Usage Guidelines

To prevent the CPU from becoming flooded by ARP packets in a busy network, you can restrict the number of ARP packets the device will accept each second. When you configure an ARP rate limit, the device accepts up to the maximum number of packets you specify, but drops additional ARP packets received during the one-second interval. When a new one-second interval starts, the counter restarts at zero, so the device again accepts up to the maximum number of ARP packets you specified, but drops additional packets received within the interval.

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.

The no form of the command disables ARP rate limiting.

Examples

The following example configures the device to accept up to 100 ARP packets each second. 

device(config)# rate-limit-arp 100
