The EAP protocol message in the 802.1X authentication process is a BPDU message. For BPDU packets, Huawei's switch equipment currently does not perform Layer 2 forwarding by default. Therefore, if there is a Layer 2 switch between the 802.1X-enabled device and the user, Layer 2 transparent transmission must be configured on it. Otherwise, the EAP packets sent by the user will not reach the authentication device, and the authentication will fail.
