200.1.1.7 0001.0600.0000 8 GigabitEthernet1/0/1 INACTIVE
This example displays all active IP or MAC binding entries for all interfaces:
Switch# show ip device tracking all active
IP Device Tracking = Enabled
IP Device Tracking Probe Count = 3
IP Device Tracking Probe Interval = 30

200.1.1.5 0001.0600.0000 9 GigabitEthernet1/0/1 ACTIVE
This example displays all inactive IP or MAC binding entries for all interfaces. The host was first learned
on GigabitEthernet 1/0/1 and then moved to GigabitEthernet 0/2. the IP or MAC binding entries learned
on GigabitEthernet1/ 0/1 are marked as inactive.
Switch# show ip device tracking all inactive

Configuring IP Source Guard for Static Hosts on a Private VLAN Host Port
Note You must globally configure the ip device tracking maximum limit-number interface configuration
command globally for IPSG for static hosts to work. If you only configure this command on a port
without enabling IP device tracking globally or setting an IP device tracking maximum on that interface,
IPSG with static hosts will reject all the IP traffic from that interface. This requirement also applies to
IPSG with static hosts on a Layer 2 access port.
