OPERANDS
This command has the following operands:
--slot slot
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 slot are tested. Valid
number values include the following:
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 the following:
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.
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.
DIAG-STATS
The ASIC internal error counters detected an error in the received frame. This
error is similar to ERRSTATS, but includes verifying the Tx/Rx frame count
statistics. The DIAG-STATS error can be caused by a faulty SFP or indicate
deeper problems in the main board or ASIC. Check for a faulty SFP. Replace the
cable or SFP if necessary.
