Hello Developers,

 

I am working on Cisco ISE and I find the Wireshark tool very beneficial to analyze different packets. So Cheers to all your hard work!!!

I am using Windows 10 (Insider Preview Build with TEAP support) endpoint  with the latest version of Wireshark running (Version 3.2.1 (v3.2.1-0-gbf38a67724d0)).

Currently there is a new TEAP protocol (Tunneled EAP protocol - RFC 7170) , and we tried to analyze the TEAP traffic on Wireshark but Wireshark shows the Code-Type in EAP as ‘Unknown’ instead of ‘TEAP’ even though it identifies the code as 55. Also, could you please let me know if there be way to analyze the TEAP traffic by adding certificate to Wireshark.

 

Kindly please have a look at the attached Wireshark screenshots of TEAP Traffic and PEAP traffic so as to have a better comparison and understanding of the issue.

Hope to see this issue resolved soon!

 

Regards,

Nikhil Jadhav
