Interface Filter-type Filter-mode IP-address Mac-address Vlan
--------- ----------- ----------- --------------- -------------- ---------
gi0/1 ip active 10.0.0.1 10
gi0/1 ip active deny-all 11-20
gi0/2 ip inactive-trust-port
gi0/3 ip inactive-no-snooping-vlan
gi0/4 ip-mac active 10.0.0.2 aaaa.bbbb.cccc 10
gi0/4 ip-mac active 11.0.0.1 aaaa.bbbb.cccd 11

In the previous example, this is the IP source guard configuration:
• On the Gigabit Ethernet 0/1 interface, DHCP snooping is enabled on VLANs 10 to 20. For
VLAN 10, IP source guard with IP address filtering is configured on the interface, and a binding
exists on the interface. For VLANs 11 to 20, the second entry shows that a default port is applied on
the interface for the VLANs on which IP source guard is not configured.
• The Gigabit Ethernet 0/2 interface is configured as trusted for DHCP snooping.
• On the Gigabit Ethernet 0/3 interface, DHCP snooping is not enabled on the VLANs to which the
interface belongs.
