IP Source Guard
– 250
IP Source Guard
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 “DHCP Snooping” on
page 242). 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.
