IP Source Guard Commands

IP Source Guard is a security feature that filters IP traffic on network interfaces based on manually configured entries in the IP Source Guard table, or static and dynamic entries in the DHCP Snooping table when enabled (see “DHCP Snooping Commands” on page 4-317). IP source guard can be used to prevent traffic attacks caused when a host tries to use the IP address of a neighbor to access the network. This section describes commands used to configure IP Source Guard.
