NMS version is T2000 V1R5, we have configured 2 equipments OSN 3500 equipped with N1SL16 card. Now we want to make the fiber connections between them through NMS but in the process of doing so it is showing errors.
NULL, just that the line board was showing no optical port free for creating the fiber connectuons.
we checked for all the probable causes and then finally we checked the particular slot where we right clicked on the port and a option came as ADD PORT where we decided the STM bandwidth and the port name.
after that when we did the same operation we were able to make fiber connections. and this time source and sink port cards weree shown green this means the ports are free and can be used.
The cause of the failure of folowing operation failure could be.
1 The particular port is already occupied this might be the reason we are not able to use this port.
2 The port is diabled or not configured
It is required to add all the ports in some cards before strating the fiber connectivity work on NMS. Because in some cards it comes by default and some cars we have to add.
