Thank you for your support.

seem the lab is bug. I don't certainly. I have to connect the link before I start device such I can configure port channel to success.

Yes it sure bug' I face the same in my lab exactly same 

N9k refused up po' but I found if I config spt mst the issue is solve.

Do show spanning tree you will see that PO and port members is missing from spanning tree table!! 

Thank you for your useful information
