Displaying IP Source Guard Information
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
IP Device Tracking Probe Interval = 30
