HBAs support testing in static and dynamic D_Port modes. If a D_Port is enabled on the switch, the
switch forces the connected adapter port into D_Port mode. As soon as the D_Port is enabled on a
switch, the HBA goes to dynamic D_Port mode, and then, the switch initiates tests on the HBA.
In dynamic D_Port mode, you can disable the physical port by using the bcu port --disable command
but bcu port --disable will not exit dynamic D_Port mode. When you enable the port again, the switch
will again force the adapter port into D_Port mode if the switch port is still enabled as a D_Port.
The following sections apply to
•
Using D_Port in on-demand mode

•
Enabling D_Port in static mode between a switch and an HBA
This procedure enables a D_Port diagnostic session from the connected switch to an HBA. After the
default test suite is run automatically, you can run specific tests manually to obtain additional detail.
1. Disable the switch port by using the portDisable command.
2. Configure the switch port that you want to enable as a D_Port by using the portCfgDport --enable
command.
3. Disable the adapter port by using the adapter bcu port --disable command.
4. Enable the switch port by using the portEnable command.
5. Enable the adapter port as a D_Port by using the adapter bcu diag --dportenable command and
configure test parameters.
For more details on adapter configuration, refer to the Brocade Adapters Administrator’s Guide.
6. Enable the switch port.
BCU D_Port commands
The following BCU commands can be used for D_Port configuration and control:
• bcu diag --dportenable -- Enables D_Port on a specific port, sets the test pattern, and sets the
frame count for testing.
• bcu diag --dportdisable -- Disables D_Port on a specific port and sets the port back to an N_Port or
NL_Port.
• bcu diag --dportshow -- Displays test results for a test in progress on a specific port.
• bcu diag --dportstart -- Restarts a test on a specific port when the test has completed.
• bcu port --list -- Displays the D_Port enabled or disabled state on the adapter and connected switch.
Limitations and considerations for D_Port with HBAs
Keep in mind the following limitations and considerations for D_Port configurations:
• D_Port is supported only on Brocade 16-Gbps HBA ports operating in HBA mode with a 16-Gbps
SFP+ on Brocade 16-Gbps switches running Fabric OS version 7.1 or later. In addition, the Brocade
adapter must be using driver version 3.2.0 or higher.
• D_Port is supported on non-Brocade 16-Gbps HBAs if you have a Fabric Vision license present on
the switch and if the HBA vendor has implemented the Brocade HBA D_Port support.
• D_Ports do not support a loop topology.
• D_Ports are not supported in a configuration of an HBA to another HBA (in target mode).
