I think it might have had something to do with a node used "broadcast" instead of LACP.
I think that because whichever switch ports I connected the node to those ports would go adminDown after a short wile.
I'll take more time to find if that was the root cause.
(node being Centos with net team device spanning two SPF+ ports(dual port NIC))
Would/should switch behave this way is such a situation?
