portDPortTest
Initiates or terminates a D_Port test.
SYNOPSIS portdporttest --start [slot/]port_list
portdporttest --stop [slot/]port_list
portdporttest --show [slot/]port_list | all
portdporttest --help
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 16G SFPs capable of electrical loopback)
• An optical loopback test (supported only on 16G SFPs capable of optical loopback)
• A link traffic test
• A link distance measurement
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.
Test
For each sub-test, the command displays the Start time, test result (PASSED,
FAILED, RESPONDER, or IN PROGRESS), estimated time in seconds, and
diagnostic comments. Comments include the following:
No SFP or chip support
The test result is skipped because the SFP or port is not capable of D_Port
functionality.
See remote port results
The test result related to this comment is RESPONDER. The port is in responder
state and test results will be available at the initiator port on the remote side of the
link.
