The only IPv4 state that an L2 switch might contain for purpose of 
forwarding packets is if that switch implements SAVI like functionality.

The L2 switch doesn't need an ARP cache to perform its basic function. I 
have plenty of stupid L2 switches here in my household that doesn't have a 
management interface and doesn't understand IP at all. They only do 
ethernet header functions.
