You might as well use a loopback cable into your Macs headphone jack, this would do the same function as the App Soundflower. You will use it to redirect the system audio to Audacity. Soundflower is a program that will route the system sounds to other apps.

At the end, we put a heat shrink tubing around it to prevent any short circuits. For example, you can complement Audacity by using other program like Soundflower. In this case we used an old Ethernet Cable, removed the cable isolation coat and connected the wires as described above. In this case, you need to connect two more wire pairs: pin 1 pin 3Īn example of a self-made self-loopback cable: Those are used to test interface rx/tx operations on GigabitEthernet (1gbit/sec) interfaces. If you want to use your plug on appliances from other manufacturers too, that maybe need a higher throughput during testing, it may be needed to create an eight pin self-loopback plug. This is the simpliest version of a four pin self-loopback plug which is used to test interface rx/tx operations on FastEthernet (100mbit/sec) interfaces. In the case of the FortiGate HQIP test, it’s already enough to connect the following conductor wires: pin 1 pin 3 You just need a RJ45 connector or an Ethernet cable with a RJ45 connector attached. It is very easy to create a self-loopback cable or connector plug by yourself. In comparison to normal “loopback” links, where one NIC is connected with another NIC on the same appliance, the self-loopback does realize the loopback inside the same NIC. Those cables are often descibed as selfloop or interface test cables. Įven though the name “self-loopback” is for some people a bit confusing, this is a very common and standardized wiring method for testing copper based ethernet equipment. Please restore factory reset or use port mode to perform the test WARNING: This test can only pass with factory configurations. This request looks like the following CLI output: Network Interface Loopback Test - Please connect ethernet cables: On some FortiGate models, you are being asked to connect a self-loopback cable on some ports during the HQIP test.
