Diagnostic Port (D_Port)
D_Port mode allows you to convert a Fibre Channel port into a diagnostic port for testing link traffic,
electrical loopbacks, and optical loopbacks between a pair of switches, a pair of Access Gateways,
and an Access Gateway and a switch. The ports must use 10G or 16G Brocade-branded SFPs.
Support is also provided for running D_Port tests between a host bus adapter (HBA) and a switch.
The test results that are reported can be very useful in diagnosing a variety of port and link
problems.
