Diagnostic Port
Diagnostic Port (D_Port) mode allows you to convert a Fibre Channel port into a diagnostic port for
testing link traffic and running electrical loopback and optical loopback tests. The test results can be
very useful in diagnosing a variety of port and link problems.
You can run D_Port tests between the following:
• A pair of switches
• A pair of Access Gateways
• An Access Gateway and a switch
• A switch and a host bus adapter (HBA)
• An Access Gateway and a HBA
The HBAs can be Brocade or non-Brocade HBAs. The non-Brocade HBAs must have Brocade HBA
D_Port support and Fabric Vision license.
Supported platforms for D_Port
D_Port functionality is supported only on 16 Gbps-capable platforms, running Fabric OS 7.0.0 or later.
The ports must use 10 Gbps or 16 Gbps Brocade-branded SFP transceivers. It is also supported on 8-
Gbps LWL SFP, 8-Gbps ELWL SFP, ICL ports, QSFP, and QSFP+ ports.
