Hello,Steven:
Thanks for your help. There are some other questions.As for the old optics(10070H) that you told, the model type is 10/100/1000base -T copper.These transceivers havn't the DDMI function,so we can't observe the information of DDMI.
But the type of 10050H is SFP SX,It supports the DDMI. so the DDMI information should be supported by X670/X670V,but they didn't as well.
the picture shows the transceiver which I use now,are there something wrong Thanks for your help again.
