Chapter 53 Configuring DHCP Snooping, IP Source Guard, and IPSG for Static Hosts
Configuring IP Source Guard for Static Hosts
The following example displays all IP-to-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 the current interface and connected to a different interface, a
new IP-to-MAC binding entry is displayed as active as soon as the host is detected. The old entry for this
host on the previous interface is now marked as inactive.

The following example displays all inactive IP-to-MAC binding entries for all interfaces. The host was
first learned on GigabitEthernet 3/1 then moved to GigabitEthernet 4/1. The IP-to-MAC binding entries
learned on GigabitEthernet 3/1 are marked as inactive.
