Christian, Sorry about not reading the IOS450E correctly. It is easier if when posting you remove the continuation numbers of the MLTWO.
Sometimes if you just nudge a connection ever so slightly then the point to point light is misaligned and one or both of the machines could not see it. So if the z10 was producing the messages that might mean that it was looking down the pipe to the other end and just not seeing it. It does not always mean that the z10 is the problem. Only that the z10 sees the problem. I also have a DWDM. One of two paths failed for my ETR. It took the CE several months to determine it was a bad card in the DWDM. Our z10 did not see an issue, our z9 saw the issue. And the error message were only on the z9 side. And we did everything. Replaced ficon, reset connections, checked the cisco router in the middle. And so forth. Still in my case, the CE had to replace cards in the DWDM one at a time on both sides before it was found. Hardware and cables can be delicate. It does not always take much of a mis-alignment for one side or the other to start producing IOS messages.
