Diagnostic Port ∙ Brocade 16-Gbps HBA (Brocade Fabric Adapter 1860) ports operating in HBA mode with a 16-Gbps SFP+ on Brocade 16Gbps switches running Fabric OS version 7.1 or later. ∙ Non-Brocade 16-Gbps HBAs: Emulex LPe16002B-M6, QLogic QLE-2672, QLogic 1860-2P ∙ Non-Brocade 32-Gbps HBAs: Emulex LPe32000B, QLogic QLE2764, QLogic QLE2742 Brocade HBA v3.1 provides limited support for D_Port. Brocade HBA v3.2 provides extensive support for D_Port, including dynamic D_Port mode. ∙ Non-Brocade 16-Gbps HBAs (must have HBA D_Port support) For applicable topologies, refer to "Supported topologies" in this chapter. For D_Port functionality with 8-Gbps SFP transceivers, the switch must be running Fabric OS 7.2.1 or later. To run D_Port tests on a link with 8-Gbps SFP transceivers, both ends of the link must have the same type of SFP. That is, both ends of the link must have LWL SFPs or both ends must have ELWL SFPs. Licensing requirements for D_Port The D_Port feature does not require a license if you are running tests between a pair of Brocade devices, whether the devices are switches, Access Gateways, or HBAs. If you want to run D_Port tests between a switch and a non-Brocade HBA, the Fabric Vision license for Gen6 and Gen5 or the combination of the Fabric Watch license and the Advanced Performance Monitoring license for Gen5 only is required. Also, the HBA vendor must have implemented Brocade HBA D_Port support. Starting with Fabric OS 7.3.2, you can also run D_Port tests if you have a Fabric Watch and Performance Monitor combo license. Understanding D_Port A port in D_Port mode does not carry any user traffic, and is designed to run only specific diagnostics tests for identifying link-level faults or failures. To bring up a port in D_Port mode, follow these basic steps: 1. Disable the ISL capability on the ports by issuing the no fabric isl enable command. 2. Enable D_Port functionality on both ends of the link. 3. Enable the ISL capability on the ports by issuing the fabric isl enable command. The following figure illustrates an example D_Port connection between a pair of switches through SFP transceivers (port assignments will vary). NOTE With Gen 6, Fabric OS supports 10-, 16-, and 32-Gbps connections. Brocade Fabric OS Administration Guide, 8.0.1 416 53-1004111-02
