![]() If a loopback test fails, it might indicate of failing hardware. By running and passing a loopback test, a person can identify if the device can send and receive data. First I thought my cable was simply badly made but I tried 3 times making new cables and all of them have the same result so I don't think it's a badly made cable. A loopback test eliminates superfluous connections and confirms that a transceiver or port is functioning properly by connecting the transmitter and. With a test, a loopback test is one or more signals sent from a device that is looped back (returned) to the same device. Send some udp packets at maximum throughput. So my question is how can I make this work? I simply want to start testing the interface. ![]() TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0 My other network interface do not seem to interfere: λ ifconfig A loopback test is the process of sending digital data streams from a source back to the same point without any intentional modifications. I can sporadically ping myself: λ ping 192.168.1.50 Link negotiation: Tried both auto and manual which didn't seem to make a difference.I configured the network interface as follows: And in Linux I sporadically see a link being established at 10mbit for a short amount of time. Now when I plug this cable into a network port I do see the lights coming on. ![]() So I build my own loopback cable with the following pinout: ![]() So I looked online and this seemed possible. ANd just see if I can send data and receive what I send. Since I don't want to setup two machines and run software on both the test connection my first thought was to create a loopback cable. The ROCA™ series from Complete Connect offers a robust solution for all outdoor applications including broadcast, concert and sporting events.So I need to create a simple process to test a large amount of gigabit network ports. Available in over 50 cable combinations and built using ultra-rugged & flexible cables combined with steel IP 67 connectors. Rugged, tough and perfectly suited for outdoor applications.
