arpwatch

Description

Arpwatch maintains a database of Ethernet MAC addresses seen on the network, with their associated IP pairs. Alerts the system administrator via e-mail if any change happens, such as new station/activity, flip-flops, changed and re-used old addresses.

If you want to maintain a list authorized MAC addresses manually, take a look at the arpalert package which may fit your needs better.
