Rate limiting ARP Packets

To limit the number of ARP packets the device will accept each second, enter the rate-limit-arp command at the global configuration level of the CLI. 

device(config)# rate-limit-arp 100

This example configures the device to accept up to 100 ARP packets each second. If the device receives more than 100 ARP packets during a one-second interval, the device drops the additional ARP packets during the remainder of that one-second interval.

Note: If you want to change a previously configured ARP rate limiting policy, you must remove the previously configured policy using the no rate-limit-arp command before entering the new policy.
