Radius server unreachable events

[david_henderson]

vSZ version 5.2.0.0.699 with 411 R710s APs on campus. Every few days we are getting a bunch of radius server unreachable events. What is odd is the details of the event do not even point to our radius server. All events are reported like this

AP [Int301@F8:E7:1E:2A:A4:40] is unable to reach radius server [127.0.0.1].

Of course 127.0.0.1 is not our radius server. We are using Cloudpath as our radius server. Our wifi is rock solid so there are no other symptoms other than a rash of these events every few days.

Any ideas what causes this?

Is there a patch for 5.2.1 or just 5.2.0?

Hello Jeronimo and Raymond,

Can you please open up a TAC case so that we can verify if you are facing same issue on your setup and all details would be shared by the case. This issue has been seen on 5.2.0 (with few customer's only) and reload of controller or restart of radiusproxy service resolve's it, hence it is necessary to validate the logs before applying the patch. @EightOhTwoEleven On 5.2.1 we do not have this issue validated as of now.

Best Regards
Vineet
