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.
