Brocade Fabric OS Administrators Guide (Supporting Fabric OS v7.3.0) - Manual (Page 436)

You can display the complete results from either the responder or the initiator switch. If the initiator
switch is running Fabric OS v7.1.x or earlier, the responder displays only the local D_Port results, and
you must query the initiator to see the complete results.
The following example shows the D_Port results.
switch:admin> portdporttest --show 26
D-Port Information:
===================
Port: 26
Remote WWNN: 10:00:00:05:33:13:2f:b5
Remote port index: 42
Mode: Automatic
Start time: Wed Feb 2 01:41:43 2011
End time: Wed Feb 2 01:43:23 2011
Status: PASSED
================================================================================
Test Start time Result EST(secs) Comments
================================================================================
Electrical loopback 01:42:08 PASSED -- ----------
Optical loopback 01:42:16 PASSED -- ----------
Link traffic test 01:43:15 PASSED -- ----------
================================================================================
Roundtrip link latency: 1108 nano-seconds
Estimated cable distance: 20 meters
Buffers required: 1 (for 1024 byte frames at 16Gbps speed)
The following example shows the portdporttest --show output where the electrical and optical tests
pass but the link test fails.
switch:admin> portdporttest --show 26

Use the portDportTest --show all command to display the capabilities and test results of all the
D_Ports in a switch.
