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, itвЂ™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 вЂњloopbackвЂќ 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.

Д®ven though the name вЂњself-loopbackвЂќ 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.
