Configuring an Ethernet interface to operate in promiscuous mode
An Ethernet interface usually receives only packets with matched destination MAC addresses. After you
configure an Ethernet interface to operate in promiscuous mode, however, the interface no longer checks
the MAC addresses in received packets. Rather, it receives all Ethernet packets with correct format. You
might need to configure a network listening port to operate in promiscuous mode.

Configuring a loopback interface
Introduction
A loopback interface is a virtual interface. The physical layer state of a loopback interface is always up
unless the loopback interface is manually shut down. A loopback interface is widely used in the following
scenarios:
