Description (partial)


Shut, no shut and Line rate traffic simultaneously happening from more than atleast 3 hosts on a multi-auth port. 


The issue happens when the traffic is sent at exactly the same instant there is a no shut. Even with a 1second delay, issue is not seen.
In real networks, the probability of sending traffic immediately at no shut  without a 1 millisecond gap is very low.
