IP Source Guard is a security feature that filters IPv4 traffic on network
interfaces based on manually configured entries in the IPv4 Source Guard
table, or dynamic entries in the DHCPv4 Snooping table when enabled (see
"DHCPv4 Snooping" on page 905
). IPv4 source guard can be used to
prevent traffic attacks caused when a host tries to use the IPv4 address of
a neighbor to access the network. This section describes commands used
to configure IPv4 Source Guard.
ip source-guard
binding
This command adds a static address to the source-guard ACL or MAC
address binding table. Use the
no
form to remove a static entry.
