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 dynamic entries in the DHCP Snooping table when enabled (see
). 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.
