When you create the STM64/10GELAN service, the mode of ODU2 is different:

STM64/10GEWAN ODU2 standard mode
10GELAN ODU2E speedup mode

So when you create the client service with STM64, remember select the standard mode;

When you create the client service with 10GELAN, select the speedup mode; ---if this selection is wrong, there will be ODU2_LOFLOM alarm;

The solution to this issue:

1 check if the mode of ODU2 in the NS4 card is wrong

1) Check which ODU2 slot is used, then check the ODU2 mode in the WDM interface of this NS4 card, advanced attribute, check the mode of this ODU2 slot is speedup or standard;
2) For STM64 service ,it should be standard, for 10GELAN , should be speedup;

2 delete the wrong client and ODU2 trail ,then modify the ODU2 mode of this ODU2 timeslot basing related NS4;

3 reconfigure the client service and select the correct mode of ODU2;

Thanks

Thanks for your valuable information. I can add here more that it is also applicable in FOADM also. Actually it is not about ROADM or FOADM. It is related to service type and board you are using..

Thanks for your opinion.

Actually in both FOADM & ROADM technology this service trail creation works.
This is a common scenarion.
