Enabling IPv4SG on an interface
When you enable IPSG on an interface, the static and dynamic IPSG are both enabled.
•
Static IPv4SG uses static bindings configured by using the
ip source binding
command.
•
Dynamic IPv4SG generates dynamic bindings from related source modules. IPv4SG uses the
bindings to filter incoming IPv4 packets based on the matching criteria specified in the
ip verify
source
command.
To implement dynamic IPv4SG, make sure the DHCP snooping or DHCP relay feature operates correctly
on the network.
To enable the IPv4SG feature on an interface:

If you configure this command on
an interface multiple times, the
most recent configuration takes
effect.
