Troubleshooting with a Diagnostic Port (D_Port)
Use the D_Port (diagnostic port) feature on the QLogic 2700 Series Adapters to
identify and isolate link failures resulting from faulty modules (link, cable, or SFP)
by running diagnostics over a Fibre Channel link.
The D_Port feature is supported on Windows, Linux, and ESXi.
D_Port can be run only in dynamic mode; it does not support static mode.
D_Port requires a Fibre Channel Adapter that is linked to a Brocade Fibre
Channel 16G or 32G switch, the supported Brocade 16G or 32G Fibre Channel
switch firmware, and a Brocade Fibre Channel switch feature license (Fabric
Vision™).
Configure the diagnostic D_Port on the Brocade switch to dynamically allow a port
to enter D_Port mode when a D_Port is configured on the switch end, and then
return to operational mode when the test is completed. Also configure the switch
to start and stop the diagnostic test on the adapter port. See the Brocade switch
documentation for details.
