fcrPathTest
OPERANDS
This command has the following operands:
--slot slot
-unit number
-path mode
-nframes count
DIAGNOSTICS
When a failure is detected, the test may report one or more of the following:
DIAG-DATA
DIAG-ERRSTAT
DIAG-INIT
DIAG-PORTDIED
DIAG-STATS
318
Specifies the slot number on which the diagnostic operates. The default is 0 and
operates on fixed-port-count products.
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
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
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.
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.
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.
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.
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.
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.
