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 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).
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 appeared in
FreeBSD
5.0.
