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.

This example displays all inactive IP or MAC binding entries for all interfaces. The host was first learned
on GigabitEthernet 0/1 and then moved to GigabitEthernet 0/2. the IP or MAC binding entries learned
on GigabitEthernet 0/1 are marked as inactive.
Switch# show ip device tracking all inactive
IP Device Tracking = Enabled
IP Device Tracking Probe Count = 3
