OneConnect Loopback Test Combinations
Run the following loopback test combinations using the appropriate checkboxes:
DMA Loopback Test – The DMA loopback test sends data from the host to the
adapter, then back to the host, where it is checked for data miscompute errors.
All tests except the DMA loopback test are run on the currently selected port.
The DMA loopback test is run across the entire adapter. The same diagnostic is
therefore executed regardless of the currently selected physical port. Also,
unlike other diagnostics, this test affects the operation of all ports on the
adapter. (Not available on ESXi systems.)
PHY Loopback Test – The PHY loopback test connects the transmit output of
the physical layer to the receive input of the physical layer. The data is
transmitted, received and checked for data miscompute errors.
External Loopback Test – A diagnostic test in which a random data pattern is
sent down to an adapter link port. The data goes out the port and immediately
returns via a loopback connector. The returned data is subsequently validated
for integrity.
