NOOPING
The addresses assigned to DHCP clients on insecure ports can be carefully
controlled using the dynamic bindings registered with DHCP Snooping (or
using the static bindings configured with IP Source Guard). DHCP snooping
allows a switch to protect a network from rogue DHCP servers or other
devices which send port-related information to a DHCP server. This
information can be useful in tracking an IP address back to a physical port.

DHCP Snooping Process
•
Network traffic may be disrupted when malicious DHCP messages are
received from an outside source. DHCP snooping is used to filter DHCP
messages received on a non-secure interface from outside the network
