DESCRIPTION
"To detect unauthorized DHCP servers on a network, the DHCP snooping
device sends DHCP-DISCOVER messages through its downstream port
(which is connected to the DHCP clients).
If any response (DHCP-OFFER message) is received from the downstream port,
an unauthorized DHCP server is considered present, and then the device
sends a trap.
With unauthorized DHCP server detection enabled, the interface sends a
DHCP-DISCOVER message to detect unauthorized DHCP servers on the network.
If this interface receives a DHCP-OFFER message, the DHCP server which
sent it is considered unauthorized. "
