DESCRIPTION
The
ie
interface provides access to a 10 Mb/s Ethernet network
through a controller using the Intel 82586
LAN
Coprocessor chip.
For a general description of network interfaces see
if.4n
ie0
specifies a
CPU-board-resident
interface, except on a Sun-3E where
ie0
is the Sun-3/E Ethernet expansion board.
ie1
specifies a
Multibus Intel Ethernet interface for use with a
VME
adapter.
ie2
and
ie3
specify
SunNet Ethernet/VME Controllers,
also known as a
Sun-3/E Ethernet expansion boards.

DIAGNOSTICS
There are too many driver messages to list them all individually here.
Some of the more common messages and their meanings follow.
- ie%d: Ethernet jammed
-
Network activity has become so intense that sixteen
successive transmission attempts failed,
and the 82586 gave up on the current packet.
Another possible cause of this message is a noise source
somewhere in the network,
such as a loose transceiver connection.
- ie%d: no carrier
-
The 82586 has lost input to its carrier detect pin
while trying to transmit a packet,
causing the packet to be dropped.
Possible causes include an open circuit somewhere in the network
and noise on the carrier detect line from the transceiver.
- ie%d: lost interrupt: resetting
-
The driver and 82586 chip have lost synchronization with each other.
The driver recovers by resetting itself and the chip.
- ie%d: iebark reset
-
The 82586 failed to complete
a watchdog timeout command in the allotted time.
The driver recovers by resetting itself and the chip.
- ie%d: WARNING: requeuing
-
The driver has run out of resources while getting a packet
ready to transmit.
The packet is put back on the output queue for retransmission
after more resources become available.
- ie%d: panic: scb overwritten
-
The driver has discovered that memory that should remain
unchanged after initialization has become corrupted.
This error usually is a symptom of a bad 82586 chip.
- ie%d: giant packet
-
Provided that all stations on the Ethernet are operating
according to the Ethernet specification, this error ``should
never happen,'' since the driver allocates its receive buffers
to be large enough to hold packets of the largest permitted size.
The most likely cause of this message is that some other station
on the net is transmitting packets whose lengths exceed the maximum
permitted for Ethernet.
