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 CONFIG level of the CLI.
device(config)# rate-limit-arp 100
This command 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.
The num variable specifies the number of ARP packets and can be from 0 through 100. If you specify 0, the device will not accept any ARP packets.
NOTE
If you want to change a previously configured the ARP rate limiting policy, you must remove the previously configured policy using the
no rate-limit-arp command before entering the new policy.
