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.
