• This output appears when you enter the show ip verify source interface fa6/5 command and the
interface fa6/5 has IP source filter mode that is configured as IP MAC and existing IP MAC binding
10.0.0.3/aaaa.bbbb.ccce on VLAN 10, but port security is not en abled on fa6/5:
Interface Filter-type Filter-mode IP-address Mac-address Vlan
--------- ----------- ----------- --------------- -------------- ---------
fa6/5 ip-mac active 10.0.0.3 permit-all 10
fa6/5 ip-mac active deny-all permit-all 11-20
Note Enable port security first because the DHCP security MAC filter cannot apply to the port or
VLAN.
• This output appears when you enter the show ip verify source interface fa6/6 command and the
interface fa6/6 does not have IP source filter mode that is configured:
DHCP security is not configured on the interface fa6/6.
This example shows how to display all the interfaces on the switch that have DHCP snooping security
and IP Port Security tracking enabled with the show ip verify source command.
