The hme interface provides access to the 10Mb/s and 100Mb/s
via the National DP83840 Ethernet 10/100 Mb/s Physical
Layer or the
Quality QS6612 Ethernet MII Transceiver for Category 5
Twisted Pair Cable
chip sets. The hme is found on the SunSwift and Sun QuadFastEthernet
Each of the host's network addresses is specified at boot
time with an
SIOCSIFADDR ioctl(2). The hme interface employs the address
protocol described in arp(4) to dynamically map between Internet and Ethernet
addresses on the local network.
When a hme interface is brought up, by default, it will attempt to autonegotiate
the link speed and duplex. The speeds, in order
are: 100 Mb/s Full Duplex, 100 Mb/s Half Duplex, 10 Mb/s
Full Duplex, and
10 Mb/s Half Duplex.
The hme supports several media types, which are selected via
ifconfig(8) command. The supported media types are:
media autoselect Attempt to autoselect the media type
media 100baseTX mediaopt full-duplex
Use 100baseTX, full duplex
media 100baseTX mediaopt half-duplex
Use 100baseTX, half duplex
media 10baseT mediaopt full-duplex
Use 10baseT, full duplex
media 10baseT mediaopt half-duplex
Use 10baseT, half duplex
arp(4), be(4), ie(4), ifmedia(4), inet(4), intro(4), le(4),
qe(4), sbus(4), hostname.if(5), ifconfig(8)
OpenBSD support for the hme first appeared in OpenBSD 2.4.
The hme sbus cards will not function in a sun4c class machine, due to
OpenBSD 3.6 October 5, 2001
