Diagnostic ports
Diagnostic ports (D_Ports) are used for running diagnostics to isolate link level faults and inter-switch
link testing in fabric, optical, and remote loopback modes. The D_Port is not part of any fabric and it
does not carry any data or protocol traffic with it. It is used only for running diagnostic traffic for isolating
link level faults. The D_Port can be used to get estimated link distance measurements as done for long
distance mode links. For information on configuring a D_Port, refer to the Fabric OS Administrator's
Guide. Web Tools cannot configure a D_Port.
The following list of features is not supported when a port is configured as a D_Port:
• Port swap
• Port bind
• Port trunk
• QoS Enable/Disable
• BB credit
• NPIV Enable/Disable/Max login
• Allow/Prohibit Matrix
D_Ports do not take part in zoning. If a D_Port is added to a zone it does not take part in the fabric.

1. Click a port in the Switch View to open the Port Admin tab .
2. Click the FC Ports tab.

The Licensed column identifies the port license status:
• If the port has a license allocated, the Licensed field contains the value Yes.
• If the port does not have a license allocated and there are no free licenses that can be allocated,
the Licensed field contains the value No.
• If the port does not have a license allocated and there are licenses that can be allocated to the
port, the Licensed field contains the value Possible.
You can reserve or release a license on any port with a license allocated. You must be logged in as
Admin to reserve and release licenses.
NOTE
You must disable the port or switch before reserving or releasing a license.
To reserve a license, click Reserve License in the Port Admin tab.
