Configuring Option 82

DHCP with Option 82 attaches authentication messages to the packets sent from
the host. DHCP passes the configuration information to hosts on a TCP/IP network.
This permits network administrators to limit address allocation to authorized hosts.
DHCP with Option 82 can be enabled only if DHCP snooping is enabled.
