How to enable the an NIC to transmit data received from a port through the other port?

[QWu001]

I have purchased a network interface controller, with two optical fiber interface and one PCI interface. I plan to test its performance through a device produced by Spirent. This process requires to configure the NIC so that one of its ports can transmit data received from a port through the other port. However, I do not know how to do it. The operating system I am using is Linux. I would be grateful if you guys could help me with that!
