Checking the WDM Interface in one LOG board, it was detected that in one first query, laser status was showed as Open but in a second query it was showed as closed. This parameter was continously changing.
By Navigator (using :cfg-get-laser) happened the same.
This scenario was in all non-used LOG borad ports.
Disable the LPT function in non-used ports.
This is due to LPT function is enabled:
LPT is an function to configure when the client port has already been connected with customer's router that is working well. LPT is a function that when the customer's router does not work, huawei WDM OTU board stop the Tx/Rx port,
then let the customer's router switch automatically.
This is not a problem, it is a normal function.
