Reset the MAC Address table.
Then read from a file line IP-MAC.
All unoccupied IP score MAC address 00:00:00:00:00:00
Well, on the switch is enabled, if there is, the option "Port security"


arp -d -a > /dev/null
arp -f /etc/ethers > /dev/null
echo 'Static ARP-table is loaded'

$cat /etc/ethers

10.0.0.64       D8:5D:4C:80:B1:4C       #Valya
...
