1. Search for fiber connections of certain optical interface boards on the OptiX OSN 3500 on site. It is found that the fiber connections of the optical interface boards can be displayed normally.
2. Analyze logs of the T2000. It is found that the T2000 returns a timeout event 30s later without waiting for the OptiX OSN 3500 to return data after issuing a command for searching for fiber connections.
3. When the OptiX OSN equipment is interconnected to old equipment, the fiber searching function requires the cooperation of the T2000, old equipment, and OptiX OSN equipment. In addition, the T2000 delivers configurations to optical interfaces one after another, and thus at least 600 ms is required for the T2000 to search for fiber connections each time. If an NE contains a large number of optical interfaces, the T2000 reports a timeout event due to very long searching time.The fiber searching function is optimized on the OptiX OSN equipment of V100R
