ip arp-throttle threshold

Specifies the number of ARP packets per five-second period that the switch can receive from another device. (Default: 30.) Exceeding this rate places the source device on the blacklist. If the switch is configured to filter ARP packets as described for remediation mode (page yy), then the ARP packets received from blacklisted devices are dropped.


ip arp-throttle threshold <1 – 1024>


Configure the switch to blacklist a client from which it receives more than eight ARP packets in a five second period.

switch(config)#ip arp-throttle threshold 8
