Hello Community,

 

i have a problem, one Notebook in our enviroment authenticates successfully with Host-Lookup (MAC-Adress) and get the right VLAN but then also sends permanantly  PEAP (EAP-MSCHAPv2)   requests with a diffrent Username ( Username is not an MAC-Adress) It is the Computername of Windows.

 

What is the Problem here ?

Hello Sebastian. A few questions:

- How is the supplicant configured on the Windows machines?

- Is 802.1x enabled on the supplicant?

- If possible please attach screenshots of the supplicant's configuration

- Is this for wireless, wired or both?

- Can you post screenshots of the ACS log page for those events along with a screenshot of the "detailed screen" for one of those events

 

Thank you for rating helpful posts!

What is the problem? Is the laptop supposed to send 802.1X frames or not? If not, you should instruct the desktop team to disable it or just choose to ignore the unsuccessful requests.
