Good afternoon, English is not my native language, I apologize for the mistakes. Used equipment Ciena 6110, 6130 with expansion cards L2PA1G2, L2PA622M. I try to configure the data transfer, could you explain to me the errors in the screenshots, in which cases they arise and how to fix them? The devices are connected serially, like so:
KS-15 --------DOMB--------KIEM--------ADAM
I'll try to clarify my question.
  1. The screenshots show the "Tx \ Rx Control" and "Tx \ Rx Channel MST" fields. What is the purpose of these fields? What is "MST"? What are the values in which cases they are displayed?
  2. What does the "FAIL" value mean in the "Tx \ Rx Channel MST" fields? In what cases does it appear?
  3. What does the "EOS" value mean in the "Tx \ Rx Control" fields? In what cases does it appear?
  4. What does "DNU" mean in the "Tx Control" field? In what cases does it appear?
