portdporttest --help

Description Use this command to manually terminate, re-initiate test, or stop test on a diagnostic port (D_Port). The

portdporttest --show command displays the result of the D_Port tests. The port must be configured as a D_Port

and physically connected to a second D_Port on a remote switch. Refer to the portCfgDPort command for more

information. The portdporttest --start command only needs to be issued on one end of the link.

The D_Port test performs the following diagnostics:

• An electrical loopback test (supported only on 16Gb and 32Gb SFPs capable of electrical loopback)

• An optical loopback test (supported only on 16Gb and 32Gb SFPs capable of optical loopback)

• A link traffic test

• A link distance measurement

Use the --setarg option to set the test parameters and exit. Use the --restart option to restart the test with the

already configured parameters.

Use the --show option with a port operand to display the test status for the specified ports at any time during the

test or after the diagnostics has completed. The command output includes the following information for each

configured D_Port:

Slot

The slot number on the local side of the link.

Port

The port number on the local side of the link

Remote WWNN

The world wide node name of the switch on the remote side of the link.

Remote WWPN

The world wide port name of the Host Bus Adapter (HBA) or device port on the remote side

of the link.
