Enable/Disable the DHCP Snooping function globally.
MAC Verify:
Enable or disable the MAC Verify feature. There are two fields
in the DHCP packet that contain the MAC address of the host.
The MAC Verify feature compares the two fields of a DHCP
packet and discards the packet if the two fields are different.
This prevents the IP address resource on the DHCP server
from being exhausted by forged MAC addresses.
