FreeRadius Re-Authentication Latency

[Smith, James]

Submitted as a larger email last time. The attached file is now compressed and email should be a smaller size. 

Hello, 
I'm currently experiencing a latency issue with Siemens base stations and CPEs re-authenticating to our FreeRadius server running version 3.0.4. (I understand this version is a little old and should be updated. We will look into this in the new future) 

Attached is my log file after running FreeRadius in debug mode. CPE9 at siemens.com is the specific host I'd like to look at but all of our CPEs are experiencing the same issue. We use EAP-TTLS for authentication and it looks like it takes many sessions (167 from what I can tell by looking at the Access-Request ID) to actually complete the re-authentication process. The amount of sessions may vary for each CPE as they can take 2-10 minutes to actually authenticate. 

It starts on line 3546 and finally authenticates on line 18927. 

CPE (Suplicant) ----> NAS-Identifier = "BS" (Authenticator) ------> Radius Server 

Please let me know if you have any questions and/or if you think I have to tweak my configuration somewhere to speed this up. 


Thanks for the help,
James Smith
