How to validate failed MAC in Import Endpoint Identity Group

[Eranna]

Hi all,

I have more than 800 endpoint needs to be added in different assignment group. When I am importing I am getting around 150+ endpoints as a failed. How to validate particularly which endpoint is failed. 

Thank you.

context visibility > endpoints 

check status 
it must show you imported 
if not then this endpoints have issue

Verifying one by one will consume more time.

In my case out of 800 endpoint only 150 are failed. I need to get failed endpoint details only to check further.

I hope my query is conveyed well. Attached sample screenshot. Here it is saying that click cancel to see list of endpoint imported. I am not able to see anything. Any other way can I validate. 

Please let me know where can I see those results.
