ARP Attack Defense
If a switch continuously receives an enormous number of ARP messages on a specific port, it will not
function properly as CPU is overloaded and, worse still, may break up. ARP rate limit is just designed as a
solution to these problems. ARP rate limit enabled ports will enter a protection status and discard all ARP
messages received if they exceed the set threshold. When protection time ends, the ports will resume
forwarding ARP messages. Thus the switch is protected against such attack.
