问题现象, 一台笔记本无线连接的是802.1x的网络,之前网络可以正常使用,之后微软系统发布漏洞更新,用户打上补丁,系统重启后,无线无法连接。在用户认证处一直验证不通过,ISE上报错如下:
Event 5411 Supplicant stopped responding to ISE
Failure Reason 12934 Supplicant stopped responding to ISE during PEAP tunnel establishment
Resolution Verify that supplicant is configured properly to conduct a full EAP conversation with ISE. Verify that NAS is configured properly to transfer EAP messages to/from supplicant. Verify that supplicant or NAS does not have a short timeout for EAP conversation. Check the network that connects the Network Access Server to ISE. Verify that ISE local server certificate is trusted on supplicant.
Root cause Supplicant stopped responding to ISE during PEAP tunnel establishment
