Hi@ster
According to the error message, it should be "This interface board does not support this command."
For S9300 and S9300X series switches, only B series cards, E series cards (except LE2D2X48SEC0 card), and X series cards support NetStream.
Because the interface board LE0DX16SFC00 belongs to the F series of boards, it does not support the Netstream function.
