You can add permit clauses to forward ARP packets based on some matching criteria.

This example shows how to define an ARP access list and to permit both ARP requests and ARP 
responses from a host with an IP address of 1.1.1.1 and a MAC address of 0000.0000.abcd:

Switch(config)# arp access-list static-hosts

Switch(config-arp-nacl)# permit ip host 1.1.1.1 mac host 0000.0000.abcd

Switch(config-arp-nacl)# end

You can verify your settings by entering the show arp access-list privileged EXEC command.
