      disc - software discard network interface


      device disc


      The disc interface is a software discard mechanism which may be used for
      performance analysis and/or software testing.  As with other network
      interfaces, 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).
      inet(4), intro(4)


      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
      appeared in FreeBSD 5.0.


Based on BSD UNIX
FreeBSD is an advanced operating system for x86 compatible (including Pentium and Athlon), amd64 compatible (including Opteron, Athlon64, and EM64T), UltraSPARC, IA-64, PC-98 and ARM architectures. It is derived from BSD, the version of UNIX developed at the University of California, Berkeley. It is developed and maintained by a large team of individuals. Additional platforms are in various stages of development.
