Overview of IP Source Guard

Similar to DHCP snooping, this feature is enabled on a DHCP snooping untrusted 
Layer 2 port. Initially, all IP traffic on the port is blocked except for DHCP 
packets that are captured by the DHCP snooping process. When a client receives 
a valid IP address from the DHCP server, or when a static IP source binding is 
configured by the user, a per-port and VLAN Access Control List (PVACL) is 
installed on the port. This process restricts the client IP traffic to those 
source IP addresses configured in the binding; any IP traffic with a source IP 
address other than that in the IP source binding will be filtered out. This 
filtering limits a host's ability to attack the network by claiming a neighbor 
host's IP address.
