You can create an ARP ACL to use with Dynamic ARP Inspection (DAI) and ARP Guard.
device# configure terminal
device(config)# arp access-list ARP_ACL_01
device(config-arp-acl)# permit ip host 1.1.1.1 mac host 0020.2222.2222 device(config-arp-acl)# permit ip host 1.1.1.2 mac host 0020.2222.2223
device# configure terminal device(config)# arp access-list ARP_ACL_01 device(config-arp-acl)# permit ip host 1.1.1.1 mac host 0020.2222.2222 device(config-arp-acl)# permit ip host 1.1.1.2 mac host 0020.2222.2223
