DESCRIPTION    [Toc]    [Back]

     The le interface provides access to  the  10  Mb/s  Ethernet
network via the
     AMD  Am7990  Local  Area  Network  Controller  for  Ethernet
(LANCE) chip set.

     Each of the host's network addresses is  specified  at  boot
time with an
     SIOCSIFADDR  ioctl(2).  The le interface employs the address
resolution
     protocol described in arp(4) to dynamically map between  Internet and
     Ethernet addresses on the local network.

     Different cards and machines have different kinds of connectors, as follows:


     AUI/DIX           Standard 15 pin connector

     10BaseT           UTP, also known as twisted pair

     By default, the system will select the media type  automatically, but the
     ifconfig(8)  command  can  be used to force the media selection.  The media
     types are shown below:

     media autoselect  Attempt to autoselect the media type  (default)

     media 10base5     Use the AUI connector

     media 10baseT     Use the twisted pair connector

NOTES    [Toc]    [Back]

     Some  sbus  models, in particular the 501-1450 and 501-1881,
have dip
     switches which must be changed to select between the BNC and
AUI modes.
     For  BNC,  set 1-6 ON, 7-8 OFF; for AUI set 1-6 OFF, and 7-8
ON.
