PCI loopback test

Use BCU commands or HCM to perform a PCI loopback test for a specific port. In this test, a data

pattern is sent from the host to adapter firmware through the PCI bus. The returned data is

validated to determine PCI operation.

NOTE

You need to disable the port before you run loopback tests.

Performing PCI loopback tests through BCU

Use the diag --pciloopback BCU command to perform a PCI loopback test.

diag --pciloopback <port_id> [-p <pattern>] [-c <frame_count>]

where:

port_id ID of the port from which you want to run the test.

pattern Specifies the data test pattern. Must be at least one hexadecimal word.

frame count Specifies the frame count as an integer from 0 to 4,294,967,295.
