uni-directional ethernet link with intel 82599 10 GbE Controller, help.

[alireza11048]

Hi,

I am trying to establish a uni-directional Ethernet link where a singular fiber is used to transmit data to the receiver where both sides use ixgbe as driver. The Rx of the transmit side and the Tx of the receive side are not physically connected, like in a Data diode scenario.

To force links state to UP(as soon as I detach the TX line from one side, both side link status goes DOWN), i set FLU bit in AUTOC register and also i set the speed with LMS bits in the AUTOC register.

Links successfully become in up state, but I can not receive UDP packets that are sent from the TX side on the RX side.

Any advice to solve the problem in this mode is appreciated.
