Failure report
Displays details on the local port and remote port errors, if any, when the D_Port
test fails.
Use the --show all command to display the following test summary information:
Port
The port number on the local side of the link
State
The port state: OFFLINE or ONLINE
SFP Capabilities
Electrical loopback (E) or optical loopback (O), or both (E, O)
Test Result
PASSED, FAILED, or STOPPED
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 Brocade-branded and run Fabric
OS v7.0.0 or later. This command skips the optical loopback test for loopback plugs or when the port
loops back to another D_Port in the same switch.
The port error statistics may show incremented values after D_Port tests are successful due to port
toggle operation at the end of the D_Port test.
The approximate cable distance is calculated and displayed instead of estimated cable distance if the
"electrical loopback" and "optical loopback" tests statuses are SKIPPED. The associated value of
Approximate/Estimated cable distance will be UNKNOWN if the "electrical loopback" and "optical
loopback" tests statuses are "SKIPPED" and the link distance is less than 150 meters.
OPERANDS
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 commas, for example "3,5,7,8" or "5/3,5,7,8" on
bladed systems.
• A wildcard '*' indicates all ports. The wildcard can be represented as '*', or "*".
--start
Initiates the diagnostics on the specified D_Ports.
-nframes number
Specifies the number of frames to send in millions. The default value is 1 for 1
million frames.
-time time
Specifies the time duration in HH:MM format for which the frame traffic test will
run.
