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 Ethernet 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


Support for the be first appeared in NetBSD 1.4.
