What is agDosPortStatsTCPPortZero?
This Counter32 counts TCP packets where source or destination port is 0—a protocol violation. Network engineers watch this for suspicious traffic, as legitimate flows never use port 0. Example: sudden spikes indicate either misconfigured systems or scanning/attack activity.
