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.

given port. All means all ports will have one specific setting.

ports. This value can be 0, 1, 2 and unlimited. If the port mode is enabled
and the value of max dynamic client is equal 0, it means only allow the IP
