BE(4)							   BSD Kernel Interfaces Manual 						     BE(4)

NAME

     be -- SPARC Fast Ethernet interface

SYNOPSIS

     qec* at sbus? slot ? offset ?
     be* at qec?

DESCRIPTION

     The be interface provides access to the 10Mb/s and 100Mb/s (half duplex only) Ethernet networks.  The be is found on the Sun 10/100 Mbit Eth-
     ernet boards (Sun part number SUNW,501-2450).

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

     The be is not capable of link autonegotiation, so a media type must be specified with ifconfig(8).  The supported media types are:

	   media 100baseTX
		       Use 100Mbps, half duplex

	   media 10baseT
		       Use 10Mbps, half duplex

SEE ALSO

     arp(4), ifmedia(4), inet(4), intro(4), netintro(4), sbus(4), ifconfig(8)

HISTORY

     Support for the be first appeared in NetBSD 1.4.
