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 Brocade FR4-18i blades and Brocade 7500 platforms.
The switch must be offline for this test to run.
Operands This command has the following operands:
--slot slotnumber Specifies the slot number on which the diagnostic operates. The default is 0
and operates on fixed-port-count products.
-unit number Specifies the FC Router FPGA to test. By default, all FC Router FPGAs in the
specified slotnumber are tested. Valid number values include:
0 FC Router FPGA 0
1 FC Router FPGA 1
2 All FC Router FPGAs
-path mode Specifies the loopback point for the test. By default, fcrPathTest uses the
Central ASIC loopback. Valid mode values include:
1 Central ASIC loopback
2 FC Router FPGA Serdes loopback
3 FC Router FPGA internal loopback
-nframes count Specifies the number of frames to send. The test progresses until the
specified number of frames are transmitted on each port. The default value is
10.
Examples To test slot 2 with FC Router FPGA Serdes loopback sending 10 frames:
switch:admin> fcrpathtest --slot 2 -path 2 -nframes 10

passed.
Diagnostics When a failure is detected, the test may report one or more of the following:
DIAG-DATA The payload received by the specified port did not match the transmitted
payload. A cable, media, or ASIC failure is the probable cause. Check for a
faulty SFP. Replace the SFP if necessary.
DIAG-ERRSTAT One of the ASIC internal counters detected a frame statistics error in the
received frame. A cable, media, or ASIC failure is the probable cause. Check
for a faulty SFP. Replace the SFP if necessary.
DIAG-INIT The port failed to synchronize in the loopback mode requested. A cable,
media, or ASIC failure is the probable cause. Check for a faulty SFP. Replace
the SFP if necessary.
DIAG-PORTDIED The specified port was in loopback mode and then lost sync. A cable, media,
or ASIC failure is the probable cause. Check for a faulty SFP. Replace the SFP
if necessary.
