5.13.5 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 ”). 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.
