IP Source Guard
IP Source Guard uses the DHCP snooping bindings database. When IP Source Guard is
enabled, the switch drops incoming packets that do not match a binding in the bindings
database. IP Source Guard can be configured to enforce just the source IP address or both
the source IP address and source MAC address.
