4.9.9.1 Port Settings
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.
The IP Source Guard Port Setting and Information screens in Figure 4-9-60 & Figure 4-9-61 appear.
