(I sent this to comp.unix.osf.osf1, but it may be more
appropriate here)
I've just turned auto-negotiation on on the ethernet interface on
our DS20 (OSF1 kandinsky V4.0 1229 alpha):
Jun 27 15:03:15 kandinsky vmunix: tu0: DECchip 21140: Revision:
2.2
Jun 27 15:03:15 kandinsky vmunix: tu0: auto negotiation capable
device
Jun 27 15:03:15 kandinsky vmunix: tu0 at pci2001 slot 2
Jun 27 15:03:15 kandinsky vmunix: tu0: DEC TULIP (10/100)
Ethernet Interface, hardware address: 00-06-2B-01-29-A1
Jun 27 15:03:15 kandinsky vmunix: tu0: auto negotiation on: will
advertise 100BaseTX (UTP) port: full duplex
previously, it seemed that by default auto-negotiation was off
aand the default settings of the card meant that it ran at
10MBits/s.
This change fixed this sort of. Now the card runs at 100MBits/s
but periodically resets itself (every minute or so):
Jun 27 17:37:26 kandinsky vmunix: tu0: link down
Jun 27 17:37:30 kandinsky vmunix: tu0: link up: negotiated
100BaseTX: full duplex
Jun 27 17:38:32 kandinsky vmunix: tu0: link down
Jun 27 17:38:35 kandinsky vmunix: tu0: link up: negotiated
100BaseTX: full duplex
Jun 27 17:39:53 kandinsky vmunix: tu0: link down
Jun 27 17:39:57 kandinsky vmunix: tu0: link up: negotiated
100BaseTX: full duplex
Jun 27 17:44:17 kandinsky vmunix: tu0: link down
Jun 27 17:44:20 kandinsky vmunix: tu0: link up: negotiated
100BaseTX: full duplex
As you can see there is nothing regular in the way this error
occurs but in gerneral the link usually stays up for around
1 to 1 1/2 minutes before going down. I've played around with
cables and ports but to no avail.
Anybody have a clue as to what may be going wrong? All our
other boxes are correctly coperating at 100MB/s (including our
ES40 with a similar NIC).
Thanks,
