On most Etherent interfaces the MAC address can be assigned using ifconfig or "ip link". If you want multiple MAC addresses on the same interface then there is MAC vlans available from the vlan home page. > The topology of LAN we are using is star.

This sounds very much like what is already provided by several of the the vrrp daemons for Linux. The daemon makes sure only one of the servers have the MAC and IP active at a time.
