    • An Ethernet network device includes a port logic module that is associated with a device port of the Ethernet network device. A packet processing module includes an ingress processing module that receives an incoming packet and that generates a control traffic tag. An ingress command execution module receives the incoming packet and the control traffic tag, generates a duplicate packet that is identical to the incoming packet, and generates a device interface code that identifies the port logic module based on the control traffic tag. A control traffic routing module receives the duplicate packet and the device interface code and forwards the duplicate packet to the port logic module. A network traffic analysis device receives the duplicate packet. The port logic module replaces a first destination header of the duplicate packet with a second destination header that is identical to a destination header of the incoming packet.

    • Systems, methods, and other embodiments associated with controlling the flow of packets in a network are described. According to one embodiment, an apparatus includes a transceiver and a flow logic. The flow logic is configured to control the transceiver to transmit a frame to a downstream device by determining whether the frame matches a key value. The key value identifies a source of frames. The key value is part of a flow control rule that specifies an action to perform for frames received from the source that are to be transmitted to the downstream device. The flow logic is also configured to control the transceiver to transmit a frame to a downstream device by, in response to determining that the frame matches the key value, controlling transmission of the frame to the downstream device according to the action specified by the flow control rule.

    • A physical layer module (PHY) of a network device includes a control module and a cable-test module. The control module selectively generates a cable-test enable signal to test a cable including four pairs of twisted wire. The cable-test module tests the cable based on the cable-test enable signal. The cable-test module transmits test signals on the four pairs at a first time and receives return signals. The cable-test module determines that the cable is not faulty when the return signals received on first and second pairs of the four pairs have an amplitude less than a first predetermined amplitude, and when the return signals received on third and fourth pairs of the four pairs have an amplitude greater than a second predetermined amplitude and are received substantially contemporaneously.
