     le0 at ledma0                            (sun4m onboard)
     le0 at obio0 addr 0xf9000000 level 6     (sun4/300)

DESCRIPTION
     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 fol-
     lows:

     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
     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.
