Resolution

The firmware in the AS will temporarily shut down its Ethernet connection when exposed to a broadcast storm or DoS attack in order to protect the application in terms of control programs and IO.

A side effect of this is that the communication to external IP devices is temporarily unavailable during the the storm/attack.
