If the probe exceeds the maximum number defined at [2.2.4. Maximum ARP Packet per sec],
you can suspend and control the ARP packet generation for a brief period to prevent traffic
overflow. The probe will not generate more than 100 ARP packets within the period.
Below default setting will suspend ARP generation for one second if the probe exceeds 5,000
packets per second limit.

assign a short period.
