Mike,
For GbE stuff we strongly recommend *AUTO *AUTO for speed and duplex on
both ends of the connection. With 10/100 stuff we still recommend forcing
speed and duplex on BOTH the switch and in i5/OS. If the switch is not GbE
capable then set both for the highest speed supported. But also VERIFY
that the switch AND i5/OS are reporting what you've requested.
Occasionally we DO see even with the settings forced that one side does
*FULL duplex and the other side does *HALF. In these cases settings for
*HALF on both ends seem the only way to get them to make nice. I don't
believe this is your problem at this point.
What is your setting for the CMNRCYLMT on the Ethernet line? If it is
set to (1 0) then the line will retry forever (a good thing) while if it's
anything else it will only try some for a while and then go FAILED. With
the (1 0) Setting it does appear to magically heal itself. Frankly I
think your network guys did 'something' but how can you prove that?

RE: NIC in FAILED status
It is the standard NIC in a 520. Will run at 1GB and shows that it is
connected at 1GB right now. Connected to a Cisco switch (not sure of the
model). Cisco admin says his side was set to auto also (although I have
read that switch ports should not be set to auto, our switch admins insist
it is "best practice" to set auto on all ports). 520's come standard with
a pair of copper nics and one was working when the second one was not.

What is the NIC on the iSeries? Can it run at 1GB? What is the switch
that is was plugged in to? Was it set at 1GB FDX and the iSeries NIC is
older and can only run at 100MB FDX or less?
