This example shows how to stop IPSG with static hosts on an interface.
Switch(config-if)# no ip verify source
Switch(config-if)# no ip device tracking max
This example shows how to enable IPSG with static hosts on a port.
Switch(config)# ip device tracking
Switch(config)# ip device tracking max 10
Switch(config-if)# ip verify source tracking port-security
This example shows how to enable IPSG for static hosts with IP filters on a Layer 2 access port and to verify the valid IP
bindings on the interface Gi1/0/3:
Switch# configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
Switch(config)# ip device tracking
Switch(config)# interface gigabitethernet1/0/3
Switch(config-if)# switchport mode access
Switch(config-if)# switchport access vlan 10
Switch(config-if)# ip device tracking maximum 5
Switch(config-if)# ip verify source tracking
Switch(config-if)# end
Switch# show ip verify source

This example shows how to enable IPSG for static hosts with IP-MAC filters on a Layer 2 access port, to verify the valid IP-MAC
bindings on the interface Gi1/0/3, and to verify that the number of bindings on this interface has reached the maximum:
Switch# configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
Switch(config)# ip device tracking
Switch(config)# interface gigabitethernet1/0/3
Switch(config-if)# switchport mode access
Switch(config-if)# switchport access vlan 1
Switch(config-if)# ip device tracking maximum 5
Switch(config-if)# switchport port-security
Switch(config-if)# switchport port-security maximum 5
Switch(config-if)# ip verify source tracking port-security
Switch(config-if)# end
Switch# show ip verify source

This example displays all IP or MAC binding entries for all interfaces. The CLI displays all active as well as inactive entries.
When a host is learned on a interface, the new entry is marked as active. When the same host is disconnected from that interface
and connected to a different interface, a new IP or MAC binding entry displays as active as soon as the host is detected.
The old entry for this host on the previous interface is marked as INACTIVE.
