I would like to apply an ARP rate limiter on my C6500.
The average ARP traffic is low, however, every 60 seconds, there is a peak, some times close from 1Mbps.
This peak is due to unicast ARP request; I have readen in other discussions that these ARP unicast request are generated by Cisco to refresh the ARP table.
So I could police ARP traffic to 1Mbps to avoid drops during these peaks, but this limit seems really high, and I ask myself if it is finally really necessary.
What's your experience about that?
Use ARP policing,
Allowing 1Mbps is not advisable. however you can tweak the values according to your environment.
