ARP Storm Control

ARP Storm Control is used to protect the CPU filtering mechanism from ARP broadcast storms. ARP
packets being sent to the CPU filtering mechanism can be limited by setting the ARP Storm Control
Threshold. The threshold determines the allowable number of ARP packets (measured in Kbytes per
second) that the CPU filtering mechanism can process. If an ARP broadcast storm occurs, and the
ARP Storm Control Threshold is exceeded, the Switch will drop the packet. The threshold must be a
multiple of 8 between 8 and 1024. To view the ARP Storm Control Settings window, click Security >
ARP Storm Control.
