Re: Deauthenticate request from client. Reason code: (value='Sending station is leaving IBSS or ESS
Is this just specific to one or some client?
OR
All of the client having problem associating to the SSID?
Looks like the authenticaiton failures causing the issue, AP is sending the EAP-Identity request to the client according to the logs.. .but there is no response coming back:

there should Identity Response... but i dont see one
Either the client received the Identity Request but didnt response to it?
OR
The client did not receive the Identity Request from the AP.. might be lost in the air due to noise/interference?
Did you disable any lower data rates on the VSC profile? If so, you may want to enable the lower data rates and try if that helps..
Alternatively, it could be the certificate on the client/server side is not matching each other.. and subsequently its failing?

Hello RamKrish,
thank you very much for yoour response.
Is this just specific to one or some client?
To some clients.
All of the client having problem associating to the SSID?
No all the clients.
Looks like the authenticaiton failures causing the issue, AP is sending the EAP-Identity request to the client according to the logs.. .but there is no response coming back:
Oct 21 12:47:08 PACCPOL11I eapolserver: Sending EAPOL (frame-length='30') EAP Identity Request (length='12',id='91') to station (mac-address='00:07:88:C8:B7:9B').

There should be an "Accepted Identity Response"... I don't know why the client doen't send the identity...
Either the client received the Identity Request but didnt response to it?
OR
The client did not receive the Identity Request from the AP.. might be lost in the air due to noise/interference?
I don't know, I don't have a sniffer in the client side.
Did you disable any lower data rates on the VSC profile? If so, you may want to enable the lower data rates and try if that helps..
No, I don't disable any lower data rates.
Alternatively, it could be the certificate on the client/server side is not matching each other.. and subsequently its failing?
I think the certificates are not the problem because this client (00:07:88:C8:B7:9B) was authenticated earlier.
Thank you very much

Re: Deauthenticate request from client. Reason code: (value='Sending station is leaving IBSS or ESS
Unless we know why the client is not responding, there is no way to isoalte this issue.
Better to do a wireless sniffing (you can use Apple Macbook - sniffer tool to capture wireless packet capture), to see if the client has received the EAP packet from AP or not. Then subsequently if the client has responded to those EAP or not.
If you still face issues, suggest to raise a support case to take more closer look at other data that might possibly explain the authenticaiton failures.
