Supplicant wont send Authentication Failed log to ISE

Dear friends. i finally completed the configuration of switch for dot1x. then i tested by typing "test aaa group ise admin password new-code" and User rejected message appeared as expected because ISE authentication had not configured yet.And this log shown on ISE radius live logs. So, i created only Authentication Policy for testing purposes and configured windows 7 supplicant. So when i entered windows 7 domain user Authentication Fails as expected(Because Authorization Policy not configured yet). But this failure message didn't appear on Radius Live Logs. please see my switch configuration below and the result of "show authentication sessions"

Re: Supplicant wont send Authentication Failed log to ISE

The supplicant does not send logs to ISE.  When an authentication/authorization failure happens, ISE logs the message itself since it is the system failing the attempt.  By default, ISE is configured to suppress repeated failure and repeated successful attempts.  So when you are initially deploying ISE or just troubleshooting an issue, I recommend to turn off suppression.  Then once things are working as expected, turn suppression back on.  Go to Administration->System->Settings->Protocols->Radius.  That is where the suppression settings are.
