Hello,

 

Thanks for your suggestion.

I have found the root cause, it was due to one of the internal ips attacking 100+ plus of icmp packets to outside. 

Thanks.

I suspect you're seeing a cosmetic bug.
Otherwise, contact TAC to get this analyzed.

Hello,

 

Thanks for your suggestion.

I have found the root cause, it was due to one of the internal ips attacking 100+ plus of icmp packets to outside. 

Thanks.
