Displaying IP Source Guard Information
To disable IP source guard with source IP address filtering, use the no ip verify source interface
configuration command.
To delete a static IP source binding entry, use the no ip source global configuration command.
This example shows how to enable IP source guard with source IP and MAC filtering on VLANs 10
and 11:
Switch#
configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
Switch(config)#
interface gigabitethernet1/0/1
Switch(config-if)#
ip verify source port-security
Switch(config-if)#
exit
Switch(config)#
ip source binding 0100.0022.0010 vlan 10 10.0.0.2 interface
gigabitethernet1/0/1
Switch(config)#
ip source binding 0100.0230.0002 vlan 11 10.0.0.4 interface
gigabitethernet1/0/1
Switch(config)#
end
