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. The le interface employs the address resolution proto-
col 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.
