Hi everyone,
I was analyzing the securtiy logs of Aruba controller.
The controller's model is 650. And its version 6.1.3.5
I have recognized that some of the devices get Mic failed.
I try to understand why it happens.
Can it be a driver problem? Have you ever experienced these kind of problems?
Here is the some logs.
