Portcfgdport - Brocade Communications Systems Brocade 8/12c Command Reference Manual

portCfgDPort

Configures a port as a D_Port.
SYNOPSIS
portcfgdport --enable [slot/]port_list
portcfgdport --disable [slot/]port_list
portcfgdport --help
DESCRIPTION
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:
•
•
•
•
NOTES
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 10G or 16G Brocade-branded
SFPs and run Fabric OS v7.0.0 or later.
D_Port configuration is not supported on interchassis link (ICL) ports, EX_Ports, F_Ports, or N_Ports
(both in Access Gateway and Host Bus Adapters). D_Port configuration will fail if the port is configured in
R_RDY mode, encryption mode, or compression mode. Links with D_Port configuration mismatch will
segment.
OPERANDS
This command has the following operands:
slot
port_list
Fabric OS Command Reference
53-1001764-01
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
On bladed systems only, specifies the slot number of the ports to be configured,
followed by a slash (/).
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.
