Hi again managers,
You may recall that I posted a few weeks ago asking about ethernet
address checksum errors. Well, I got a few responses back. The most
intreging answer was from Dr. Blinn at DEC. First, Jorge Pizarro L.
asked if I had PATCH ID: OSF375-048. I did. Ian Thurlbeck asked if
I had recently upgraded the OS. I had not.
Dr Blinn from DEC talked to a few engineers and it seems that
there may be some sort of design problem with the sytem. He
has asked that I have the problem escalated so that they can work
on a engineering solution to the problem. A quick quote from Dr Blinn:
:Getting a formal problem report in the system will allow our engineers to
:try to fix the problem; so far, we just don't have enough instances of any
:problem to be sure there's cause for in-depth investigation.
I am attempting to get the problem escalated right now...it is a little
slow going.
I would like to ask all the managers with 4100s to do the following
simple test:
grep checksum /var/adm/messages
Please mail me the results if you find that you are encountering the same
problem. It would help if you could give me a little info about your
system such as what type network interfaces you are using. I would like
to have as much data to give to DEC as possible.
My original message is at the bottom.
Thanks,

Hi managers,
Another unusual problem for you all today. I have a pair of 4100s
each with 3 DE500-XA ethernet cards in them. I am using DU 3.2g as the
os, and upgrading to 4.0x is not presently an option.
Occasionally, when booting, we will get a report that one of the
ethernet cards has an "ethernet address checksum error". The first time
this happened we replaced the card in question. The problem still
happens on occasion. Rebooting will invariably fix the problem. One
host has had the problem 6 times, the other has only had it happen once.
When we get this message, the interface is disabled, and is not useable.
Interfaces 0 and 1 are plugged into a Cabletron Hub, while interface 3
is in a DEChub900.
Here are the entries on Jetsam:
jetsam.latrade.com # grep checksum messages
Jan 22 13:40:00 jetsam vmunix: tu2: ethernet address checksum error
Jan 27 00:11:45 jetsam vmunix: tu1: ethernet address checksum error
Jan 29 14:25:25 jetsam vmunix: tu2: ethernet address checksum error
Feb 12 10:21:54 jetsam vmunix: tu1: ethernet address checksum error
Mar 28 22:33:26 jetsam vmunix: tu0: ethernet address checksum error
Mar 31 09:45:58 jetsam vmunix: tu0: ethernet address checksum error
and here is the one entry on Flotsam:
flotsam.latrade.com # grep checksum messages
Feb 12 10:52:32 flotsam vmunix: tu2: ethernet address checksum error
I would be intrested to see the results of a similar grep on other
machines with a similar setup. I would also like to know if anybody has
any ideas as to what causes this, what patches might be available.
DEC is willing to replace the cards each time this happens, but I
suspect that this is happening too frequently to be defective cards.
I will, of course, summerize.
Thanks,
-cliff
