IP Source Guard is a secure feature used to restrict IP traffic on
DHCP snooping untrusted ports
by filtering traffic based on
the DHCP Snooping Table or manually configured IP Source Bindings. It helps prevent IP spoofing attacks when a host tries to
spoof and use the IP address of another host.

Figure 4-9-38
