DESCRIPTION Use this command to manually terminate or re-initiate testing on a diagnostic port (D_Port). 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 SFPs capable of electrical loopback)
• An optical loopback test (supported only on 16Gb 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:
Port
The port number on the local side of the link
Remote WWN
The world wide node name of the switch on the remote side of the link.
Remote Port
The port number on the remote side of the link
Start time
Date and time of test start
End time
Date and time of test completion
Status
On the link initiator, this field displays the overall test status as PASSED, FAILED,
SKIPPED, or NOT STARTED (test in progress). On the link responder, the status
displays PASSED, FAILED, or RESPONDER.
