This is an example of output from the
show ip verify source
command:
Switch>
show ip verify source
Interface Filter-type Filter-mode IP-address Mac-address Vlan
--------- ----------- ----------- --------------- -------------- ---------
gi1/1 ip active 10.0.0.1 10
gi1/1 ip active deny-all 11-20
gi1/2 ip inactive-trust-port
gi1/3 ip inactive-no-snooping-vlan
gi1/4 ip-mac active 10.0.0.2 aaaa.bbbb.cccc 10
gi1/4 ip-mac active 11.0.0.1 aaaa.bbbb.cccd 11
gi1/4 ip-mac active deny-all deny-all 12-20
gi1/5 ip-mac active 10.0.0.3 permit-all 10
gi1/5 ip-mac active deny-all permit-all 11-20
In the previous example, this is the IP source guard configuration:
•
On the Gigabit Ethernet 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 access control lists (ACLs)
is applied on the interface for the VLANs on which IP source guard is not configured.
•
The Gigabit Ethernet 2 interface is configured as trusted for DHCP snooping.
•
On the Gigabit Ethernet 3 interface, DHCP snooping is not enabled on the VLANs to which the
interface belongs.
