LE(4)

NAME
le - SPARC AMD 7990 LANCE ethernet interface

SYNOPSIS
le* at sbus? slot ? offset ?
le* at ledma0 slot ? offset ?
le* at lebuffer? slot ? offset ?

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 protocol described in arp(4) to dynamically map between Internet and Ethernet addresses on the local network.

Interfaces attached to an ledma0 typically have have two types of connectors:

AUI/DIX
    Standard 15 pin connector

10BaseT
    UTP, also known as twisted pair

The appropriate connector can be selected by supplying a media parameter to ifconfig(8). The supported arguments for media are:

10base5/AUI
    to select the AUI connector, or

10baseT/UTP
    to select the UTP connector.

If a 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.
