multiple clients access the network. This method aggregates switch port information (switch identifier + port number) into logical users and binds them to client certificates for unified authentication. Clients can obtain current port information via a link-layer discovery protocol and submit authentication requests in the form of "switch identifier - port number." The authentication server verifies the connection based on stored port information, logical users, and certificate public keys. If the connection port does not match the binding relationship, access is rejected. The authentication request includes the MAC address of the first connected switch to prevent switch spoofing. This technology effectively improves authentication security and flexibility. When network configuration changes, only the binding relationship needs to be updated on the server side, without modifying client configurations, thus significantly reducing the management burden.
