DESCRIPTION

The ie interface provides access to a 10 Mb/s Ethernet network through the Intel 82586 controller chip. For a general description of network interfaces see if(4N).

In the synopsis—Sun-3 lines above, the first line specifies the first, CPU board-resident, Intel Ethernet interface; the second line specifies a second Intel interface present on a Sun Ethernet board.

In the synopsis—Sun-2 lines above, the first line specifies the first Intel Ethernet controller on a Sun-2/50 or Sun-2/160; the second line specifies the first Intel Ethernet controller on a Sun-2/120 or Sun-2/170.

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, causing the 82586 to give 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 alloted time. The driver recovers by resetting itself and the chip.

ie%d: WARNING: requeueing
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.
