Debugging spinFab errors

Link errors and tx/rx errors are seen when the spinFab test fails.
Link errors
Once the frame is sent out of the port, the spinFab command monitors the link errors in the ASIC.
If any of the error counters are non-zero, spinFab reports ERROR and the test fails on the port.
If you receive any of the errors listed above, then follow the suggested debugging procedures:

The spinFab command does not clear any existing error counters before running the test. You
should first clear all error counters and re-run the spinFab command.
Verify that the link comes up by enabling and disabling the local or remote ports.
Verify that the source of the error is either local port or remote port. This can be done by
monitoring the port statistics on both the ends simultaneously. Refer to
statistics" on page 106 for more information on how to display the statistics for a port.
Verify that the cables and SFPs are inserted properly. Remove and insert them again on both
the ends.
Verify that the failing local port is working fine when connected to another remote port.
Similarly, check whether the failing remote port is working fine when connected to another
local port.
Once the fault is isolated on either the local or remote port, replace the cable and SFPs
connected to the local and remote ports.
In case of loopback ports, change the loopback plug. Refer to
more information on changing the loopback plug.
