4.12.10 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. This page provides IP Source Guard
related configuration. The IP Source Guard Configuration screen in Figure 4-12-10 appears.
