End goal: Make a script that will limit the number of outgoing ARP requests in a second using arptables.

This is to have the ability to not trip the ARP-limiting feature on Cisco devices.

I want to make it in a shell-script, but if anyone has any thoughts or ideas, I am more than happy to listen.


Have you tried ebt_limit?

ebtables -A OUTPUT -o eth0 -p ARP --limit 100/second -j ACCEPT
ebtables -A OUTPUT -o eth0 -p ARP -j DROP
