Diagnostic Port (D_Port)

Topology 4: HBA to switch
Figure 8 illustrates connectivity between an HBA and a switch. F represents an F_Port to be
configured as a D_Port. This topology supports dynamic D_Port mode. In dynamic mode, the HBA
port does not need to be configured explicitly as a D_Port. It comes up in D_Port mode if the
corresponding switch port has been configured as a D_Port.
NOTE
In this topology, D_Port is supported only on Brocade 16-Gbps HBA (Brocade Fabric Adapter 1860)
ports operating in HBA mode with a 16-Gbps SFP+ on Brocade 16-Gbps switches running Fabric OS
version 7.1 or later. There is no support for D_Port connectivity between an HBA and an Access
Gateway. See “Limitations and considerations for D_Port with HBAs” on page 99.
The following equipment is supported:
• HBAs: Driver v3.1 provides limited support for D_Port. Driver v3.2 provides extensive support
for D_Port, including dynamic D_Port mode.
• Switches: Brocade DCX 8510-4, DCX 8510-8, 6505, 6510, 6520

For configuration details see “Using D_Port with HBAs” on page 97.
NOTE
The following examples use command-line interface (CLI) commands. Refer also to the latest
Brocade Host Connectivity Manager (HCM) and Brocade Network Advisor documentation to use
those graphical user interface (GUI) applications to configure D_Port.
Using D_Port without HBAs
The topics in this section apply to Topologies 1 through 3:
• “Enabling D_Port” on page 95
• “Disabling D_Port” on page 97
• “Saving port mappings on an Access Gateway” on page 97
Enabling D_Port
For complete information on the portDportTest and portCfgDport commands, refer to the Fabric OS
Command Reference.
Use this procedure to configure a basic D_Port diagnostics session between two switches. Refer to
Figure 3 on page 91.
