For a physical interface device to function, you must configure at least one logical
interface on that device. For each logical interface, you must specify the protocol
family that the interface supports. You can also configure other logical interface
properties. These vary by Physical Interface Card (PIC) and encapsulation type, but
include the IP address of the interface, and whether the interface supports multicast
traffic, data-link connection identifiers (DLCIs), virtual channel identifiers (VCIs) and
virtual path identifiers (VPIs), and traffic shaping.
