DISC(4)			 BSD Kernel Interfaces Manual		       DISC(4)

NAME
     disc -- software discard network interface

SYNOPSIS
     device disc

DESCRIPTION
     The disc interface	is a software discard mechanism	which may be used for
     performance analysis and/or software testing.  As with other network in-
     terfaces, the discard interface must have network addresses assigned for
     each address family with which it is to be	used.  These addresses may be
     set or changed with the SIOCSIFADDR ioctl(2).

     Each disc interface is created at runtime using interface cloning.	 This
     is	most easily done with the ifconfig(8) create command or	using the
     cloned_interfaces variable	in rc.conf(5).

SEE ALSO
     inet(4), intro(4)

HISTORY
     The disc device appears to	have been derived from the lo(4) device	around
     the time of 4.4BSD.  This manpage was adapted from	lo(4) and first	ap-
     peared in FreeBSD 5.0.
