IP source guard configuration
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 Configuration page
provides IP Source Guard-related configuration data.
