Q

What is a loopback test?

A

Test that sends data out of a nic and checks to see if it comes back. Software versions that dont test the actual port are commonly included in the devices own diagnostics. Physical loop test require loopback plug and will include port.

Q

What is a Loopback Plug?

A

Network connector that connects back into itself for physical loopback testing
