portCfgDPort 2 portCfgDPort Configures a port as a D_Port. SYNOPSIS portcfgdport --enable [-dwdm] [slot/]port_list portcfgdport --disable [slot/]port_list portcfgdport --help DESCRIPTION NOTES OPERANDS Use this command to configure a diagnostic port (D_Port). The D_Port is not part of the fabric. It does not carry any interswitch traffic or data traffic. The D_Port is used solely for the purpose of running link-level diagnostics between two switches and to isolate link level fault on the port, in the small form factor pluggable (SFP), or in the cable. You must configure both ends of the link between a given pair of switches, and you must disable the port before you can configure a D_Port. Re-enabling the D_Ports will automatically start the diagnostics when the ports come online. The D_Port test performs the following diagnostics: • An electrical loopback test (supported only on 16G SFPs capable of electrical loopback) • An optical loopback test (supported only on 16G SFPs capable of optical loopback) • A link traffic test • A link distance measurement The execution of this command is subject to Virtual Fabric or Admin Domain restrictions that may be in place. Refer to Chapter 1, "Using Fabric OS Commands" and Appendix A, "Command Availability" for details. This command is supported only on Fibre Channel ports. SFPs must be 10Gb or 16Gb Brocade-branded SFPs and run Fabric OS v7.0.0 or later. This command is not supported on the Brocade FC8-32E and Brocade FC8-48E port blades. D_Port configuration is not supported on EX_Ports and ports configured in encryption mode or compression mode. Links with mismatched D_Port configuration will be segmented or disabled. Forward Error Correction (FEC) is not supported on D_Ports configured with Dense Wavelength Division Multiplexing (DWDM). This command has the following operands: slot On bladed systems only, specifies the slot number of the ports to be configured, followed by a slash (/). port_list Specifies one or more ports, relative to the slot on bladed systems. Use switchShow for a listing of valid ports. A port list should be enclosed in double quotation marks and can consist of the following: • A single port, for example, "8" or "5/8" on blades systems. • A port range where beginning and end port are separated by a dash, for example, "8-13" or "5/8-13" on blades systems. A port range cannot span multiple slots. • A set of ports separated by spaces, for example "3 5 7 8"or 5/3 5/5 5/7 5/8 on bladed systems. Fabric OS Command Reference 663 53-1002746-01
