.Sh DESCRIPTION
|
||||
The
|
||||
.Nm
|
||||
interface provides access to the 10 Mb/s
|
||||
.Tn Ethernet
|
||||
network via the
|
||||
.Tn AMD
|
||||
Am7990
|
||||
Local Area Network Controller for Ethernet
|
||||
.Pq Tn LANCE
|
||||
chip set.
|
||||
.Pp
|
||||
Each of the host's network addresses
|
||||
is specified at boot time with an
|
||||
.Dv SIOCSIFADDR
|
||||
.Xr ioctl .
|
||||
The
|
||||
.Nm
|
||||
interface employs the address resolution protocol described in
|
||||
.Xr arp 4
|
||||
to dynamically map between Internet and
|
||||
.Tn Ethernet
|
||||
addresses on the local
|
||||
network.
|
||||
.Pp
|
||||
Interfaces attached to an
|
||||
.Sy ledma0
|
||||
typically have have two types of connectors:
|
||||
.Pp
|
||||
.Bl -tag -offset indent -width xxxxxxxxxxxxxxxxxx
|
||||
.It AUI/DIX
|
||||
Standard 15 pin connector
|
||||
.It 10BaseT
|
||||
UTP, also known as twisted pair
|
||||
.El
|
||||
.Pp
|
||||
The appropriate connector can be selected by supplying a
|
||||
.Cm media
|
||||
parameter to
|
||||
.Xr ifconfig 8 .
|
||||
The supported arguments for
|
||||
.Cm media
|
||||
are:
|
||||
.Bl -tag -offset indent -width xxxxxxxxxxxxxxxxxx
|
||||
.It Sy 10base5/AUI
|
||||
to select the AUI connector, or
|
||||
.It Sy 10baseT/UTP
|
||||
to select the UTP connector.
|
||||
.El
|
||||
.Pp
|
||||
If a
|
||||
.Cm media
|
||||
parameter is not specified, a default connector is selected for
|
||||
use by examining all media types for carrier.
|
||||
The first connector on which a carrier is detected will be selected.
|
||||
Additionally, if carrier is dropped on a port, the driver will switch between
|
||||
the possible ports until one with carrier is found.
