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 4-269). 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.
