1.检查radius模板配置是否正确：
[NM-WH-WD-XXZX-H5700-L3-GigabitEthernet0/0/3]test-aaa test test radius-template 802.1x
Info: Account test succeed.
test-aaa测试时succeed，说明对接参数没有问题；
2.在认证的时候开启trace信息，trace终端的mac地址，关键信息如下：

Received a authentication reject packet from radius server(server ip = 192.168.253.100).//radius服务器回了一个reject报文；
在认证的时候在PC和radius服务器同时开启报文头分析，关键报文如下：
![]()
![]()
终端使用的是EAP-PEAP认证，服务器使用的EAP-MD5认证，二者不匹配
