show ip verify source
• The following output appears when you enter the show ip verify source interface fa6/4 command
and the interface fa6/4 has IP source filter mode configured as IP MAC, and existing IP MAC that
binds 10.0.0.2/aaaa.bbbb.cccc on VLAN 10 and 11.0.0.1/aaaa.bbbb.cccd on VLAN 11 :
Interface Filter-type Filter-mode IP-address Mac-address Vlan
--------- ----------- ----------- --------------- -------------- ---------
fa6/4 ip-mac active 10.0.0.2 aaaa.bbbb.cccc 10
fa6/4 ip-mac active 11.0.0.1 aaaa.bbbb.cccd 11
fa6/4 ip-mac active deny-all deny-all 12-20
• The following output appears when you enter the show ip verify source interface fa6/5 command
and the interface fa6/5 has IP source filter mode configured as IP MAC, and existing IP MAC
binding 10.0.0.3/aaaa.bbbb.ccce on vlan 10, but port security is not enabled 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.
• The following 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 configured:
DHCP security is not configured on the interface fa6/6.
This example shows how to display all interfaces on the switch that have DHCP snooping security
enabled with the show ip verify source command.
The output is an accumulation of per-interface show CLIs:
Interface Filter-type Filter-mode IP-address Mac-address Vlan
--------- ----------- ----------- --------------- -------------- ---------
fa6/1 ip active 10.0.0.1 10
fa6/1 ip active deny-all 11-20
fa6/2 ip inactive-trust-port
fa6/3 ip inactive-no-snooping-vlan
fa6/4 ip-mac active 10.0.0.2 aaaa.bbbb.cccc 10
fa6/4 ip-mac active 11.0.0.1 aaaa.bbbb.cccd 11
fa6/4 ip-mac active deny-all deny-all 12-20
fa6/5 ip-mac active 10.0.0.3 permit-all 10
