Ip Source Guard. 19 Configuring DHCP Snooping and IP Source Guard IP Source Guard (IPSG) is a network security feature implemented primarily on Layer 2 network switches to mitigate IP address spoofing attacks In higher-end Catalyst switch models, such as the Catalyst 4500 and Catalyst 6500 series switches, IP Source Guard is enabled using the ip verify source vlan dhcp-snooping [port-security] interface configuration command

The feature uses dynamic DHCP snooping and static IP source binding to matc h IP addresses to hosts on untrusted Layer 2 access The following output illustrates how to enable IP Source Guard on a Catalyst 4500 or Catalyst 6500. When IP Source Guard is enabled, the switch drops incoming packets that do not match a binding in the bindings database
