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 22-7). 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.
