In my previous post I have said VSX bypass debug commands do not work. I was wrong.
The trick works perfectly on R75.40VS Management, both SmartCenter and MDM.
Nevertheless, the weird part is that it only works if one types the commands manually and not by copy / paste. I guess it was only about some weird corruption when pasted from the buffer.
I am sorry for being wrong before and for all time spent on this topic by David Bar, Shahar Solomon, Eran Ashkenazi and other Check Point engineers. I appreciate the assistance.
